Add confirmed repository deletion tool (#3076)
* feat(repos): add confirmed repository deletion Add a destructive delete_repository tool that requires an exact owner/repo confirmation through multi-round-trip elicitation. Gate the tool to MCP protocol 2026-07-28 and newer across local and remote transports. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: 4b04480c-c2e9-483e-9b0f-34830b76a2f8 * refactor(inventory): generalize tool availability guards Gate protocol-restricted tools on required elicitation capabilities and enforce direct calls inside the registered handler so SDK result finalization remains intact.

feat(auth): add GitHub App server-to-server authentication for stdio
Add non-interactive GitHub App installation authentication to the stdio server, so headless deployments (CI, Kubernetes, background agents) can authenticate without a browser, device code, or elicitation. This is the outstanding follow-up tracked in #1333: OAuth login shipped the interactive user-to-server flows, but PEM-based server-to-server auth was still needed to remove the interactive requirement. The new internal/githubapp package signs a short-lived RS256 JWT with the app's private key, exchanges it for an installation access token, and refreshes it transparently before expiry. It exposes a Provider whose AccessToken method mirrors oauth.Manager so it plugs into the existing BearerAuthTransport token provider. Only the standard library and golang.org/x/oauth2 are used. The private key is injected safely: a file path (GITHUB_APP_PRIVATE_KEY_PATH, preferred — mountable as a secret and kept off argv and out of the environment) or an inline GITHUB_APP_PRIVATE_KEY env var. There is intentionally no flag for the key contents, which would otherwise leak via the process command line. App auth is mutually exclusive with a PAT and with OAuth login. A loud startup warning and a dedicated docs page (docs/github-app-auth.md, with Docker and Kubernetes examples) cover the security considerations: this injects a high-privilege credential alongside the agent and is not recommended without an independent security review.

fix(mcp-apps): reconcile the show/defer contract — render results, remove show_ui (#2774)
* fix(ui): render success view when an MCP App tool executed up-front The create_pull_request / issue_write / update_pull_request Views decided form-vs-success from in-app submit state only, ignoring the tool-result the host delivers on render. Per the MCP Apps 2026-01-26 spec the host renders a View whenever the tool carries _meta.ui.resourceUri — independent of whether the server deferred or executed. So when the server executed up-front (e.g. show_ui=false, or parameters the form can't represent) the View still showed its "Create pull request" input form over an already-created PR, which reads as a bug (it even shows a PR number). Drive the Views off the result instead: a new shared completedToolResult() helper returns parsed data only for a genuine completed success, and returns null for the awaiting_user_submission deferral sentinel, errors, or no result. Each write View now shows its success card when that completed result is present, so the form is only ever shown while the action is genuinely deferred. Reconciles the show/defer state machine at the View (decision layer that the host result feeds). See github/copilot-mcp-core#1864. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(ui): scope tool-result to the current invocation Address review feedback: the write Views derive their success card from `toolResult`, but it wasn't cleared when a new invocation arrived (only the in-app `successPR`/`successIssue` was reset on `toolInput` change). A completed result from a previous invocation could briefly render a stale success card over the next, still-deferred form. Clear `toolResult` whenever a new `tool-input` notification arrives. The spec guarantees `tool-input` precedes that invocation's `tool-result`, so this scopes the result to the current invocation centrally in the hook — fixing all three Views without per-app invocation keys. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(mcp-apps): remove show_ui — it can't suppress app rendering show_ui promised "skip the form and execute directly", but it can't deliver: the host renders an MCP App for any tool that carries _meta.ui.resourceUri, and the 2026-01-26 MCP Apps spec has no per-call/per-result way to opt out of rendering. show_ui only flipped the server's defer decision, so show_ui=false created the PR/issue up-front yet the host still rendered the app — exactly the contradiction this work set out to fix. And show_ui is only ever exposed to clients that support UI, i.e. precisely the clients that always render the app. Remove it entirely: - Drop the show_ui schema property, the form-param allowlist entry, and the showUI term from the defer predicate in create_pull_request and issue_write. The gate is now FF && clientSupportsUI && !_ui_submitted && !hasNonFormParams. - Delete the now-unused UI-only schema-property strip machinery in pkg/inventory (uiOnlySchemaProperties, stripUIOnlySchemaProperties, stripSchemaProperties) and the exported ConditionalSchemaPropertyDescriptions, which existed solely to surface show_ui to UI-capable clients. _meta.ui stripping is untouched. - Drop the conditional-property annotation from the docs generator. - Update toolsnaps, generated docs, and tests. With the up-front-execution Views now rendering the result (success card), the remaining contract is simple: when MCP Apps are enabled the form is the path, and the form is only shown while the action is genuinely deferred. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(mcp-apps): centralize the show/defer decision (single source of truth) The defer-to-form predicate was triplicated across create_pull_request, update_pull_request, and issue_write, each with its own near-identical *HasNonFormParams function. As more MCP App tools are added this duplication would grow and the copies could silently drift. Extract one shared gate in ui_capability.go: - shouldDeferToForm(ctx, deps, req, args, formParams) — the single show/defer decision (MCP Apps enabled, client supports UI, not a form submission, and no non-form params). - hasNonFormParams(args, formParams) — one generic helper replacing the three per-tool functions. - uiSubmitted(args) — small shared predicate. Each handler is now a one-line `if shouldDeferToForm(...) { return awaiting }`. The per-tool form-parameter allowlists and the user-facing messages stay per-tool (that is the genuine per-tool config). Pure refactor — behavior unchanged; existing tests now exercise the generic helper.

