概要

What is Clerk MCP Server Template?

A production-ready template for building Model Context Protocol (MCP) servers that integrate Clerk authentication with Cloudflare Workers. It provides a complete OAuth 2.0 flow, Durable Objects for session state, and KV storage for temporary OAuth sessions. Designed for developers who want to connect their existing Clerk-authenticated applications to Claude AI through secure MCP tools.

How to use Clerk MCP Server Template?

Clone the repository, run npm install, configure environment variables (CLERK_SECRET_KEY, CLERK_PUBLISHABLE_KEY, APP_URL) in a .dev.vars file, create a KV namespace with Wrangler, update the namespace ID in wrangler.jsonc, and start the development server with npm run dev. Requires Node.js 22+, a Clerk account, a Cloudflare account with Workers enabled, and an existing application using Clerk for authentication.

FAQ from Clerk MCP Server Template

What does Clerk MCP Server Template do vs alternatives?

It bridges your existing Clerk-authenticated application with Claude AI through MCP tools. Unlike generic MCP servers, it provides a ready-made OAuth flow and session management tailored for Clerk, reducing integration effort.

What are the dependencies/runtime requirements?

You need Node.js 22+, a Clerk account with API keys, a Cloudflare account with Workers enabled, and an existing application that uses Clerk for authentication.

Where does data live?

OAuth session data is stored temporarily in Cloudflare KV. MCP session state is managed in Durable Objects. All application data remains in your existing Clerk-powered application.

What transports/auth are supported?

The server uses SSE (Server-Sent Events) transport and OAuth 2.0 authentication with Clerk. JWT tokens are used for API requests, and state parameters are protected with HMAC signatures.

Are there known limits?

The README does not list hard limits, but the template relies on Cloudflare Workers and Durable Objects – scale and performance depend on those platforms. OAuth sessions in KV expire automatically.
