You can connect Claude Desktop to Kalshi prediction markets through a production-grade MCP server. It provides fast, authenticated access to search, analyze, and trade markets, plus real-time portfolio data and market details, enabling seamless interaction from your trading workflow.

How to use

This MCP server exposes a set of tools you can call from your MCP client to interact with Kalshi markets. You can search markets by keyword, retrieve market details and order books, view your portfolio and open positions, check trending markets by 24-hour volume, place limit orders, and fetch all markets within a series.

Get started with a simple setup

Configure the MCP connection in Claude Desktop so it can sign and send requests to Kalshi using your private key and API key. The server authenticates with RSA-PSS signatures and enforces rate limits to ensure reliable operation across multiple conversations.

Check your current balance and open positions to monitor exposure.
Search for markets related to topics you care about, and inspect prices and volumes.
Retrieve market details and depth in the order book to assess liquidity.
