Python Local REPL Server

Example Use Cases

• 1

  Execute Python code in persistent sessions and preserve interpreter state across multiple calls.

• 2

  Run arbitrary expressions or statements and capture stdout/stderr output alongside execution results.

• 3

  Programmatic access to past REPL interactions or audit trails via a repl:// URI as plain-text session history.

Description

This MCP server exposes a session-based Python REPL over the MCP protocol, allowing callers to execute expressions and statements in persistent named sessions. It captures stdout/stderr, maintains separate state per session, and exposes each session's history as text/plain resources via a custom repl:// URI. The project includes instructions for building, publishing, and debugging (including using the MCP Inspector) to support development and integration.