feat(oauth): add stdio OAuth 2.1 login core library (1/4) (#2704)
* feat(oauth): add stdio OAuth 2.1 stdio login Introduce internal/oauth, a self-contained library that performs the user-facing GitHub OAuth login the stdio server uses to obtain a token without a pre-provisioned PAT. It is independent of MCP: client concerns (elicitation) sit behind the Prompter interface so the flows are testable without a live session. What it provides: - Authorization-code + PKCE flow with a local loopback callback server, state/CSRF validation, and XSS-safe result pages. - Device-authorization flow as a fallback (headless, containers). - A Manager that selects the most secure available channel (browser auto-open -> URL elicitation -> last-resort user action), runs a single flow at a time, and exposes a refreshing token source. Both GitHub OAuth Apps and GitHub Apps are supported without special casing: the token is modeled as an x/oauth2 refreshing TokenSource, so expiring GitHub App user tokens are renewed transparently (the gap that made a stored-token approach silently die after ~8h). When a client lacks secure URL elicitation and the flow falls back to a tool-response message, the message advises the user that their agent/CLI/ IDE does not appear to support URL elicitation and suggests requesting it for improved security. Tests exercise real protocol behavior against an httptest GitHub stand-in: PKCE challenge/verifier, GitHub App refresh-on-expiry, device polling, URL elicitation, declined prompts, the last-resort action with advisory, and single-flight concurrency. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(oauth): reap browser launcher and keep native callback on loopback Address code review: - openBrowser: reap the launcher process asynchronously so it does not linger as a zombie for the lifetime of the server. - listenCallback: take an explicit bindAll flag and bind to all interfaces only inside a container (where the published port arrives via eth0). A native run, even with a fixed callback port, now stays on 127.0.0.1 instead of 0.0.0.0. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(oauth): fail fast when a fixed callback port is unavailable A fixed --oauth-callback-port is registered with the OAuth app and chosen deliberately, so a bind failure means another process holds the port and could intercept the authorization redirect. Treat that as fatal instead of silently downgrading to the device flow, which would mask the conflict. Also warn, when binding the callback inside a container, that the listener is on all interfaces and should be published to loopback only so the authorization code is not exposed on the container network. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(oauth): surface refresh failures, bound refresh, prefer device flow when headless Addresses pre-merge review of the OAuth stdio core: - Log a one-time warning when token refresh fails instead of silently returning an empty access token, so a forced re-login isn't a surprise. - Bound each background token refresh with a 30s HTTP client timeout so a stalled GitHub token endpoint can't block tool calls indefinitely. - On a headless host (no display server) with a random callback port, fall back to the device-code flow — the only channel reachable from a browser on another machine — instead of dead-ending on an unreachable localhost redirect. A generic browser-open failure still offers the manual URL. - Mark the callback bind failure with a sentinel so the fixed-port-busy fatal path can't misreport an unrelated error as a port conflict. - Export NormalizeHost so callers can recognize the default github.com host (consumed by the build-time baked-in credential guard). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * feat(oauth): wire stdio OAuth 2.1 login into the server (2/4) (#2710) * feat(oauth): wire stdio OAuth 2.1 login into the server Connect the internal/oauth core library to the stdio MCP server so users can authenticate with an OAuth App or GitHub App client ID instead of a static personal access token. - BearerAuthTransport gains a TokenProvider that is consulted per request, letting the lazily-acquired, auto-refreshing OAuth token take effect without rebuilding the client. - createGitHubClients uses BearerAuthTransport (and skips go-github's WithAuthToken, which would pin a static token) when a TokenProvider is set. - RunStdioServer starts without a token and installs receiving middleware that runs the authorization flow on the first tool call, surfacing the auth URL or device code via elicitation (or a tool result as a fallback). - Tool filtering uses the requested OAuth scopes; the default supported set hides nothing, while a narrower --oauth-scopes both narrows the grant and filters tools accordingly. - A sessionPrompter adapts the MCP server session to oauth.Prompter, keeping the authorization URL off the model's context. - New stdio flags: --oauth-client-id/-client-secret/-scopes/-callback-port. This is stdio-only and deliberately does not touch MCP-HTTP auth. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(oauth): address review — omit empty bearer header, guard token/oauth - BearerAuthTransport omits the Authorization header entirely when the token is empty (pre-authorization) rather than sending an empty "Bearer " value. - RunStdioServer rejects the ambiguous combination of a static Token and an OAuthManager up front, enforcing the documented mutual exclusivity. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(oauth): clarify SupportedScopes is the stdio default and tool filter Document that stdio OAuth login requests these scopes by default and then filters the exposed tools to the scopes actually granted, so a tool whose required scope is absent from this list is hidden under default OAuth even though a PAT carrying that scope would expose it. Keep the list in sync with tool scope requirements when scopes change. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Distinguish undeliverable auth prompts from user declines An elicitation prompt that the client cannot deliver (a transport or protocol failure) was treated the same as a user actively declining: any display error cancelled the flow. That conflated a system failure with a deliberate "no", so a client that advertised URL elicitation but failed to deliver it would hard-fail the login instead of degrading. Add an ErrPromptUnavailable sentinel alongside ErrPromptDeclined and have the MCP adapter return it when Elicit fails at the transport level. The manager now falls back to the manual user-action channel on an undeliverable prompt (keeping the background flow alive so the user can still authorize out of band), while a genuine decline still aborts. A context-cancelled prompt is checked first so an ending flow is never misread as a transport failure. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * build(oauth): bake in default OAuth credentials for official releases (3/4) (#2711) * build(oauth): bake in default OAuth credentials via build-time ldflags Inject the public OAuth client credentials (stored as the OAUTH_CLIENT_ID and OAUTH_CLIENT_SECRET repo secrets) at build time via -ldflags so official binaries and images ship a working default app for zero-config login. Security relies on PKCE, not on the secret. Local/dev builds leave the values empty and continue to require an explicit token or --oauth-client-id. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(oauth): recognize github.com host aliases for the baked-in client Match the default host via oauth.NormalizeHost instead of only an empty host string, so an explicit GITHUB_HOST=github.com (or api.github.com) still counts as the default and keeps zero-config baked-in login working. GHES and ghe.com users continue to bring their own --oauth-client-id. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(oauth): document stdio OAuth login; make PAT optional in install config (#2717) Add a dedicated Local Server OAuth Login guide (docs/oauth-login.md) covering the PKCE/device flows, display channels and the URL-elicitation security advisory, scope-based tool filtering, the fixed-port Docker recipe and its loopback/port-safety behavior, bringing your own OAuth or GitHub App, and the GitHub Enterprise Server / ghe.com requirement to register an app on that host (custom --gh-host directs login at that instance's authorization server). Reflect that the local server now logs in with OAuth by default on github.com: - README: make the stdio Docker install badges OAuth-first (fixed callback port 8085 published to loopback), drop the PAT prompt, and reframe the PAT as an optional alternative with a pointer to the new guide. - server.json: make GITHUB_PERSONAL_ACCESS_TOKEN optional and publish the OAuth callback port so the registry default works without a token.

