Polymarket Toolkit MCP Server

For anyone who wants to research Polymarket on their own - run the CLI yourself, or install skills for Claude / Cursor / OpenClaw and let AI run the tools. Read-only public APIs. No API keys. No signing. It runs locally over stdio via the published package.

People connecting finance tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Polymarket Toolkit

before you install - you'll need

AGENT_SKILLS_DIR

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add runesleo-polymarket-toolkit -- npx -y polymarket-toolkit-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "runesleo-polymarket-toolkit": {
      "command": "npx",
      "args": [
        "-y",
        "polymarket-toolkit-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
