🏏 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, career records, and live scores.

Built for MCP clients such as Claude Desktop and Cursor, so you can ask cricket questions in plain language and get answers computed from data instead of recalled from training.

No API key required. The archive is built from the freely available Cricsheet dataset, and live scores come from public endpoints.

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 17,907 matches (5.6M 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

Tool	What it does
cricket_win_probability	Win probability for any live or hypothetical match state
cricket_head_to_head	Career batter-vs-bowler record (balls, runs, dismissals, strike rate)
cricket_player_career	Career aggregates per format, men's and women's cricket
cricket_match_archive	Scorecard for an archived match, searched by teams / league / year
cricket_phase_stats	Batting and bowling split by powerplay, middle overs and death
cricket_venue_stats	Ground report: average first-innings score, chase win rate
cricket_leaders	League and season leaderboards for runs or wickets
cricket_team_form	A team's recent archived results
cricket_market_odds	Live prediction-market prices (Kalshi) beside this model's number
cricket_live_matches	Matches live and upcoming right now
cricket_explain_term	Any cricket term, with its baseball equivalent

All tools are read-only.

🚀 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:

OS	Config file
macOS	~/Library/Application Support/Claude/claude_desktop_config.json
Windows	%APPDATA%\Claude\claude_desktop_config.json
Linux	~/.config/Claude/claude_desktop_config.json

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

Restart the client and the cricket tools appear. That's the whole setup — on first use the server downloads the prebuilt archive once (~200 MB) into your OS cache directory (~/Library/Caches on macOS, ~/.cache on Linux, %LocalAppData% on Windows) and reuses it from then on. No account, no API key, no data pipeline to run.

The archive is generated from public Cricsheet data, so you can build your own rather than downloading ours:

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. Limited-overs-only archives work too — tools degrade gracefully when a format is absent.

💬 Example prompts

• "Who is favoured at 149 for 7 chasing 178 with three overs left?"
• "How does Kohli do against Bumrah in T20s?"
• "Does Grand Prairie Stadium favour chasing?"
• "Show me Pooran's death-overs record."
• "Who led the IPL run charts?"
• "What actually is a googly?"
• "What does the market think versus your model for Welsh Fire vs Southern Brave?"

⚙️ Configuration

Variable	Purpose
HISTORY_DB	Where the archive lives (default: your OS cache directory)
HISTORY_DB_URL	Override the archive download URL
HISTORY_DB_TOKEN	Bearer token, if that URL needs auth
HISTORY_QUERY_TIMEOUT	Query deadline, default 3s; raise for heavy leaderboards

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.