Add explicit show_ui parameter to UI-enabled write tools (#2601)
* Add explicit show_ui parameter to UI-enabled write tools
Today the server decides whether to route issue_write and create_pull_request
through the MCP App form using two implicit signals: _ui_submitted (set by
the form on submit) and a heuristic that bypasses the form when the call
carries any parameter the form cannot represent (labels, assignees,
issue_fields, state, reviewers, etc.). The model had no first-class,
documented way to say "execute directly, do not show a form".
Add a show_ui boolean parameter to the input schema of IssueWrite,
LegacyIssueWrite, and CreatePullRequest. It defaults to true and is
visible only to clients that advertise MCP App UI support: the strip
happens per-request in inventory.ToolsForRegistration via a new
stripUIOnlySchemaProperties helper, gated by the same predicate that
already strips _meta.ui (shouldStripMCPAppsMetadata). The two strips share
one decision so the schema and metadata stay in lock-step.
Form-routing predicate becomes:
MCPApps FF on && client supports UI &&
!_ui_submitted && show_ui && !hasNonFormParams
show_ui=false is a new explicit way for the model to opt out. The existing
non-form-param auto-bypass stays as a safety net, and the React forms keep
sending _ui_submitted=true on submit unchanged. get_me is out of scope
because its UI is pure client-side card rendering with no server-side
gating to replace.
The current strip gate ("strip when FF is off OR capability explicitly
absent") mirrors today's _meta.ui behavior exactly, including the
"capability unknown" case. For stdio that means UI-capable schemas are
exposed to any FF-enabled client. The handler-side clientSupportsUI check
still gates form execution at call time, so it is functionally a no-op for
non-UI stdio clients. A separate follow-up will tighten the gate to
"strip on unknown too" and wire an InitializedHandler in stdio to
re-register the un-stripped surface only after a UI-capable client has
advertised; the two changes must ship together to avoid breaking stdio.
docs/feature-flags.md and docs/insiders-features.md include an unrelated
"reviewers" description update picked up by script/generate-docs from

feat(http): ignore proxy forwarding headers by default
X-Forwarded-Host and X-Forwarded-Proto were unconditionally honored when constructing OAuth resource metadata URLs. In HTTP-mode deployments that do not set --base-url and are not fronted by a proxy that strips these headers, this lets an on-path client influence the URL advertised in WWW-Authenticate and the /.well-known/oauth-protected-resource body. This is a hardening change rather than a true vulnerability — exploiting it requires HTTP without --base-url plus an attacker already positioned to inject the header — but the unsafe default is worth closing. Default behavior now derives host/scheme from r.Host and the TLS state. Setups that rely on a trusted internal forwarder (e.g. an in-cluster gateway that needs to preserve the originating hostname per request) can opt back in with --trust-proxy-headers / GITHUB_TRUST_PROXY_HEADERS=1. --base-url continues to take precedence in all cases.

docs: auto-generate per-flag tool lists for insiders and feature flags (#2521)
Adds two auto-generated documentation sections that describe how feature flags shape the tool surface: - docs/insiders-features.md gets a per-flag block under its existing hand-written prose. Each Insiders flag whose tools differ from the default surface is listed with the full tool schema rendered through the same writer used for README, so contributors can see exactly what Insiders Mode adds or changes. - docs/feature-flags.md is new and gives the same treatment to every flag in AllowedFeatureFlags (user-controllable flags). It links back to the Insiders doc for the auto-enabled subset. Both sections are produced by a single generator that diffs the flag-on inventory against the default-flagged inventory and reports any tool that is new or has a different InputSchema/Meta. No reason classification - just tools and their schemas, kept intentionally simple so contributors don't have to update the generator when adding a new flag.

feat(issues): gate issue-fields features behind remote_mcp_issue_fields flag (#2520)
* feat(issues): gate issue-fields features behind remote_mcp_issue_fields flag Gates the recently merged issue-fields work (list_issue_fields tool, field_values enrichment on list_issues/search_issues, and field_filters input on list_issues) behind a new feature flag, also enabled in insiders mode. - list_issues splits into two same-named registrations: the field-aware variant requires the flag, while LegacyListIssues (FeatureFlagDisable) preserves the prior schema and GraphQL selection set so disabled callers don't pay the extra wire/server cost. - search_issues skips the field-values lookup when the flag is off. - list_issue_fields requires the flag to be registered at all. - Adopts <tool>_ff_<flag>.snap naming for flagged toolsnap variants so same-named duplicates each get a distinct snapshot. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: address PR review on issue-fields gating - docs generator: install a no-flags feature checker so README reflects the default user experience (tools enabled with no special flags), fixing duplicate `list_issues` and removing granular/flagged-only tools that were never meant to appear in the default docs. - csv_output: drop the FeatureFlagEnable/Disable exclusion in isCSVOutputTool. Wrapping happens before the per-request flag filter picks the live variant, so flag-gated list_* tools wrap safely; this restores CSV conversion for `list_issues` and enables it for `list_issue_fields` when both flags are on.

