About polymarket-agent-mcp
polymarket-agent-mcp is an MCP server published by the GitHub account demwick. Polymarket trading, market discovery, copy trading and backtesting — 48 MCP tools.
It runs on your own machine: your AI client starts it from the npm package polymarket-agent-mcp at version 1.7.0.
It asks for 4 secrets: POLY_PRIVATE_KEY, POLY_API_KEY, POLY_API_SECRET and POLY_API_PASSPHRASE. Give it a key with the least access that still works.
Version 1.7.0 was published on 7 August 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 1 warn, 0 fail, 1 info. How we check.
