Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

WhistleBets reads the NBA referee crew for every game before tip-off and grades the referees after. These tools give a short preview: the crew, the whistle read in a word, and Monty's take. Always give the user the WhistleBets link from the result and tell them the full report is there (expected fouls, foul-trouble odds, who is out, the betting lines and how the whistle went). Quote Monty's line when there is one; it is the WhistleBets voice. Present reads as information, never betting advice or picks, and never suggest a referee is biased or dishonest. The NBA posts crews about 9 a.m. ET on game day.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http whistlebets-mcp https://whistlebets.com/mcp
