NanoGPT MCP: Use NanoGPT inside Claude Code and Cursor

NanoGPT now supports the Model Context Protocol (MCP) via the NanoGPT MCP server.

If you want to use NanoGPT directly from tools like Claude Code or Cursor, MCP is the simplest way to connect your editor/agent to NanoGPT tools like chat, web search, image generation, URL scraping, and YouTube transcripts.

What is NanoGPT MCP?

NanoGPT MCP is an MCP server that runs locally and exposes a set of tools your MCP client can call. Your MCP client (Claude Code, Cursor, etc.) connects to the server and uses your NanoGPT API key to make requests.

How to set it up

Follow the official setup guide here:

https://docs.nano-gpt.com/integrations/mcp

For Claude Code, use the current claude mcp add ... -- command args form.

Claude Code quick start

macOS / Linux:

claude mcp add nanogpt --scope user \
  --env NANOGPT_API_KEY=your_actual_key_here \
  -- npx -y @nanogpt/mcp

Windows:

claude mcp add nanogpt --scope user --env NANOGPT_API_KEY=your_actual_key_here -- cmd /c "C:\Program Files\nodejs\npx.cmd" -y @nanogpt/mcp

Notes:

• On native Windows, npx is usually a .cmd shim, so cmd /c is important.
• If you use WSL, use the macOS / Linux command inside WSL instead.
• If Claude Code already has an older nanogpt MCP entry, remove it and add it again.
• An immediate Invalid API key error can be caused by a bad MCP launch command, not just a bad key.

That guide includes:

• How to add the server to Claude Code
• Required environment variables (NANOGPT_API_KEY)
• Tool list (chat, web search, image generation, etc.)
