nit-mcp-server

An MCP server that exposes nit's code review agent as tools Claude can call directly, over Streamable HTTP.

Tools

• review_local_path calls nit-agent's POST /review with a local path and streams back the review

• review_github calls nit-agent's POST /review/github with a PR, commit, or file URL

Related MCP server: baby-gpt

Setup

1. Make sure nit-agent is running (default http://localhost:8080) and Ollama is up

2. cp .env.example .env.local and adjust NIT_AGENT_URL if nit-agent isn't on the default port

3. npm install

4. npm run dev

The MCP endpoint is now live at http://localhost:3000/api/mcp

Connecting Claude to it

Claude.ai (custom connector): Settings, Connectors, Add custom connector, paste http://localhost:3000/api/mcp

Claude Desktop or Claude Code (stdio bridge, since local URLs need a bridge):

{
  "mcpServers": {
    "nit": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "http://localhost:3000/api/mcp"]
    }
  }
}

Notes

• review_local_path sends an absolute path string, so nit-agent and this server need to run on the same machine, same as nit-cli's local review

• The GitHub token field is optional and only needed for private repos
