MCP Command Executor is a server implementation that allows safe execution of system commands via the MCP protocol.
The MCP Command Executor is a robust server designed to execute system commands securely using the Model Context Protocol (MCP). It ensures security by only executing commands that are registered in an allowlist, preventing unauthorized or harmful command execution. The server is highly configurable, allowing users to specify allowed commands and environment variables through a YAML configuration file or environment variables. It supports global and per-command environment variables, providing flexibility in command execution. The server is built using Go and requires Go 1.24 or later, along with specific dependencies listed in its go.mod file. It offers detailed logging capabilities, which can be configured to be more verbose for debugging purposes. The server is designed to prevent shell injection by executing commands directly and validating them against a predefined allowlist. This makes it a secure choice for environments where command execution needs to be controlled and monitored.
