Every Polymarket server is built by the community, so choose one by what you want your assistant to do. Read-only servers look up markets and wallets and need no keys. Trading servers place real USDC orders with your wallet's private key, so use a separate wallet with a small balance. If you only want to practise, a paper trading server runs on live order books with fake money.
Good for
- Traders who want Claude to scan markets, odds and order books before they bet
- Researchers checking a wallet's profit, win rate or forecasting record
- Developers testing a trading agent with paper money first
- Experienced traders who want an assistant to place real orders under set limits
Which Polymarket MCP server to use
Use Polymarket Toolkit to research markets and wallets with no keys, or Paper Trader to practise with fake money. Pick polymarket-mcp-server only if you want real orders, and start it in demo mode first.

Questions
Is there an official Polymarket MCP server?
No. Polymarket publishes SDKs and an agent skill that teaches assistants its APIs, but not an MCP server. Every server on this page is built by someone else.
Can an MCP server place real bets on Polymarket?
Yes. Trading servers such as polymarket-mcp-server and Polymarket Agent MCP place real USDC orders once you add your wallet's private key and Polymarket trading credentials. Without them, they stay read-only or simulated.
Is it safe to give a Polymarket MCP server my private key?
Only with a wallet you can afford to lose. The key sits in your assistant's config, and the server can spend whatever the wallet holds. Use a separate wallet with a small balance and set the server's order and exposure limits.
Do I need an API key to read Polymarket data?
No. Market prices, order books and public wallet activity come from Polymarket's public APIs. Read-only servers like Polymarket Toolkit work with no keys at all.
Can I practise trading without real money?
Yes. Polymarket Paper Trader gives you $10,000 of paper money against live order books with Polymarket's real fees. Polymarket Agent MCP also starts in a simulated preview mode until you switch it to live.
How do I keep a trading agent from spending too much?
Set the server's limits before you add a key. polymarket-mcp-server has per-order and total exposure caps and asks you to confirm orders above a dollar amount you choose. Polymarket's Session Keys, still in beta, let a separate signer trade for a Polymarket Deposit Wallet without being able to withdraw funds.
Why are my orders rejected?
You may be in a region Polymarket blocks. Polymarket rejects orders from blocked countries no matter which server sends them, and some regions can only close existing positions.
Why did my server's positions or trade history stop working?
Polymarket retired its old Data API on October 24, 2026. Servers that have not moved to the new version fail on positions, trades and activity. An open issue reports that polymarket-mcp-server's portfolio tools still use the old API, so check for an update before you rely on them.
