GitHub MCP Server 0.26.0

GitHub MCP Server gets a touch of gloss 💅

For clients that support icons (part of the newest MCP specification) we now provide them:

Main Features

🎨 Octicon Icons for Tools, Resources, and Prompts

MCP clients that support the new icons specification will now display GitHub's Octicon icons alongside tools and resources, making it easier to identify capabilities at a glance.

🏗️ Inventory Pattern Architecture

A new internal architecture introduces the Inventory pattern with builder, filtering, and per-request optimization. This lays groundwork for better performance and configurability, especially for remote server deployments.

🚩 Feature Flag Support & Consolidated Actions Toolsets

Added infrastructure for feature flag-based tool enablement, plus a consolidated actions toolset for better organization of GitHub Actions-related tools gated by a feature flag.

• --features cli flag or GITHUB_MCP_FEATURES via ENV.

🔧 Bug Fixes

• Fixed create_or_update SHA failures - Resolved issues where file updates could fail due to SHA mismatches
• Path parameter now optional - Fixed incorrect required parameter validation

📚 Documentation

• New Antigravity installation guide
• New tool renaming guide for handling deprecated tool names

GitHub MCP Server 0.26.0-rc.2

v0.26.0-rc.2 Release Notes

Fixes

• fix(get_file_contents): Restore correct implementation from #1582

  • Fixed control flow to resolve git reference SHA before calling GetContents API
  • Restored matchFiles helper function for proper fallback when files aren't found directly
  • Ensures proper URI construction with resolved SHA (e.g., repo://owner/repo/<sha>/contents/path)

• chore: Update server.json schema to 2025-12-11

  • Fixed MCP registry publish workflow by updating to non-deprecated schema
  • Removed status field (now managed by registry)

Summary

This pre-release fixes a regression in get_file_contents that was introduced during the registry refactor. The tool was returning empty responses because:

1. The resolved SHA wasn't being applied before the GitHub Contents API call
2. The matchFiles fallback logic was incorrectly restructured

Both issues are now fixed, restoring the behavior from PR #1582.

GitHub MCP Server 0.26.0-rc.1

Highlights

🏗️ Registry Pattern Refactoring

• Migrate context_tools to new ServerTool pattern (#1590)
• Migrate notifications.go to NewTool pattern (#1592)

These PRs are part of a larger refactoring effort moving all tools to a new ServerTool pattern with typed dependency injection. This improves code maintainability and enables better testability.

🐛 Bug Fix

• create_or_update_file - SHA is now optional; if not supplied, the tool automatically retrieves the original SHA (#1621)

📚 Documentation

• Add Antigravity installation guide (#1549)
• Add tool renaming guide (#1623)
