### Description (declared)

# lean-docker-mcp

Dockerized Lean4 execution environment for AI agents.

## Overview

This MCP server provides a safe, sandboxed Lean4 execution environment for LLM-powered agents. It allows agents to:

- Execute Lean4 code in isolated Docker containers
- Choose between transient or persistent execution environments
- Maintain state between execution steps

## Installation

### Requirements

- Docker must be installed and running on the host system
- Python 3.11 or later
- `uv` for package management (recommended)

### Install from PyPI

```bash
# Using uv (recommended)
uv pip install lean-docker-mcp

# Using pip
pip install lean-docker-mcp
```

### Install from Source

```bash
# Clone the repository
git clone https://github.com/artivus/lean-docker-mcp.git
cd lean-docker-mcp

# Install with uv
uv pip install -e .

# Or with pip
pip install -e .
```

## Quick Start

### Running the Server

The lean-docker-mcp server can be started directly using the module:

```bash
python -m lean_docker_mcp
```

This will start the MCP server and listen for JSONRPC requests on stdin/stdout.

## Components

### Docker Execution Environment

The server implements two types of execution environments:

1. **Transient Environment**
   - Each execution is isolated in a fresh container
   - State isn't maintained between calls
   - Safer for one-off code execution

2. **Persistent Environment**
   - Maintains state between executions
   - Variables and functions defined in one execution are available in subsequent executions
   - Suitable for interactive, stateful REPL-like sessions

### Tools

The server provides the following tools:

- **execute-lean**: Run Lean4 code in a transient Docker container
  - Takes `code` (required) parameter
  - Returns execution results

- **execute-lean-persistent**: Run Lean4 code in a persistent Docker container
  - Takes `code` (required) and `session_id` (optional) parameters
  - Returns execution results
  - Maintains state between calls

- **cleanup…
