MCP Server with Clerk & Next.js

A minimal example of an MCP server endpoint using Next.js and Clerk for authentication.

Getting started

• Run pnpm i to install dependencies.
• Create a Clerk application, then toggle on the Dynamic client registration option in the OAuth applications page in the Clerk Dashboard.
• Run cp .env.example .env.local and copy your Clerk API keys from the API keys page in the Clerk Dashboard into the .env.local file
• Run pnpm run dev to start the app
• You should be able to connect to it now from any client that supports the latest version of the MCP spec. A cursor configuration is provided as a test.

Connecting to the server

To test in cursor, for example, add the following config to your mcp config file:

"mcp-clerk-next": {
  "url": "http://localhost:3000/mcp"
}

Examples of other clients coming soon!
