- 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>
* 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 repos toolset instructions
* 1. Make sha optional (if not supplied - GetContents is used to retrieve original sha)
2. Instruct LLM to supply actual sha using git command and move instructions to tool description.
* Update toolsnaps and docs
* Better error handling
* Add tests
* Clearing resources in time
* Addressing review comments && checking etag
* Test fixes
* Improvements & refactoring of get_file_contents

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.

* Always include SHA in get_file_contents responses (#676)
* fix: Add SHA to get_file_contents while preserving MCP behavior (#595)
Enhance get_file_contents to include SHA information without changing
the existing MCP server response format.
Changes:
- Add Contents API call to retrieve SHA before fetching raw content
- Include SHA in resourceURI (repo://owner/repo/sha/{SHA}/contents/path)
- Add SHA to success messages
- Update tests to verify SHA inclusion
- Maintain original behavior: text files return raw text, binaries return base64
This preserves backward compatibility while providing SHA information
for better file versioning support.
Closes#595
* fix: Improve error handling for Contents API response
Ensure response body is properly closed even when an error occurs by moving
the defer statement before the error check. This prevents potential resource
leaks when the Contents API returns an error with a non-nil response.
Changes:
- Move defer respContents.Body.Close() before error checking
- Rename errContents to err for consistency
- Add nil check for respContents before attempting to close body
This follows Go best practices for handling HTTP responses and prevents
potential goroutine/memory leaks.
* revert changes to resource URI
