Kalshi MCP Server: Add Prediction-Market Quant Tools to Claude, ChatGPT & Cursor

What’s in this video

This Tool Demos video walks through the PredictionMarketsPicks MCP server, which plugs the site's Kalshi and Polymarket quant tools directly into AI agents like Claude, ChatGPT, Gemini, Cursor, and Copilot. It shows the one-line setup command and connector URL needed to attach the server, and explains that the free tools let an agent run real math against live markets instead of guessing at contract prices.

Key points

• Add the server with a single Claude Code command or by pasting the connector URL into Claude Desktop, ChatGPT, Cursor, or Copilot using Streamable HTTP transport
• No scraping and no API key required for the free tools
• calculate_ev returns an expected-value edge on a contract with a BUY / SELL / SKIP signal
• kelly_size computes optimal position size for a bankroll at full, half, quarter, or eighth Kelly
• bayes_update chains evidence onto a prior to produce a step-by-step posterior
• Additional tools cover probability conversion, base-rate gap versus market price, same-game combo grading, and defense-adjusted NFL power ratings
