The server's core functionality involves executing arbitrary shell commands (`start_process`) and Node.js code (`node:local`) on the host system, and performing extensive filesystem operations (`read_file`, `write_file`, etc.). While there are important built-in mitigations like command blocking (`blockedCommands` config) and path validation (`allowedDirectories` config defaulting to user's home directory), the inherent power of the tools means a compromised AI agent could potentially execute malicious commands or access/modify files outside intended scope if `allowedDirectories` is set permissively. The `node:local` tool, in particular, executes user-provided Node.js code via temporary files, which is safer than `eval` but still allows arbitrary code execution. Users are warned when setting `allowedDirectories` to an empty array, which grants full filesystem access. Network requests are used for fetching remote files and telemetry, with error sanitization for privacy.
