5. Click Register application.
6. On the next page, you will see your Client ID. Save this for the next step.
7. Click Generate a new client secret and save the resulting secret (you will only see it once).

Configure Vercel Environment Variables

Once you have deployed the application to Vercel and registered your GitHub OAuth app:

2. Navigate to Settings > Environment Variables.
3. Add the following variables:
   • Key: GITHUB_CLIENT_ID

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.
