# 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. But seems almost nothing is left from the original code.

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. All dependencies are automatically managed through the `pyproject.toml` file.

## 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 mcp_python
```

## 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"
      ]
    }
  }
}
```

## Available Tools

The server provides the following 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 using `uv`
   - `package`: Name of the package to install

4. `initialize_project`: Create a new project directory with timestamp prefix
   - `project_name`: Name for the project directory

5. `create_file`: Create a new file with specified content
   - `filename`: Path to the file (supports nested directories)
   - `content`: Content to write to the file

6. `load_file`: Load and execute a Python script in the current session
   - `filename`: Path to the Python script to load

## Features

- Persistent Python REPL session
- Automatic environment variable loading from `.env` files
- Package management using `uv`
- Project initialization with timestamped directories
- File creation and management
- Script loading and execution
- Comprehensive logging system
- Support for nested project structures

## Examples

Initialize a new project:

```python
# Create a new project directory
initialize_project("my_project")
```

Create and execute a script:

```python
# Create a new Python file
create_file("script.py", """
def greet(name):
    return f"Hello, {name}!"
""")

# Load and execute the script
load_file("script.py")

# Use the loaded function
print(greet("World"))
```

Install and use a package:

```python
# Install pandas
install_package("pandas")

# Use the installed package
import pandas as pd
df = pd.DataFrame({'A': [1, 2, 3]})
print(df)
```

List all variables:

```python
# Show all variables in the current session
list_variables()
```

Reset the session:

```python
# Use execute_python with reset=true to clear all variables
execute_python("", reset=True)
```
