Prediction Markets MCP Server — FAQ
What is the PredictionMarketsPicks MCP server?
It is a Model Context Protocol (MCP) server that exposes PredictionMarketsPicks quant tools as callable functions inside any MCP-compatible AI agent — Claude, ChatGPT, Gemini, Cursor, or Copilot. Instead of scraping the site, an agent can call the expected-value, Kelly sizing, Bayesian update, odds-conversion, and base-rate tools directly and get structured numbers back. It uses the Streamable HTTP transport at https://predictionmarketspicks.com/api/mcp/mcp.
Is the MCP server free?
Yes — the Phase 1 calculator tools (EV edge, Kelly sizing, Bayesian update, probability/odds conversion, base-rate gap) are free with no API key, rate limited per IP. Live-data edge tools (mispricing scans, arbitrage gaps, commodity edge) are the paid Pro tier ($14.99/mo) and require a PredictionMarketsPicks API key passed by the agent.
How do I connect Claude or ChatGPT to it?
Add the remote MCP server URL https://predictionmarketspicks.com/api/mcp/mcp to your client. In Claude Desktop or Claude.ai, add it as a custom connector. In ChatGPT, add it under connectors / developer mode. In Cursor or Copilot, add it to your MCP settings JSON with a streamable-http (HTTP) transport pointing at that URL. No key is needed for the free calculator tools.
What can the tools actually do?
calculate_ev returns the percentage edge and a BUY/SELL/SKIP signal for a contract given its price and your probability. kelly_size returns the optimal position size for a bankroll. bayes_update chains evidence into a posterior probability. convert_probability moves between implied probability, American odds, and decimal odds. base_rate_gap compares a market price to a historical base rate. Every result links back to the full interactive tool on the site.
Are these prediction markets the same as a sportsbook?
No. Kalshi and Polymarket are CFTC-regulated event-derivative exchanges, not sportsbooks. The MCP tools treat every contract as a probability problem — expected value, calibration, and position sizing — the same quant framework a bond or options desk runs. Educational analysis, not financial advice.
