What it does

Connects an AI assistant to a secure shell environment, allowing the execution of a specific, allowlisted set of shell commands. It prevents arbitrary code execution by avoiding shell-string interpretation and enforcing strict command whitelisting.

Tools

execute_command: Runs a whitelisted shell command with support for stdin, stderr, and stdout capture.
