Clerk MCP Server

⚠️ Warning: This project is in active development and subject to rapid changes. Features and APIs may be modified frequently. If you have feedback or workflows you'd like to see supported, please get in touch via [email protected]

Model Context Protocol (MCP) is a standardized protocol for managing context between large language models (LLMs) and external systems or services like Clerk.

Clerk's MCP server allows you to use any MCP Client (Claude Desktop, Cursor, Windsurf and many others) to use natural language and your LLM to accomplish things with Clerk.

Setup

Requirements

• Node.js >= v18.0.0
• MCP Client
• Clerk Secret Key - get this from the Clerk project dashboard:

⚠️ Security Warning: Never share or commit your Clerk Secret Key. If exposed, immediately rotate it in your Clerk Dashboard. Add it to your .gitignore file and use environment variables in production.

Installation

Installation will vary depending on your client, but in most cases you'll need to add the JSON below to your MCP config file. Be sure to insert your Clerk API token.

{
  "mcpServers": {
    "Clerk": {
      "command": "npx",
      "args": ["@clerk/clerk-mcp@latest"],
      "env": {
        "CLERK_API_KEY": "YOUR CLERK API KEY",
        "ALL_TOOLS": "false",         // Optional

      }
    }
  }
}

Features

This project supports tools for all Clerk API endpoints by setting the ALL_TOOLS to "true". It also supports some prompt workflows tested in Cursor which allow you to quickstart Clerk applications.
