betbetter-mcp

An MCP server that gives any AI assistant access to sports model win probabilities and fair odds across nine sports — no API key, no sign-up, free to use.

Tools

Example

"What does the model think about the Geelong game this weekend?"

{
  "game": "Geelong Cats @ Collingwood Magpies",
  "market": "Head to Head",
  "selection": "Geelong Cats",
  "modelProbabilityPct": 54.9,
  "fairOdds": 1.82,
  "confidence": "LEAN"
}

What this does not do

It publishes no bookmaker prices. There is no bookmaker name, market price or implied probability anywhere in the feed, and none is planned — the underlying odds data is licensed under terms that allow publishing derived work but not redistributing the feed. Everything here is the model's own output, so it cannot tell you where to bet or at what price.

Configuration

Responses are cached upstream for 15 minutes. Feeds are empty out of season — that is expected, not an error.

Responsible gambling

18+. Gambling involves risk and most people lose money. These are model estimates for research, not betting advice, and not a guarantee of any outcome. A selection rated 70% is meant to lose roughly three times in ten.

If gambling is causing you harm: Gambling Help Online (AU) or 1-800-GAMBLER (US).
