shell-command-mcp
The shell-command-mcp is an MCP server designed for executing shell commands. It operates in a Node.js environment and is implemented in TypeScript. A key feature is the use of the ALLOWED_COMMANDS environment variable, which allows you to control which commands can be executed, enhancing security by restricting execution to specific commands. It can be easily launched from the command line and is capable of integration with applications like ChatWise.
