What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

install: node scripts/install.js

        require('child_process').execSync(`which ${command}`, { stdio: 'ignore' });

                result = subprocess.run(['java', '-jar', cfr_path, '--help'],
