Polar as Model Context Protocol (MCP)

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 has MCP support built into the Polar TypeScript SDK.

​

How does it work?

You need a MCP-capable Agent environment to use Polar as an MCP server. A few of them are Claude and Cursor.
