Polar over Model Context Protocol (MCP)

Extend the capabilities of your AI agents with Polar’s MCP Server

Supercharge your AI agents with Polar as a Model Context Protocol (MCP) server.

What is MCP?

MCP is a protocol for integrating tools with AI agents. It can greatly enhance the capabilities of your AI agents by providing them with real-time data and context.

Polar offers a remote MCP server that you can connect to from most AI clients.

How does it work?

You need a MCP-capable agent environment to use Polar over MCP. A few of them are Claude Desktop and Cursor.

Connecting to Polar MCP

When you can specify a MCP URL, use https://mcp.polar.sh/mcp/polar-mcp.

If you have to specify a command, use:

{
  "mcpServers": {
    "Polar": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp.polar.sh/mcp/polar-mcp"]
    }
  }
}

Cursor

In .cursor/mcp.json, add:

  "mcpServers": {
    "Polar": {
      "url": "https://mcp.polar.sh/mcp/polar-mcp"

    }
  }
}