* Add CSV output for list tools under insiders mode * fix: resolve rebase feature flag conflicts Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Simplify feature-flag handling: collapse CSV dual-variant + skip filtering when no checker (#2516) * refactor: generic toolset+name sort, clarify feature flag intent Address review feedback on #2450: - Collapse the three near-identical sort helpers in pkg/inventory/filters.go into a generic sortByToolsetThenName so adding new inventory item types doesn't require copying the comparator. - Expand the doc comments on the three *WithoutFeatureFiltering helpers to spell out why they exist: HTTP mode builds a static (process-wide) inventory as an upper bound, but per-request feature flags from headers (X-MCP-Features, X-MCP-Insiders) are evaluated later, so feature-flagged variants must be preserved here. - Strengthen the doc comment on ResolveFeatureFlags to make the contract explicit: user-supplied flags are validated against AllowedFeatureFlags, but insiders expansion deliberately is not — InsidersFeatureFlags may include server-controlled flags that are not user-toggleable. CORS comments are intentionally left for the PR author. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(feature-flags): clarify allowed and insiders sets are independent Also add tests covering: - a user-toggleable flag (FeatureFlagIssuesGranular) that insiders does not turn on automatically - insiders mode not turning on user-only allowed flags Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(inventory): collapse three *WithoutFeatureFiltering helpers into StaticUpperBound The three parallel methods (AvailableToolsWithoutFeatureFiltering, AvailableResourceTemplatesWithoutFeatureFiltering, AvailablePromptsWithoutFeatureFiltering) were always called as a triple in exactly two places: HTTP buildStaticInventory and its test mirror. They exist because the dual-variant pattern (sibling tools with mirrored FeatureFlagEnable / FeatureFlagDisable on the same name, e.g. CSV output) makes feature filtering at static-build time impossible — both variants must be kept and resolved per-request. Replace the three with one method, Inventory.StaticUpperBound(ctx), that returns (tools, resources, prompts) and carries the rationale in its doc comment. Reduces API surface, eliminates the triplication, and makes the single "skip feature filtering" concept obvious to readers. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor: simplify feature-flag handling Two related simplifications, both about treating insiders as a meta flag that expands once at startup and then stops mattering: - Collapse CSV's dual-variant pattern into a single tool whose handler performs a runtime feature-flag check via deps.IsFeatureEnabled. CSV is a pure response-format toggle, not a schema change, so it does not need the dual-name pattern that genuine schema variants (granular issues/PRs) still use. - When no feature checker is installed, skip feature-flag filtering and return the full upper bound. The static HTTP inventory now uses plain AvailableTools/Resources/Prompts; the per-request inventory always installs a checker, so MCP registration (which serves a tool name once) always sees a deduplicated set. The bespoke StaticUpperBound helper and the isToolEnabledWithFeatureFlags split go away. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * ci(mcp-diff): add insiders + per-feature configs The mcp-diff matrix now includes: - --insiders (and --insiders --read-only) - one config per github.AllowedFeatureFlags entry, generated by script/print-mcp-diff-configs so new user-controllable flags get diffed automatically without editing the workflow Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * docs(insiders): explain feature-flag resolution for contributors Adds a 'How feature flags are resolved' section covering: - Insiders is a meta flag, like 'all'/'default' for toolsets - User input -> allowlist filter -> insiders expansion -> server-side fallback (remote only) - AllowedFeatureFlags vs InsidersFeatureFlags are independent - How to add a new feature flag, including the TestGitHubPackageDoesNotReadInsidersMode guard Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(inventory): make feature-flag gating a regular ToolFilter Move tool feature-flag evaluation out of isToolEnabled and into a ToolFilter installed at the head of the pipeline by Build() when WithFeatureChecker received a non-nil checker. The 'no checker = no filtering' contract is now expressed structurally (the filter isn't installed) instead of by a runtime nil check inside the helper. Resources and prompts have no filter pipeline, so they call the now-pure featureFlagAllowed helper behind an explicit r.featureChecker != nil guard at the iteration site. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * perf(inventory): cache extracted toolset IDs in sort comparator Avoid evaluating the extractor closures up to three times per comparison.

The config generator gains a -transport flag: - stdio (default, unchanged behaviour) - http-headers (emits headers-only configs targeting a shared server) Two new combined entries layer multiple headers together as a smoke test for header-merging regressions.

refactor: remove dynamic toolsets and deprecated closure constructor (#2512)
Dynamic toolset discovery (the meta-tools enable_toolset, list_available_toolsets, get_toolset_tools and the --dynamic-toolsets / GITHUB_DYNAMIC_TOOLSETS switch) was a local-only feature never offered by the remote server. Removing it deletes a meaningful chunk of branching, configuration surface and tests for a path no longer in active use. The deprecated closure-based NewServerToolWithDeps generic constructor was only kept around for the dynamic tool registration path and is removed together with it. Going forward there are exactly two constructors: - NewServerTool — raw mcp.ToolHandler, no closure, no unmarshalling - NewServerToolWithContextHandler[In, Out] — typed handler, deps via context Inventory methods that only existed for the dynamic path (ToolsForToolset, IsToolsetEnabled, EnableToolset, EnabledToolsetIDs) are removed. ResolvedEnabledToolsets loses its dynamic flag. Also strips dynamic references from the README, server configuration docs, copilot-instructions, mcp-diff workflow, and conformance-test script.

feat(http): enforce static CLI flags as upper bound for per-request filtering
The HTTP server now respects the same static CLI flags as the stdio server: --toolsets, --tools, --exclude-tools, --read-only, --dynamic-toolsets, and --insiders. A static inventory is built once at startup from these flags, producing a pre-filtered tool/resource/prompt universe. Per-request headers (X-MCP-Toolsets, X-MCP-Tools, etc.) can only narrow within these bounds, never expand beyond them. When no static flags are set, the existing behavior is preserved — headers have full access to all toolsets. Fixes #2156 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

