Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "polygon-io": {
      "url": "https://gateway.pipeworx.io/polygon-io/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1395+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Polygon Io data" })

The gateway picks the right tool and fills the arguments automatically.
