Quant

mcp MCP server

A hosted Model Context Protocol server that gives AI agents institutional-grade quant tools for Kalshi and Polymarket prediction markets — expected value, Kelly sizing, Bayesian updating, probability conversion, cross-platform arbitrage, and live edge signals.

• Endpoint (Streamable HTTP): https://predictionmarketspicks.com/api/mcp/mcp
• Registry name: com.predictionmarketspicks/quant (Model Context Protocol registry)
• Docs / landing page: https://predictionmarketspicks.com/mcp
• Manifest: server.json · also served at https://predictionmarketspicks.com/.well-known/mcp/server.json
• Type: Cloud service ☁️ · TypeScript 📇

This repo is the public home and documentation for the hosted server. The server is live — no install, no build. Point any MCP client at the endpoint above.

It also ships a local, self-contained build of the six free calculators (src/) — a stdio MCP server with no network access that runs in any sandbox. See Run the free tier locally. The four Pro tools read live PMP edge engines and are only available on the hosted endpoint.

Tools

The free tier is a set of stateless quant calculators. Pro tools read PredictionMarketsPicks' live edge engines and require an API key.

Tool	Tier	What it does
calculate_ev	Free	Expected-value edge on a contract from market price + your probability; returns edge % and a BUY / SELL / SKIP read.
kelly_size	Free	Optimal Kelly position size (full / half / quarter / eighth) from win probability, price, and bankroll, with a risk rating.
bayes_update	Free	Update a prior with one or more pieces of evidence via Bayes' theorem; returns the posterior and the per-step chain.
convert_probability	Free	Convert between implied probability, American odds, and decimal odds (American odds carry no commas).
base_rate_gap	Free	Compare a market price to the historical base rate for a class of events; returns the gap in points + sample-size quality.
combo_edge	Free	Grade a same-game multi-leg combo: EV %, fair vs offered odds, and a negative-correlation-trap flag.
find_arbitrage	Pro	Cross-platform price gaps between Kalshi and Polymarket on the same sports contract (NBA, NHL, MLB, World Cup).
market_pulse	Pro	US macro-health composite (0–100) and regime, plus six category scores.
commodity_edge	Pro	Largest model edge on a Kalshi weekly-silver or twice-daily bitcoin strike, as a trade ticket (side, price, criterion, edge, tier, ¼-Kelly).
scan_mispricings	Pro	Polymarket contracts trading away from the PMP model, with direction, edge in points, and quarter-Kelly sizing.

All tool descriptions and outputs use prediction-market terminology (trader / position / contract / market analysis).

The free calculators work with no key. Pro tools require a PredictionMarketsPicks API key — see https://predictionmarketspicks.com/mcp.

Run the free tier locally

The six free calculators run entirely offline as a stdio MCP server — no key, no network. Useful for air-gapped agents, testing, or sandboxed hosts.

npm install
npm start          # stdio MCP server: 6 free tools
npm run smoke      # end-to-end self-test

Or with Docker:

docker build -t pmp-mcp-quant .
docker run --rm -i pmp-mcp-quant

Point a stdio MCP client at node src/index.js (or the container). For the full ten-tool experience including the live Pro edge engines, use the hosted endpoint above.
