MCP Cricket

🏏 Cricket MCP Server

Cricket analytics for Claude Desktop, Claude Code, Cursor and any other MCP client — a calibrated win-probability model, 22,479 archived matches, and live prediction-market prices.

A Model Context Protocol server that gives AI assistants real cricket knowledge: a calibrated win-probability model, a ball-by-ball archive of 22,000+ matches, live prediction-market prices, career records, and live scores.

Ask cricket questions in plain language and get answers computed from data rather than recalled from training.

⚡ Add it in one step

It is hosted. There is nothing to install, download, build or configure.

https://cricketfornoobs.com/mcp

Paste that into your client's connector settings and you are done.

No account, no API key, no data pipeline. Read-only.

Prefer to run it on your own machine? See Quick start below: same tools, one static binary.

💬 Things to ask it

• "Who's winning the India match right now, and what does the model say?"
• "What's the score in the Minor League Cricket game, and who's favoured?"
• "Who is favoured at 149 for 7 chasing 178 with three overs left?"
• "How does Kohli bat against Bumrah in T20s?"
• "What does the market think versus your model for Welsh Fire vs Southern Brave?"
• "How does Bumrah get his wickets — bowled, caught, lbw?"
• "What's Rashid Khan's dot-ball percentage in T20s?"
• "Is Kohli better batting first or chasing?"
• "Who does Rohit Sharma score most of his runs with?"
• "Does Grand Prairie Stadium favour chasing?"
• "Show me Pooran's death-overs record."
• "What actually is a googly?"

The same win model runs in production at cricketfornoobs.com, a live cricket explainer for American sports fans. This server exposes the analytics side of it to any MCP client.

✨ What makes this different

Most sports MCP servers wrap a scores API. This one ships analysis:

• Win probability from a fitted model — logistic regression per format and innings over 10,847 matches (3.4M ball states), with pre-match Elo ratings. Held-out log loss 0.42 (T20 chases) / 0.40 (ODI chases); ~91% accurate on confident calls. It knows that 149/7 chasing 178 is not the same story as 149/2.
• Ball-by-ball archive — 22,479 matches and 11.4M deliveries across T20, ODI/List-A, Tests and domestic multi-day cricket.
• Career and matchup records — batter-vs-bowler head-to-heads, phase splits (powerplay / middle / death), venue reports, league leaderboards.
• Baseball translations — every cricket term explained through its closest baseball equivalent, for newcomers to the sport.

🛠️ Tools

All tools are read-only.

Minor League Cricket data. ESPN does not carry the league, so its fixtures and scores come from Kalshi's public live data: the schedule, each game's score and state, and Kalshi's market beside it. That feed has no ball-by-ball commentary and names no batters or bowlers, so cricket_minor_league cannot say who is batting, who took a wicket or what happened on a given ball. A market figure appears only when Kalshi's book is a real price, and the model prices only the chase. The hosted server's cricket_minor_league_info does name players: it draws on CricClubs scorecards and results, and on Wikipedia's season articles (CC BY-SA 4.0), which is why that data stays on the hosted server.

🚀 Quick start

1. Install

One static binary, no runtime, no interpreter, no dependencies.

go install github.com/asaraog/mcp-cricket/cmd/cricket-mcp@latest

Or download a prebuilt binary for macOS (Apple silicon or Intel), Linux (x86-64 or arm64) or Windows from Releases.

Register it with Claude Code:

claude mcp add cricket -- ~/go/bin/cricket-mcp

2. Or configure a desktop client

Add the server to your client's config — for Claude Desktop:

{
  "mcpServers": {
    "cricket": {
      "command": "/ABSOLUTE/PATH/TO/cricket-mcp"
    }
  }
}

Restart the client and the cricket tools appear. Live scores, the win model, market prices and the glossary work as they are. The archive tools need the ball-by-ball database, which is not in the binary.

3. The archive

The database is built by the asaraog/cricket-history-data workflow from public Cricsheet data and published there as a release asset, history-full.db.gz (206 MB). That release is private. With HISTORY_DB_TOKEN set to a GitHub token that can read it, the server resolves the latest release on first use, downloads the archive once into your OS cache directory (~/Library/Caches on macOS, ~/.cache on Linux, %LocalAppData% on Windows) and reuses it from then on; when a later release replaces the asset, the next start downloads the new one. Without a token the download fails and the archive tools say the archive is missing.

Building it yourself needs no token:

curl -O https://cricsheet.org/downloads/all_json.zip
python3 scripts/histgen.py all_json.zip history.db

Then point HISTORY_DB at the result. A file you built is opened as it is and never replaced by a download. Limited-overs-only archives work too: tools degrade gracefully when a format is absent.

scripts/histgen.py is the same script the workflow runs. Since 2026-10-06 its deliveries table carries wide and noball columns, so balls faced leave out wides and a bowler's balls leave out wides and no-balls, as a scorecard counts them. An archive built before that has neither column; the server reads it as before, counting every row as a ball.

Since 2026-10-07 its matches table also carries a gender column, male or female as Cricsheet records it. cricket_leaders and cricket_team_form filter on it. Older archives (the v1 file and the 2026-10-06 rebuild) still work: without the column, a game's gender is read off its event name, which says "Women" for Cricsheet's women's events.

⚙️ Configuration

Live-score tools work without any archive; archive tools report clearly when the database is missing rather than inventing an answer.

📊 About the model

The win model is fitted offline, not guessed at runtime. Features are match state (runs, wickets, balls remaining, required rate), pre-match Elo, and a wickets × required-rate interaction — because thin batting hurts far more when the asking rate is steep. Calibration is measured by wickets in hand: within about one point across most of the range.

Par is per ground. A first-innings score only means something relative to what the ground usually yields, so the innings-one segments are fitted against a table of 371 grounds and 7 leagues rather than one global constant. Real pars run from 153.7 to 172.5 by league alone, and further by ground. Pass venue (and league) to cricket_win_probability and the same 80/2 at ten overs is 47% at Chinnaswamy and 60% at Newlands. Without a venue it falls back ground → league → global, which costs about 0.006 of held-out log loss.

It cannot see injuries, weather, pitch reports or team news.

📈 Markets

cricket_market_odds reads public prices from Kalshi, a CFTC-regulated US exchange where contracts settle at $1 and a price in cents is the implied probability. Put beside cricket_win_probability, the gap between the two is the edge a trader would be claiming.

This is informational only — read-only market data, no account, no orders, no advice. The model cannot see injuries, weather or team news, which is often exactly why it disagrees with the market. Event contracts are legal in some jurisdictions and not others.
