nano-gpt-mcp

An MCP (Model Context Protocol) server for NanoGPT — giving you access to 700+ AI models for text, image, video, and audio generation directly from Claude Code or any MCP-compatible client.

What is NanoGPT?

NanoGPT is a pay-as-you-go AI gateway that provides access to models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and many more — all through a single API key. No subscriptions required.

Setup

1. Get a NanoGPT API Key

Sign up at nano-gpt.com and get your API key from the dashboard.

2. Install

git clone https://github.com/mageaustralia/nano-gpt-mcp.git
cd nano-gpt-mcp
npm install

3. Configure Claude Code

Add to your ~/.claude/settings.json to make it available globally (all projects):

{
  "mcpServers": {
    "nano-gpt": {
      "command": "node",
      "args": ["/path/to/nano-gpt-mcp/server.mjs"],
      "env": {
        "NANO_GPT_API_KEY": "your-api-key-here"
      }
    }
  }
}

Or add to a project-specific .claude/settings.json for per-project use.

4. Restart Claude Code

The MCP server will be available after restarting Claude Code.

Usage Examples

Chat with any model

"Use nano_chat to ask GPT-4o what the best sorting algorithm is for nearly-sorted data"

"Ask DeepSeek R1 to solve this math problem using nano_chat"

"Use nano_chat with google/gemini-2.5-flash to review this code snippet"

Generate images

"Use nano_generate_image with hidream-i1-fast to create a product photo of a laptop on a white background"

"Generate an image with gpt-image-1.5: a watercolor painting of a coastal town at sunset"

"Use nano-banana to generate a logo for a coffee shop called 'Bean There'"

Generate videos

"Use nano_generate_video with kling-v26-pro to create a 5-second video of ocean waves"

"Generate a video with wan-wavespeed-25: a timelapse of flowers blooming"

List models and pricing

"Use nano_list_models to show me all image models"

"List video models on nano-gpt"

"Search for 'llama' in nano-gpt text models"

Check balance

"Check my nano-gpt balance"

How it works

The MCP server translates tool calls into NanoGPT API requests:

• Chat: OpenAI-compatible /v1/chat/completions endpoint

• Images: /v1/images/generations endpoint (returns URLs or base64)

• Videos: /v1/video/generations endpoint

• Models: /v1/models, /v1/image-models, /v1/video-models, /v1/audio-models
