tia_portal_mcp_server

The server explicitly states it runs locally only, eliminating external network attack vectors for the server itself. It includes input sanitization for file paths and block names, and uses secure temporary file creation methods (e.g., `tempfile.mkdtemp`). Logs are correctly routed to `stderr` to avoid interfering with the MCP protocol output. However, the system relies on the Siemens TIA Portal Openness API, which is a Windows COM-based API. This introduces an inherent, external attack surface associated with TIA Portal itself and its necessary permissions (often administrative), which is beyond the direct control of this Python code. No explicit 'eval' or hardcoded sensitive credentials were found in the provided source.
