Shell Command

Summary

A shell command execution server for the MCP that allows AI assistants to run system commands in a controlled environment. Developed by egoist, this implementation provides a single tool for executing shell commands with built-in security features through an allowlist system. The server uses the ALLOWED_COMMANDS environment variable to explicitly permit specific commands, preventing unauthorized access to potentially dangerous system operations. It returns command results in YAML format with stdout, stderr, and exit code information. This implementation is particularly useful for scenarios where AI assistants need to interact with the local file system or run specific utilities while maintaining security boundaries.
