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"
    }
  }
}

​
Windsurf

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

​
Codex

Add the following to your ~/.codex/config.toml: 
[mcp_servers.polar]
command = "npx"
args = ["-y", "mcp-remote", "https://mcp.polar.sh/mcp/polar-mcp"]

​
Claude Code

Run the following command: 
claude mcp add --transport http "Polar" "https://mcp.polar.sh/mcp/polar-mcp"

​
ChatGPT

MCP is only available for paid users in beta on ChatGPT web, by enabling Developer Mode. Once Developer Mode is enabled, go to Settings → Connectors and add the MCP server using https://mcp.polar.sh/mcp/polar-mcp.

​
Claude Desktop

Go to Settings → Connectors and click Add custom connector. Name it “Polar” and add https://mcp.polar.sh/mcp/polar-mcp as the server URL. Save, and click Connect to connect to your Polar organization.
