# tiny-agents

[tiny-agents](https://huggingface.co/blog/python-tiny-agents) offers a minimal pattern for building tool-using agents. A small Python loop connects an MCP client to tools from MCP servers. Hugging Face Spaces work as MCP servers. Find more compatible Spaces on the [Hub](https://huggingface.co/spaces?filter=mcp-server).

Create a config file that points to your local model and the tool server. This example uses an image generation [Space](https://evalstate-flux1-schnell.hf.space/).

```json
{
    "model": "Menlo/Jan-nano",
    "endpointUrl": "http://localhost:8000",
    "servers": [
        {
            "type": "sse",
            "url": "https://evalstate-flux1-schnell.hf.space/gradio_api/mcp/sse"
        }
    ]
}
```

Run the agent with your config.

```bash
tiny-agents run path/to/your/config.json
```

Ensure `transformers serve` is running in the background. The agent will use your local model to run the image generation tool.

```bash

I have generated an image of a cat on the moon using the Flux 1 Schnell Image Generator. The image is 1024x1024 pixels and was created with 4 inference steps. Let me know if you would like to make any changes or need further assistance!
