What is the WhistleBets MCP server?

A free, read-only connector at https://whistlebets.com/mcp that lets AI assistants such as Claude, ChatGPT and Gemini look up tonight's NBA referee crews and the WhistleBets read while they answer you. The full reports stay on whistlebets.com.

Does it need an account or API key?

No. It is public and read-only. It cannot see your chats beyond the question your assistant sends, and it stores nothing.

Will it tell me what to bet?

No. It gives referee reads and grades with their sample sizes. It never makes picks.

For AI assistants

Ask your AI who's reffing tonight

Add WhistleBets to Claude, ChatGPT, Gemini or your code editor and ask who is reffing tonight. Your assistant gets the crew, the whistle read and Monty's take, with a link to the full report here.
