Polymarket MCP Server
Let Claude Code or Cursor agents discover markets, read odds, and execute trades on Polymarket through a self-hosted MCP bridge.
Overview
Polymarket MCP Server is a Build-phase MCP integration that lets AI agents interact with Polymarket prediction markets through a self-hosted stdio server.
What is this MCP server?
- Self-hosted MCP server scoped to Polymarket prediction markets
- Designed for AI agent workflows rather than manual browser trading
- stdio transport for local Claude Code, Cursor, and compatible MCP clients
- Repository: joinQuantish/polymarket-mcp (version 0.1.0 in server metadata)
- Server schema version 0.1.0 in published metadata
- Source repository: github.com/joinQuantish/polymarket-mcp
What problem does it solve?
Agents cannot safely trade or research Polymarket unless you rebuild market and order APIs as one-off scripts for every project.
Who is it for?
Indie builders prototyping agent-driven Polymarket research, alerting, or execution with their own keys and infra.
Skip if: Teams that need a hosted SaaS terminal, non-agent manual trading UIs, or builders who will not run or secure a self-hosted MCP process.
What do I get? / Deliverables
After you register the server locally, your agent can call Polymarket-oriented MCP tools from Claude Code, Cursor, or other MCP clients using your hosted instance.
- Registered stdio MCP server in your agent config
- Agent-callable tools for Polymarket market operations
- Repeatable local trading or research loop without per-session custom scripts
Recommended MCP Servers
Journey fit
Prediction-market trading is wired into the product as an external API integration during the build phase, not a launch or operate monitoring concern. MCP registration and Polymarket API wiring belong on the integrations shelf alongside other agent-facing connectors.
How it compares
MCP market connector for agents, not a prediction-market web app or a general finance analytics skill.
Common Questions / FAQ
Who is Polymarket MCP Server for?
Solo and indie developers who use Claude Code, Cursor, or similar MCP clients and want agent-accessible Polymarket workflows on hardware they control.
When should I use Polymarket MCP Server?