Use translation strings for server name/title override
Instead of new CLI flags (--server-name, --server-title), reuse the existing string override mechanism that already supports tool title/ description overrides throughout the codebase. Users can now configure the server name and title via: - GITHUB_MCP_SERVER_NAME / GITHUB_MCP_SERVER_TITLE env vars - "SERVER_NAME" / "SERVER_TITLE" keys in github-mcp-server-config.json This is consistent with how all other user-visible strings are overridden (e.g. GITHUB_MCP_TOOL_GET_ME_USER_TITLE). No new struct fields or CLI flags are needed. Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com> |

Update automation to use toolset IDs instead of display names
The generate-docs command now outputs toolset IDs (e.g., `actions`, `code_security`) wrapped in backticks instead of display names (e.g., "Actions", "Code Security"). This ensures the manual changes from PR #1756 persist when the docs are regenerated, fixing the issue where users need to configure the actual toolset ID, not the display name. Changes: - Modified generateRemoteToolsetsDoc() to use `idStr` instead of `formattedName()` - Modified generateRemoteOnlyToolsetsDoc() to use `idStr` instead of `formattedName()` - Both functions now wrap the toolset ID in backticks for clarity Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com> |

Make scope filtering always enabled (remove flag)

Add PAT scope filtering for stdio server
Add the ability to filter tools based on token scopes for PAT users. This uses an HTTP HEAD request to GitHub's API to discover token scopes. New components: - pkg/scopes/filter.go: HasRequiredScopes checks if scopes satisfy tool requirements - pkg/scopes/fetcher.go: FetchTokenScopes gets scopes via HTTP HEAD to GitHub API - pkg/github/scope_filter.go: CreateScopeFilter creates inventory.ToolFilter Integration: - Add --filter-by-scope flag to stdio command (disabled by default) - When enabled, fetches token scopes on startup - Tools requiring unavailable scopes are hidden from tool list - Gracefully continues without filtering if scope fetch fails (logs warning) This allows the OSS server to have similar scope-based tool visibility as the remote server, and the filter logic can be reused by remote server. |

feat: Add Octicon icons to MCP tools, resources, and prompts (#1603)
* Upgrade MCP Go SDK to v1.2.0-pre.1 and add Octicon icons to tools - Upgrade MCP Go SDK from v1.1.0 to v1.2.0-pre.1 for Icon support - Add Icon field to ToolsetMetadata for Octicon name assignment - Add OcticonURL() helper to generate CDN URLs for Octicon SVGs - Add Icons() method on ToolsetMetadata to generate MCP Icon objects - Apply icons automatically in RegisterFunc when tool is registered - Add icons to all 22 toolset metadata constants with appropriate Octicons - Update server.go to use new Capabilities API (fixes deprecation warnings) This demonstrates how the toolsets refactor makes adding new features simpler: icons are defined once in ToolsetMetadata and automatically applied to all tools in that toolset during registration. * Update third-party licenses for SDK upgrade * Address review feedback: enum size validation, mutation fix, tests - Replace runtime size validation with compile-time enum type (Size with SizeSM=16, SizeLG=24) - Fix RegisterFunc mutation by making shallow copy of tool before modifying Icons - Add comprehensive tests for octicons package (URL, Icons, Size constants) - Add toolsets tests for ToolsetMetadata.Icons(), RegisterFunc mutation prevention, and existing icon preservation - Improve icon choices for better visual semantics: - actions: play → workflow (more specific to GitHub Actions) - secret_protection: key → shield-lock (better represents protection) - gists: code → logo-gist (dedicated gist icon exists) * Add GitHub mark icon to server metadata Add the mark-github octicon to the server's Implementation struct so that MCP clients can display the GitHub logo for this server. The icon is provided in both 16x16 and 24x24 SVG sizes. * Fix rebase conflicts: use Registry methods and NullTranslationHelper - Remove duplicate old toolsets functions (AvailableToolsets, GetValidToolsetIDs, GetDefaultToolsetIDs) - Use Registry.AvailableToolsets() and Registry.HasToolset() instead - Replace stubTranslator with translations.NullTranslationHelper - Use new SDK Capabilities struct instead of deprecated HasTools/HasResources/HasPrompts - Add icon-related tests to registry_test.go * Use embedded data URIs for Octicon icons - Embed SVG icons using go:embed for offline use and faster loading - Convert icons to base64 data URIs at runtime - Fall back to CDN URL for non-embedded icons - Add test to verify all toolset icons are properly embedded - 44 SVG files (22 icons × 2 sizes) totaling ~27KB * Convert icons from SVG to PNG for MCP client compatibility MCP clients don't support SVG data URIs, so convert all embedded icons to PNG format using rsvg-convert. Changes: - Convert all 44 SVG icons to PNG format - Add 8 new icons: copilot, git-merge, repo-forked, star-fill - Update octicons.go to use PNG MIME type - Add script/fetch-icons for easy icon management - Update tests and toolsnaps for PNG format * Add mark-github icon for server metadata * Add light/dark theme icons for tools, resources, and prompts - Switch from size-based (16/24px) to theme-based (light/dark) icons - Use only 16x16 icons for smaller bundle size - Generate white (inverted) icons for dark theme backgrounds - Add icons to resources and prompts (auto-applied from toolset metadata) - Add 'file' icon for repository content resources - Update fetch-icons script to generate both theme variants * Use 24px icons with SVG fill modification for themes - Switch from 16px to 24px icons for better visibility - Use SVG fill attribute (#24292f for light, #ffffff for dark) instead of ImageMagick color inversion for cleaner theme variants - Remove ImageMagick dependency from fetch-icons script * Add specific icons for each repository resource type - repository_content: repo icon - repository_content_branch: git-branch icon - repository_content_commit: git-commit icon (new) - repository_content_tag: tag icon - repository_content_pr: git-pull-request icon Resources now have explicit icons set rather than relying on toolset fallback. * fix: restore Icon fields to toolset metadata and add icons to docs - Add Icon field to all ToolsetMetadata definitions (lost during rebase conflict resolution) - Update doc generator to include Octicon icons in toolsets table - Update doc generator to include icons in tool section headers - Use Primer Octicons CDN for GitHub markdown compatibility * feat: add icons to individual tools in documentation * fix: use repo-local icons with picture element for GitHub theme support - Reference icons from pkg/octicons/icons/ instead of external CDN - Use picture element with prefers-color-scheme for light/dark mode - GitHub markdown renderer will display these correctly * fix: remove redundant icons from individual tools Icons are kept on section headers and toolsets table only - having the same icon on every tool within a section was visually noisy and redundant. * Add icons to remote server toolsets documentation * Fix icon paths for docs/remote-server.md * Add remote-only toolsets with auto-generated documentation and icons guide - Add ToolsetMetadataCopilot, ToolsetMetadataCopilotSpaces, ToolsetMetadataSupportSearch - Add RemoteOnlyToolsets() function to return remote-only toolset metadata - Update doc generator to auto-generate remote-only toolsets table with icons - Create docs/toolsets-and-icons.md explaining how to add icons to toolsets - Add link to icons guide in CONTRIBUTING.md * Add icon validation tests and single source of truth for required icons - Add pkg/octicons/required_icons.txt as single source of truth for icons - Add RequiredIcons() function to read the required icons list - Update script/fetch-icons to read from required_icons.txt - Update octicons_test.go to use RequiredIcons() instead of hardcoded list - Add pkg/github/toolset_icons_test.go with: - TestAllToolsetIconsExist: validates all toolset icons are embedded - TestToolsetMetadataHasIcons: ensures all toolsets have icons set - Add 'book' icon for SupportSearch toolset - Update docs/toolsets-and-icons.md with fetch-icons and CI validation docs * fix: remove unused icon parameter from writeToolDoc - Remove unused 'icon' parameter from writeToolDoc function signature - Fix whitespace inconsistency in octicons_test.go - Fixes lint failure: unused-parameter revive error * fix: combine icon with name column in remote docs for proper table rendering - Move icon from separate column to Name column with <br> separator - Keep <picture> element for light/dark theme support - Remove empty icon column that was collapsing to zero width - Remove unused octiconSimpleImg function |

