Usage

This server conforms to the Model Context Protocol (MCP).

Clients will discover the endpoint via: GET https://your-app.vercel.app/mcp (which redirects/rewrites to /api/mcp).

OAuth flow should be initiated by the client to GitHub, specifying your Client ID, and then returning to the /api/auth/callback endpoint which will exchange the code for an access token.
