Server Kalshi MCP Server

An MCP server that gives Claude Code and other agent harnesses a first-class interface to Kalshi. It is built for end-to-end trading: browse markets, research them, read the exact settlement rules (including pulling the contract-terms PDFs), and execute trades - all through MCP tools. It runs locally over stdio via the published package.

People connecting finance tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
