mcp-clj

An implementation of the Model-Channel Protocol (MCP) in Clojure, designed to expose Clojure REPL functionality over an SSE transport.

mcp-clj is a Clojure implementation of the Model-Channel Protocol (MCP) defined by Anthropic. It provides both client and server components for MCP communication, with a specific focus on exposing Clojure REPL functionality. The project aims to maintain compatibility with Anthropic's MCP specification while providing a simple and reliable implementation.

Add mcp-clj as a dependency to your project.

1. Add the mcp-project as a dependency:

:deps {org.hugoduncan/mcp-clj
        {:git/url   "https://github.com/hugoduncan/mcp-clj"
         :git/sha   "replace with latest git sha"
         :deps/root "projects/server"}}

2. In the project, start the server:

(require 'mcp-clj.mcp-server.core)
(def server (mcp-clj.mcp-server.core/create-server {:port 3001}))

This will start the server on port 3001. You can then connect to the server using an MCP client.

To configure Claude Desktop to use mcp-clj, you need to use mcp-proxy.

In claude_desktop_config.json, add:

    "mcp-proxy": {
      "command": "mcp-proxy",
      "args": [
        "http://localhost:3001/sse"
      ],
      "env": {
        "API_ACCESS_TOKEN": "ABC"
      }
    }
