Review Guard MCP Server
MCP server (review-guard-mcp) that lets AI agents work on GitHub PR reviews behind a safety boundary. The server holds the write-enabled GitHub token and exposes only review operations, so the agent never sees the token. What those operations are allowed to do is fixed at server start, not negotiable by the agent. Its 7 documented tools cover review, pending.
People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
