### Description (declared)

# Python REPL MCP Server

> This is a fork of [hdresearch/mcp-python](https://github.com/hdresearch/mcp-python), a Python REPL server for MCP protocol.

This MCP server provides a Python REPL (Read-Eval-Print Loop) as a tool. It allows execution of Python code through the MCP protocol with a persistent session.

## Setup

No setup needed! The project uses `uv` for dependency management.

## Environment Variables

The server supports `.env` file for environment variables management. Create a `.env` file in the root directory to store your environment variables. These variables will be automatically loaded and accessible in your Python REPL session using:

```python
import os

# Access environment variables
my_var = os.environ.get('MY_VARIABLE')
# or
my_var = os.getenv('MY_VARIABLE')
```

## Running the Server

Simply run:

```bash
uv run src/python_repl/server.py
```

## Usage with Claude Desktop

Add this configuration to your Claude Desktop config file:

```json
{
  "mcpServers": {
    "python-repl": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/python-repl-server",
        "run",
        "mcp_python"
      ]
    }
  }
}
```

The server provides three tools:

1. `execute_python`: Execute Python code with persistent variables

   - `code`: The Python code to execute
   - `reset`: Optional boolean to reset the session

2. `list_variables`: Show all variables in the current session

3. `install_package`: Install a package from pypi

## Examples

Set a variable:

```python
a = 42
```

Use the variable:

```python
print(f"The value is {a}")
```

List all variables:

```python
# Use the list_variables tool
```

Reset the session:

```python
# Use execute_python with reset=true
```
