Summary
Gives Claude a sandboxed environment to execute Python, JavaScript, and shell commands through the Model Context Protocol. The server exposes a REPL interface that lets Claude run arbitrary code snippets and see the output without touching your local system directly. Reach for this when you want Claude to prototype algorithms, test data transformations, or validate logic in real time during a conversation. It's part of the broader NIRA toolkit from pachote, which includes nine other MCP servers for screen capture, process management, and multi-model orchestration. Installs via pip and plugs into Claude's MCP config with a simple Python module command.
