No API key. Remote server at https://mcp.chess.ceo/mcp or local via npx -y @chessceo/mcp.
Real-time tennis for ATP, WTA, Challenger and ITF — live scores, players, fixtures, model win-probability, and match-winner market prices. 12 read-only tools; a plan wall returns a plain-English explanation instead of a bare 403. Free tier, no card. npx -y livetennisapi-mcp