Changes: - ListWorkflows, ListWorkflowRuns, RunWorkflow, GetWorkflowRun - GetWorkflowRunLogs, ListWorkflowJobs, GetJobLogs - RerunWorkflowRun, RerunFailedJobs, CancelWorkflowRun - ListWorkflowRunArtifacts, DownloadWorkflowRunArtifact - DeleteWorkflowRunLogs, GetWorkflowRunUsage The new pattern: - Takes only translations.TranslationHelperFunc as parameter - Returns toolsets.ServerTool with Tool and Handler - Handler receives ToolDependencies for client access - Enables better testability and consistent interface Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> * refactor(git): migrate GetRepositoryTree to NewTool pattern * refactor(security): migrate code_scanning, secret_scanning, dependabot to NewTool pattern Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> * refactor(discussions): migrate to NewTool pattern Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> * Refactor security_advisories tools to use NewTool pattern Convert 4 functions from NewServerToolLegacy wrapper to NewTool: - ListGlobalSecurityAdvisories - GetGlobalSecurityAdvisory - ListRepositorySecurityAdvisories - ListOrgRepositorySecurityAdvisories Update tools.go toolset registration and tests. Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> * refactor: convert projects, labels, and dynamic_tools to NewTool pattern This PR converts projects.go, labels.go, and dynamic_tools.go from the legacy NewServerToolLegacy wrapper pattern to the new NewTool pattern with proper ToolDependencies. Changes: - projects.go: Convert all 9 project functions to use NewTool with ToolHandlerFor[map[string]any, any] and 3-return-value handlers - projects_test.go: Update tests to use new serverTool.Handler(deps) pattern - labels.go: Convert GetLabel, ListLabels, and LabelWrite to NewTool pattern - labels_test.go: Update tests to use new pattern - dynamic_tools.go: Refactor functions to return ServerTool directly (using NewServerToolLegacy internally since they have special dependencies) - tools.go: Remove NewServerToolLegacy wrappers for dynamic tools registration Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> * Add --features CLI flag for feature flag support Add CLI flag and config support for feature flags in the local server: - Add --features flag to main.go (StringSlice, comma-separated) - Add EnabledFeatures field to StdioServerConfig and MCPServerConfig - Create createFeatureChecker() that builds a set from enabled features - Wire WithFeatureChecker() into the toolset group filter chain This enables tools/resources/prompts that have FeatureFlagEnable set to a flag name that is passed via --features. The checker uses a simple set membership test for O(1) lookup. Usage: github-mcp-server stdio --features=my_feature,another_feature GITHUB_FEATURES=my_feature github-mcp-server stdio * Add validation tests for tools, resources, and prompts metadata This commit adds comprehensive validation tests to ensure all MCP items have required metadata: - TestAllToolsHaveRequiredMetadata: Validates Toolset.ID and Annotations - TestAllToolsHaveValidToolsetID: Ensures toolsets are in AvailableToolsets() - TestAllResourcesHaveRequiredMetadata: Validates resource metadata - TestAllPromptsHaveRequiredMetadata: Validates prompt metadata - TestToolReadOnlyHintConsistency: Validates IsReadOnly() matches annotation - TestNoDuplicate*Names: Ensures unique names across tools/resources/prompts - TestAllToolsHaveHandlerFunc: Ensures all tools have handlers - TestDefaultToolsetsAreValid: Validates default toolset IDs - TestToolsetMetadataConsistency: Ensures consistent descriptions per toolset Also fixes a bug discovered by these tests: ToolsetMetadataGit was defined but not added to AvailableToolsets(), causing get_repository_tree to have an invalid toolset ID. * Fix default toolsets behavior when not in dynamic mode When no toolsets are specified and dynamic mode is disabled, the server should use the default toolsets. The bug was introduced when adding dynamic toolsets support: 1. CleanToolsets(nil) was converting nil to empty slice 2. Empty slice passed to WithToolsets means 'no toolsets' 3. This resulted in zero tools being registered Fix: Preserve nil for non-dynamic mode (nil = use defaults in WithToolsets) and only set empty slice when dynamic mode is enabled without explicit toolsets. * refactor: address PR review feedback for toolsets - Rename AddDeprecatedToolAliases to WithDeprecatedToolAliases for immutable filter chain consistency (returns new ToolsetGroup) - Remove unused mockGetRawClient from generate_docs.go (use nil instead) - Remove legacy ServerTool functions (NewServerToolLegacy and NewServerToolFromHandlerLegacy) - no usages - Add panic in Handler()/RegisterFunc() when HandlerFunc is nil - Add HasHandler() method for checking if tool has a handler - Add tests for HasHandler and nil handler panic behavior - Update all tests to use new WithDeprecatedToolAliases pattern * refactor: Apply HandlerFunc pattern to resources for stateless NewToolsetGroup This change applies the same HandlerFunc pattern used by tools to resources, allowing NewToolsetGroup to be fully stateless (only requiring translations). Key changes: - Add ResourceHandlerFunc type to toolsets package - Update ServerResourceTemplate to use HandlerFunc instead of direct Handler - Add HasHandler() and Handler(deps) methods to ServerResourceTemplate - Update RegisterResourceTemplates to take deps parameter - Refactor repository resource definitions to use HandlerFunc pattern - Make AllResources(t) stateless (only takes translations) - Make NewToolsetGroup(t) stateless (only takes translations) - Update generate_docs.go - no longer needs mock clients - Update tests to use new patterns This resolves the concern about mixed concerns in doc generation - the toolset metadata and resource templates