### Description (declared)

# mcp-run-python-code
Python interpreter, MCP server, no API key, free. Get results from running Python code.

## Overview

This MCP server provides tools for running Python code, installing packages, and executing Python files. 
It can be easily integrated with MCP clients, including Claude and other LLM applications supporting the MCP protocol.

## Features

- Execute Python code in a safe environment
- Install Python packages using pip
- Save Python code to files and run them
- Run existing Python files
- Return specific variable values from executed code
- Error handling and debugging support

## Installation

### From pip
You can install the MCP Run Python Code Server using `uv`:

```bash
uv pip install mcp-run-python-code
```

Or using pip:

```bash
pip install mcp-run-python-code
```

### From source
```bash
git clone https://github.com/shibing624/mcp-run-python-code.git
cd mcp-run-python-code
pip install -e .
```

## Usage
### Python Demo
```python
from run_python_code import RunPythonCode

tool = RunPythonCode(base_dir='/tmp/tmp_run_code/')

# 示例1：基本代码执行
result = tool.run_python_code("x = 10\ny = 20\nz = x * y", "z")
print(f"结果: {result}")  # 输出: 结果: 200

# 示例2：保存并运行文件
result = tool.save_to_file_and_run(
    file_name="calc.py",
    code="a = 5\nb = 15\nc = a + b",
    variable_to_return="c"
)
print(f"结果: {result}")  # 输出: 结果: 20

# 实例3：安装python包
result = tool.pip_install_package("requests")
print(f"结果: {result}")
```

### Running as a standalone MCP server

Run the server with the stdio transport:

```bash
uvx mcp-run-python-code
```

or

```bash
uv run mcp-run-python-code
```

or 

```bash
python -m mcp-run-python-code
```

Then, you can use the server with any MCP client that supports stdio transport.

### Integrating with Cursor

To add the weather MCP server to Cursor, add stdio MCP with command:

```bash
uvx mcp-run-python-code
```
