What it solves

This project provides a bridge between AI assistants (specifically Claude) and the Polymarket prediction market platform. It allows users to perform market research, analyze trading opportunities, and execute trades using natural language commands instead of manually interacting with the Polymarket interface.

How it works

It implements the Model Context Protocol (MCP), acting as a server that exposes 45 specialized tools to an AI agent. These tools interface with Polymarket's CLOB API, Gamma API, and WebSockets for real-time data. The server includes a safety layer that enforces order size limits, exposure caps, and liquidity checks to prevent AI-driven financial errors.

Who it’s for

Traders and developers who want to automate their prediction market strategies or use AI to analyze and manage their Polymarket portfolios.