can now be created without any runtime dependencies, while handlers are generated on-demand when deps are provided during registration. * refactor: simplify ForMCPRequest switch cases * refactor(generate_docs): use strings.Builder and AllTools() iteration - Replace slice joining with strings.Builder for all doc generation - Iterate AllTools() directly instead of ToolsetIDs()/ToolsForToolset() - Removes need for special 'dynamic' toolset handling (no tools = no output) - Context toolset still explicitly handled for custom description - Consistent pattern across generateToolsetsDoc, generateToolsDoc, generateRemoteToolsetsDoc, and generateDeprecatedAliasesTable * feat(toolsets): add AvailableToolsets() with exclude filter - Add AvailableToolsets() method that returns toolsets with actual tools - Support variadic exclude parameter for filtering out specific toolsets - Simplifies doc generation by removing manual skip logic - Naturally excludes empty toolsets (like 'dynamic') without special cases * refactor(generate_docs): hoist success logging to generateAllDocs * refactor: consolidate toolset validation into ToolsetGroup - Add Default field to ToolsetMetadata and derive defaults from metadata - Move toolset validation into WithToolsets (trims whitespace, dedupes, tracks unrecognized) - Add UnrecognizedToolsets() method for warning about typos - Add DefaultToolsetIDs() method to derive defaults from metadata - Remove redundant functions: CleanToolsets, GetValidToolsetIDs, AvailableToolsets, GetDefaultToolsetIDs - Update DynamicTools to take ToolsetGroup for schema enum generation - Add stubTranslator for cases needing ToolsetGroup without translations This eliminates hardcoded toolset lists - everything is now derived from the actual registered tools and their metadata. * refactor: rename toolsets package to registry with builder pattern - Rename pkg/toolsets to pkg/registry (better reflects its purpose) - Split monolithic toolsets.go into focused files: - registry.go: Core Registry struct and MCP methods - builder.go: Builder pattern for creating Registry instances - filters.go: All filtering logic (toolsets, read-only, feature flags) - resources.go: ServerResourceTemplate type - prompts.go: ServerPrompt type - errors.go: Error types - server_tool.go: ServerTool and ToolsetMetadata (existing) - Fix lint: Rename RegistryBuilder to Builder (avoid stuttering) - Update all imports across ~45 files This refactoring improves code organization and makes the registry's purpose clearer. The builder pattern provides a clean API: reg := registry.NewBuilder(). SetTools(tools). WithReadOnly(true). WithToolsets([]string{"repos"}). Build() * fix: remove unnecessary type arguments in helper_test.go * fix: restore correct behavior for --tools and --toolsets flags Two behavioral regressions were fixed in resolveEnabledToolsets(): 1. When --tools=X is used without --toolsets, the server should only register the specified tools, not the default toolsets. Now returns an empty slice instead of nil when EnabledTools is set. 2. When --toolsets=all --dynamic-toolsets is used, the 'all' and 'default' pseudo-toolsets should be removed so only the dynamic management tools are registered. This matches the original pre-refactor behavior. * Move labels tools to issues toolset Labels are closely related to issues - you add labels to issues, search issues by label, etc. Keeping them in a separate toolset required users to explicitly enable 'labels' to get this functionality. Moving to issues toolset makes labels available by default since issues is a default toolset. * Restore labels toolset with get_label in both issues and labels This restores conformance with the original behavior where: - get_label is in issues toolset (read-only label access for issue workflows) - get_label, list_label, label_write are in labels toolset (full management) The duplicate get_label registration is intentional - it was in both toolsets in the original implementation. Added test exception to allow this case. * Fix instruction generation and capability advertisement - Expand nil toolsets to default IDs before GenerateInstructions (nil means 'use defaults' in registry but instructions need actual names) - Remove unconditional HasTools/HasResources/HasPrompts=true in NewServer (let SDK determine capabilities based on registered items, matching main) * Add tests for dynamic toolset management tools Tests cover: - list_available_toolsets: verifies toolsets are listed with enabled status - get_toolset_tools: verifies tools can be retrieved for a toolset - enable_toolset: verifies toolset can be enabled and marked as enabled - enable_toolset invalid: verifies proper error for non-existent toolset - toolsets enum: verifies tools have proper enum values in schema * Advertise all capabilities in dynamic toolsets mode In dynamic mode, explicitly set HasTools/HasResources/HasPrompts=true since toolsets with those capabilities can be enabled at runtime. This ensures clients know the server supports these features even when no tools/resources/prompts are initially registered. * Improve conformance test with dynamic tool calls and JSON normalization - Add dynamic tool call testing (list_available_toolsets, get_toolset_tools, enable_toolset) - Parse and sort embedded JSON in text fields for proper comparison - Separate progress output (stderr) from summary (stdout) for CI - Add test type field to distinguish standard vs dynamic tests * Add conformance-report to .gitignore * Add conformance test CI workflow - Runs on pull requests to main - Compares PR branch against merge-base with origin/main - Outputs full conformance report to GitHub Actions Job Summary - Uploads detailed report as artifact for deeper investigation - Does not fail the build on differences (may be intentional) * Add