Python REPL MCP 服务器

此 MCP 服务器提供了一个 Python REPL（读取-求值-打印循环）工具。它允许通过 MCP 协议以持久会话的方式执行 Python 代码。

设置

无需设置！该项目使用uv进行依赖管理。

运行服务器

只需运行：

uv run src/python_repl/server.py

与 Claude Desktop 一起使用

将此配置添加到您的 Claude Desktop 配置文件：

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

该服务器提供了三种工具：

execute_python带有持久变量的 Python 代码
- code ：要执行的 Python 代码
- reset ：可选布尔值，用于重置会话
list_variables ：显示当前会话中的所有变量
install_package ：从 pypi 安装包

示例

设置变量：

a = 42

使用变量：

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

列出所有变量：

# Use the list_variables tool

重置会话：

# Use execute_python with reset=true
