PLCWare MCP

PLCWare provides an MCP server that drives Siemens TIA Portal V21 via a local HTTP/JSON API. It allows AI assistants to create projects, configure hardware, write programs, compile, and download to PLCs, with mandatory human approval for downloads. The server bridges AI tools like Claude and Codex to the proprietary PLCWare app.
