The File System server implements robust path validation checks (e.g., `path.resolve().startswith(ALLOWED_DIR.resolve())`) for all file operations (read, write, search, stats). This is crucial and effectively prevents directory traversal attacks, limiting file access and modification to the `test_files` directory (or a user-configured directory). The `write_file` tool is exposed, allowing an agent to create/modify files within the allowed directory, which is an intended but powerful capability. The Calculator server is purely computational, using standard Python `math` functions and explicit arithmetic operations without `eval` or dynamic code execution, making it inherently safe. There are no obvious hardcoded secrets or network risks beyond standard MCP (stdin/stdout) communication. The `factorial` tool has a maximum input limit (n<=20) to prevent resource exhaustion.