map indexes for O(1) lookups in Registry Address review feedback to use maps for collections. Added lookup maps (toolsByName, resourcesByURI, promptsByName) while keeping slices for ordered iteration. This provides O(1) lookup for: - FindToolByName - filterToolsByName (used by ForMCPRequest) - filterResourcesByURI - filterPromptsByName Maps are built once during Build() and shared in ForMCPRequest copies. * perf(registry): O(1) HasToolset lookup via pre-computed set Add toolsetIDSet (map[ToolsetID]bool) to Registry for O(1) HasToolset lookups. Previously HasToolset iterated through all tools, resourceTemplates, and prompts to check if any belonged to the given toolset. Now it's a simple map lookup. The set is populated during the single-pass processToolsets() call, which already collected all valid toolset IDs. This adds zero new iteration - just returns the existing validIDs map. processToolsets now returns 6 values: - enabledToolsets, unrecognized, toolsetIDs, toolsetIDSet, defaultToolsetIDs, descriptions * simplify: remove lazy toolsByName map - not needed for actual use cases FindToolByName() is only called once per request at most (to find toolset ID for dynamic enablement). The SDK handles tool dispatch after registration. A simple linear scan over ~90 tools is trivially fast and avoids: - sync.Once complexity - Map allocation - Premature optimization for non-existent 'repeated lookups' The pre-computed maps we keep (toolsetIDSet, etc.) are justified because they're used for filtering logic that runs on every request. * Add generic tool filtering mechanisms to registry package - Add Enabled field to ServerTool for self-filtering based on context - Add ToolFilter type and WithFilter method to Builder for cross-cutting filters - Update isToolEnabled to check Enabled function and builder filters in order: 1. Tool's Enabled function 2. Feature flags (FeatureFlagEnable/FeatureFlagDisable) 3. Read-only filter 4. Builder filters 5. Toolset/additional tools check - Add FilteredTools method to Registry as alias for AvailableTools - Add comprehensive tests for all new functionality - All tests pass and linter is clean Closes #1618 Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com> * docs: improve filter evaluation order and FilteredTools documentation - Add numbered filter evaluation order to isToolEnabled function doc - Number inline comments for each filter step (1-5) - Clarify FilteredTools error return is for future extensibility - Document that library consumers may need to surface recoverable errors Addresses review feedback on PR #1620 * Refactor GenerateToolsetsHelp() to use strings.Builder pattern Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com> --------- Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com> * Port functional changes from main to registry pattern Port three functional improvements from main branch: - GraphQL review comments grouped as threads (#1554) - get_file_contents description improvement (#1582) - create_or_update_file SHA validation fix (#1621) Adapted implementations to use the new registry pattern with: - BaseDeps for providing clients via ToolDependencies interface - deps.GetClient(ctx) and deps.GetGQLClient(ctx) patterns - Updated tests to use GraphQL mocks for review comments - Added SHA validation test cases for create_or_update_file * fix(e2e): Fix e2e test compilation and add rate limit handling - Fix DefaultToolsetIDs() type mismatch by using github.GetDefaultToolsetIDs() - Add waitForRateLimit() to check and wait for rate limits before each test - Add skip conditions for Copilot tests when Copilot isn't available - Use multi-line file content in TestPullRequestReviewCommentSubmit for multi-line review comments to work correctly - Improve error messages to include response details * fix(gists): Use proper GitHub API error handling for observability The gists.go file was using NewToolResultErrorFromErr for GitHub API errors, which breaks the error middleware tracking that the remote server uses for observability and incident detection. Changed API errors (client.Gists.List, Get, Create, Edit) to use ghErrors.NewGitHubAPIErrorResponse which properly: - Records errors in the context for middleware access - Preserves the response object for rate limit and status tracking - Maintains consistency with other tools that use this pattern This ensures production observability is maintained for Gist operations. * chore: Update server.json schema to 2025-12-11 - Update schema URL to latest version (2025-12-11) - Remove 'status' field (now managed by registry per 2025-09-29 changelog) * fix(get_file_contents): Restore correct implementation from #1582 The refactor incorrectly restructured the GetFileContents logic: - Move 'if rawOpts.SHA != "" { ref = rawOpts.SHA }' before GetContents call - Always call GetContents first (not conditionally based on path suffix) - Restore matchFiles helper function for proper fallback handling - Use matchFiles when Contents API fails or raw API fails This aligns with the improvements from PR #1582 that was merged into main. * Rename registry to inventory in comments Update remaining references to 'registry' in code comments to use 'inventory' consistently after the package rename. --------- Co-authored-by: Adam Holt <4619+omgitsads@users.noreply.github.com> Co-authored-by: Adam Holt <omgitsads@users.noreply.github.com> Co-authored-by: Adam Holt <oholt@github.com> Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com> |

fix: indent multi-line descriptions in generated docs
When tool parameter descriptions span multiple lines, the continuation lines now receive proper indentation to maintain markdown list formatting. This fixes the rendering issue where multi-line descriptions would break out of the parameter list structure. Fixes #1494 |
