### Description (declared)

# PyTorch Lightning MCP (Model Context Protocol)

An integration layer that exposes **PyTorch Lightning** through a structured, machine-readable API.

Intended for programmatic use by tools, agents, and orchestration systems.

## Features

* Structured training and inspection APIs
* Real PyTorch Lightning execution
* Explicit, config-driven behavior
* Safe model instantiation
* Stdio and HTTP servers
* Fully tested core logic
* Clean separation between protocol, capabilities, and transport

```

## Requirements

* Python 3.10 – 3.12
* PyTorch Lightning (compatible versions)
* uv (recommended)

## Installation (using uv)

### 1. Install uv (if not already installed)

```bash
curl -Ls https://astral.sh/uv/install.sh | sh
```

Restart your shell after installation.

Verify:

```bash
uv --version
```

### 2. Clone the repository

```bash
git clone https://github.com/<your-org>/lightning-mcp.git
cd lightning-mcp
```

### 3. Install dependencies

To install all dependencies (including server extras):

```bash
uv sync --all-extras
```

This will:

* create a local virtual environment
* install PyTorch Lightning and dependencies
* install HTTP server dependencies (FastAPI, Uvicorn)

No manual venv management is required.

## Usage

### Training (in-process)

```python
from lightning_mcp.handlers.train import TrainHandler
from lightning_mcp.protocol import MCPRequest

handler = TrainHandler()

request = MCPRequest(
    id="train-1",
    method="lightning.train",
   …
