Fit LLM MCP Server

Why a CLI? The "will it run?" question is born in the terminal - one line before ollama pull. No install, no tab-switching, and it reads your actual hardware with --detect instead of asking you to know your VRAM. It is available as a remote MCP endpoint.

Teams that want a hosted memory endpoint instead of running a local process. The project is written in JavaScript.

01 · Install Fit LLM

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add click6067-ship-it-fitllm-engine --transport http https://fitllm.run/api/mcp

Claude Desktop / Cursor / VS Code - add to config

    "click6067-ship-it-fitllm-engine": {
      "url": "https://fitllm.run/api/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
