WAGO PLC MCP

An MCP server that allows AI assistants like Claude to interact with WAGO PLCs via the WDA REST API. It enables reading parameters, checking firmware versions, NTP status, and diagnostic LED states. The server is safe by default, refusing all writes until explicitly allowed, and blocks reboot, factory reset, and firmware methods.
