We built three open-source MCP servers that let any AI agent read, trace, and explain PLC and SCADA systems: • studio5000-mcp-server → full access to tags, routines, AOIs, cross-references • ignition-mcp-server → project parsing + live tag read/write • bridge-mcp-server → connects OPC tags ↔ PLC logic end-to-end Agent-agnostic. Air-gap capable. Runs entirely on your infrastructure. If you have an L5X file, you can get value from this in ~10 minutes. GitHub: https://lnkd.in/g2GM4gHk
