Gitctx

About

Gitctx is an open-source MCP (Machine Code Protocol) server designed to give AI coding tools and IDE assistants precise, current access to GitHub repositories. It serves as a specialized alternative to proprietary solutions like Amp's Librarian, enabling agents to explore code, issues, pull requests, commits, releases, and more. By offering focused GitHub exploration primitives and maintaining stateful repository context, gitctx optimizes iterative code understanding workflows, delivering high-signal information for sophisticated AI-driven development tasks.

Key Features

• Targeted GitHub repository discovery and selection
• Comprehensive codebase navigation (tree, list, read, search, branch switching)
• In-depth issue and pull request exploration with filters and metadata
• Analysis of commits, blame, releases, and repository statistics
• In-memory API caching to reduce repeated GitHub API calls
• 9 GitHub stars

Use Cases

• Summarize unresolved review feedback on a specific pull request.
• Map an authentication flow end-to-end with relevant file references for codebase understanding.
• Produce a release-readiness brief for a specific feature, analyzing code paths, open issues, merged PRs, and commit churn.
