"This MCP is like having a teammate with perfect memory of every PR ever written." — Example Review

Overview

GitHub PR Review Context MCP gives AI assistants institutional review memory.

Instead of generic feedback, reviews are informed by historical reviewer comments, recurring quality patterns, and repository-specific standards from your own PR history.

Core Value

• Improves review consistency across teams and repositories.
• Reduces repeated reviewer feedback on known issues.
• Integrates with any MCP-compatible client and multiple LLM providers.

Key Capabilities

Capability	What It Delivers
Historical review retrieval	Semantic search across prior PR comments and review summaries
Context-aware AI review	Feedback grounded in repository-specific review behavior
Grounded code generation	Generate new code based on past commits, comments, and style
Team rules generation	Auto-generate .cursorrules / CLAUDE.md from repo history
Smart repository readiness	Auto-detect indexed state and index on demand
Flexible storage modes	Permanent (disk) and temporary (in-memory) indexing options
Portable inference layer	Switch LLM providers using environment configuration only

🚀 Quick Start

🚀 Zero-Setup (uvx / pipx / npx)

The fastest way to use the server. No cloning required. Just run one of these commands directly in your terminal or use them in your IDE's MCP settings:

[!TIP] Don't clone this repo to get AI rules! Once installed, run generate_repo_rules inside YOUR project to automatically create .cursorrules or CLAUDE.md tailored to your own team's PR history.

Using uvx (Recommended for speed):

uvx github-pr-context-mcp

Using pipx (Recommended for stability):

pipx run github-pr-context-mcp
# Or install permanently:
pipx install github-pr-context-mcp

Using npx (Smithery bridge):

npx -y @smithery/cli run github-pr-context-mcp

---

⚠️ Manual Installation (Git Clone / Advanced)

[!WARNING] Running from a git clone is only recommended for developers contributing to this project. For general use, please use the pipx method above.

If you have cloned the repository for development:

1. Create a virtual environment: python -m venv .venv
2. Activate it and install: pip install -e .
3. Run automatic setup: python scripts/install_clients.py

For full configuration (Cursor, Claude Desktop), see the Quick Start Guide.

---

[!IMPORTANT] 🚀 USE THE OFFICIAL PACKAGE: This project is now on PyPI. To ensure seamless updates and zero configuration friction, do NOT git clone.

Recommended Install:

pipx install github-pr-context-mcp

Or run instantly with: uvx github-pr-context-mcp

🛠️ Usage Modes: Solo vs. Team

This MCP server is built to scale from a single machine to an entire engineering organization.

👤 Solo Developer (Local Mode)

Best for: Privacy, local-first control, and zero hosting costs.

• How it works: Run via uvx, pipx, or a local git clone.
• Storage: ChromaDB stays on your local machine.
• Security: Your GitHub Token and LLM keys never leave your device.
• Setup: See Quick Start.

🤝 Team Collaboration (Hosted Mode — UPCOMING)

Best for: Scaling team-wide PR standards and centralized infra.

• How it works: One deployment on Render (Coming Soon) shared by the whole team.
• Isolation: Strict Gmail-based namespace isolation (driven by SQLite). User A's indexed data is mathematically invisible to User B.
• Economics: Pooled LLM credits and a single shared indexing server.
• Setup: See Deployment Guide.

🌟 Zero-Friction Setup (Upcoming)

If your team has hosted this MCP on Render, you do NOT need to git clone or install anything. Just drop this snippet into your IDE:

"github-pr-context": {
  "type": "sse",
  "url": "https://YOUR-RENDER-URL.onrender.com/mcp",
  "headers": {
    "Authorization": "Bearer YOUR_TOKEN"
  }
}

That's it. If your IDE supports native MCP SSE connections, you are immediately connected to the secure Render deployment.

🛠️ Troubleshooting

• "command not found": Use absolute paths in your configuration. Run github-pr-context-mcp config to get your exact path.
• "PermissionError: [WinError 32]": The binary is locked by a running process. Close Claude/Cursor, run taskkill /F /IM github-pr-context-mcp.exe, then retry the upgrade.
