Use the professor inside ChatGPT or Claude

BJJ Professor is an MCP server. Add it once, sign in with Google, and your assistant can pull the position chapters, what coaches teach next, and timestamped clips from named coaches into any jiu-jitsu conversation, and it knows your game.

The server

One URL. Your assistant asks you to sign in with Google the first time (a free account is enough), then it can pull the chapters, the position map and clips, ask the professor about your specific problem, keep your focus areas and session logs, brief you before and after class, and read your analyzed rolls.

A direct request without signing in returns 401 Unauthorized. Your MCP client uses that response to start the OAuth connection flow.

Free accounts get two professor answers a month. Pro ($15/month) makes them unlimited and includes one roll a month of analysis. See plans

No account?

The chapters, position map, clips and example reviews are also available through the public REST API. No account or API key is needed. Start with the API guide and examples or the OpenAPI specification.

Finding the website in a chat does not connect its tools. To use the MCP tools, add and authorize the server first.
