## What it does

This tool collects pull request history from GitHub, indexes it in ChromaDB, and returns raw JSON records to your agent. Code generation and reasoning stay with the IDE model. Background indexing begins with `ensure_repo_ready`. Progress is tracked with `get_index_stats`.

Authentication relies on GitHub App Device Flow. Credentials stay inside your operating system keyring, so personal access tokens are unnecessary. The server runs on Python 3.10 or newer. ChromaDB 0.5.0 breaks on NumPy 2, which makes `numpy<2.0>` mandatory.

Past PR data is untrusted material. The agent should never execute historical comments as system instructions.

## Requirements
- Needs: Python and uv (commands run via uvx)
- Works with: GitHub

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- retrieve past discussion records and code decisions from pull request history
- index repository pull requests into a local ChromaDB store
- provide historical background to the agent during code reviews
- authenticate with GitHub via Device Flow without managing personal access tokens

## Example prompts
- Check our GitHub connection status using `get_github_connection_status`
- Index pull requests for `owner/repo` with `ensure_repo_ready`
- Search PR history to find why this function was modified
