MCP SERVER

Polymarket MCP

by joinQuantish

Trade Polymarket prediction markets from an agent: a managed Polygon wallet, live prices and order books, orders, positions and payouts.

Economic, Alternative & Prediction-Market Data
Summary
An agent that can hold a wallet and take a position.

This is the full trading path rather than a data feed — wallet custody, order placement and payout claiming all live here, which is why the encryption key and the database are yours and not a vendor's. Quantish has said it is winding down the platform, and the server is self-hosted precisely so it keeps running without them.

What it is

A self-hosted trading server for Polymarket. It manages the Polygon wallet, holds its key encrypted in your own database, and exposes market data, order placement, positions and settlement as calls. Most operations go through Polymarket's relayer, so they do not need MATIC for gas.

What you get
  • Wallet setup with Safe integration, deposit addresses, balances and wallet status
  • Private key import and export, and an API key requested for the trading account
  • Live price and order book for a market
  • Orders placed, listed, cancelled singly or all at once, and several submitted atomically
  • Positions read on-chain or synced, and USDC or shares transferred
  • Winnings listed and claimed once a market resolves
Requirements

You host it: a PostgreSQL database, a Polygon RPC endpoint, and an encryption key for the wallets it stores. Runs on any Node.js host.

Setup effort

One command plus a key — npx -y mcp-remote https://your-server.com/mcp --header x-api-key: YOUR_API_KEY, then supply credentials
