Polymarket MCP Server
A self-hosted MCP server that connects AI agents to Polymarket prediction markets on Polygon. It handles the full trading stack: wallet generation with Safe integration, gasless order placement through Polymarket's relayer, position tracking, and winnings claims. You get tools for placing and canceling orders, checking balances, transferring USDC and ERC-1155 shares, and swapping tokens via LI.FI. Requires PostgreSQL for wallet storage and a Polygon RPC endpoint. Wallets are encrypted at rest. Authentication uses API keys with optional HMAC signing for trusted bots. The Quantish team is no longer maintaining it, but the server runs independently once deployed to Railway, Fly.io, or any Node.js host.
