Python REPL Server

MCPOpen SourceMIT43.0

by hdresearch • Tools & CLI

Provides a Python REPL over the MCP protocol, allowing agents to execute Python code with a persistent session.

Example Use Cases

1
Run and evaluate arbitrary Python code with persistent session state across multiple interactions.
2
Inspect, list, and manage in-memory variables created during an execution session.
3
Install Python packages at runtime to extend execution capabilities or test third-party libraries.

Description

This MCP server exposes a persistent Python REPL as tools usable via the MCP protocol. It supports executing arbitrary Python code, listing current session variables, and installing packages from PyPI. The session state (variables and imports) is preserved across calls unless explicitly reset, making it useful for multi-step workflows. It is lightweight to run (uses `uv` for execution) and includes configuration examples for integration with Claude Desktop.
