Python REPL MCP Server
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.
Running the Server
Simply run:
Usage with Claude Desktop

The server provides three tools:
execute_python
: Execute Python code with persistent variablescode
: The Python code to executereset
: Optional boolean to reset the session
list_variables
: Show all variables in the current sessioninstall_package
: Install a package from pypi
