Sports Probabilities MCP
An MCP server that gives AI assistants Monte Carlo probabilities for the NFL, MLB and 17 soccer leagues, plus a model-versus-market comparison against live Kalshi prices.
Ask in plain language from Claude, ChatGPT or Cursor and get a computed number back — not an estimate the model made up.
The server runs on Apify: https://apify.com/commodus67/sports-probabilities-mcp
This repository holds the documentation and the registry manifest (server.json). The implementation lives in the Actor above.

Tools
| Tool | Purpose |
|---|---|
get_team_probabilities | One team's full probability set, current record, projected finish and ranking |
get_league_probabilities | A whole league ranked by probability rather than by points or record |
compare_model_vs_market | Model against live Kalshi prices: edge, expected value after fees, fractional Kelly stake |
run_scenario | A fresh simulation under custom model assumptions, with movement analysis |
get_probability_history | How a team's probability moved across the season, from archived runs |

How it works
Each answer comes from one of three published Monte Carlo Actors that take live standings and the remaining schedule, play out the rest of the season thousands of times, and count how often each outcome happens. The MCP server calls those Actors and caches the result — it does not reimplement the simulation, so an answer here never disagrees with the same query made directly against the API.
Every response carries the date and the source of the run it came from.
Pricing
Pay per event, billed through Apify. From $50.00 per 1,000 probability reads. Full pricing on the Actor page.
Note
This is statistics and simulation. It is not betting advice, and it does not produce picks.
