- Remove Sizes field from octicons.Icons() to fix compatibility with older MCP clients
- Older clients like Cursor expect sizes to be a string, not an array
- The 2025-11-25 MCP spec changed sizes from string to array
- Omitting the optional Sizes field makes icons compatible with all clients
- Update tests and toolsnaps to reflect the change
Fixes#1644
Co-authored-by: SamMorrowDrums <4811358+SamMorrowDrums@users.noreply.github.com>
This refactor addresses performance issues in per-request server scenarios
where creating ~90 handler closures per request was causing latency.
Changes:
- Add ContextWithDeps, DepsFromContext, MustDepsFromContext to dependencies.go
- Add NewServerToolWithContextHandler, NewServerToolWithRawContextHandler to inventory
- Convert all 89 tool handlers from closure pattern to direct context-based deps
- Update all tests to inject deps into context before calling handlers
- Mark old NewServerTool and NewServerToolFromHandler as deprecated
The new pattern:
- Before: func(deps) handler { return func(ctx, req, args) { use deps } }
- After: func(ctx, deps, req, args) { use deps }
Dependencies are now injected into context once (via ContextWithDeps) and
extracted by NewTool internally before passing to handlers. This eliminates
closure creation on the hot path for remote servers.
* 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
Add NewGitHubAPIStatusErrorResponse helper function to properly track
GitHub API errors when the API call succeeds but returns an unexpected
HTTP status code (e.g., 404, 422, 500).
Previously, these errors were returned via utils.NewToolResultError which
bypasses the context-based error tracking used by the remote server's
error_categorizer.go for observability metrics. This resulted in 100%
tool call success rates in observability even when errors occurred.
The fix adds a new helper function that:
1. Creates a synthetic error from the status code and response body
2. Records the error in context via NewGitHubAPIErrorResponse
3. Returns the MCP error result to the client
Updated all tool files to use the new pattern for status code errors:
- pullrequests.go: 12 fixes
- repositories.go: 18 fixes
- issues.go: 10 fixes
- notifications.go: 6 fixes
- projects.go: 5 fixes
- search.go: 3 fixes
- search_utils.go: 1 fix
- gists.go: 4 fixes
- code_scanning.go: 2 fixes
- dependabot.go: 2 fixes
- secret_scanning.go: 2 fixes
- security_advisories.go: 4 fixes
Total: ~69 error paths now properly tracked.
Note: Parameter validation errors (RequiredParam failures) and internal
I/O errors (io.ReadAll failures) intentionally continue to use
utils.NewToolResultError as they are not GitHub API errors.
* refactor: separate ServerTool into own file with HandlerFunc pattern
- Extract ServerTool struct into pkg/toolsets/server_tool.go
- Add ToolDependencies struct for passing common dependencies to handlers
- HandlerFunc allows lazy handler generation from Tool definitions

- Infrastructure ready for incremental tool migration
* refactor(search): migrate search tools to new ServerTool pattern
Migrate search.go tools (SearchRepositories, SearchCode, SearchUsers,
SearchOrgs) to use the new NewTool helper and ToolDependencies pattern.
- Functions now take only TranslationHelperFunc and return ServerTool
- Handler generation uses ToolDependencies for typed access to clients
- Update tools.go call sites to remove getClient parameter
- Update tests to use new Handler(deps) pattern
This demonstrates the migration pattern for additional tool files.

* 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:

- 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

- 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.

OpenAI strict mode requires the `properties` field to be present in
object schemas, even when empty. The jsonschema library uses omitempty
which causes empty maps to be omitted during JSON serialization.
This change uses json.RawMessage to bypass the library's serialization
and explicitly include `"properties": {}` in the output.
Fixes#1548

* Add state metadata fields to get_discussion tool
Fixes#1303
The get_discussion tool was missing important state metadata that's
already available in get_issue. Added four fields to provide complete
discussion status information:
- state: Current discussion state (OPEN/CLOSED)
- isAnswered: Whether the discussion has an accepted answer
- answeredAt: Timestamp when answer was provided
- answerChosenAt: Timestamp when answer was selected
Changed GetDiscussion to return a map instead of github.Discussion
struct since the go-github library doesn't include all these fields
in its type definition. This approach is consistent with other
functions in this codebase (ListDiscussions, GetDiscussionComments).
All tests pass and linter checks pass.
* Fix Discussion field mappings based on GitHub GraphQL API
Changes:
- Replace 'State' (doesn't exist) with 'Closed' (Boolean)
- Remove 'AnsweredAt' (doesn't exist)
- Keep 'IsAnswered' (verified to exist in GitHub GraphQL API)
- Use 'AnswerChosenAt' for answer timestamp
Updated both implementation and tests to match actual GitHub GraphQL schema.
All tests passing.
