wago-plc-mcp-server

This MCP server connects Claude and other AI assistants to WAGO PLCs. You ask a question in plain English. The assistant gets the answer from the PLC. You do not need scripts or parameter IDs.

Overview demo

Quick start

You need Claude Desktop and a PLC that your computer can reach on the network.

  1. Download wago-plc-mcp-server-<version>.mcpb from the latest release.

  2. In Claude Desktop, go to Settings → Extensions.

  3. Drag the .mcpb file onto the window.

  4. In the form, enter the PLC IP address and the WBM password. Then save the form.

  5. Ask Claude: "List my PLCs".

If the installer does not start on Windows, or if you have many PLCs, see Claude Desktop and Claude Code.

Safe by default

  • The server only reads. It refuses all writes until you select Allow writes and method calls.

  • The server refuses reboot, factory reset, and firmware methods. An administrator can allow one exact method.

  • An audit log records each write and each method call.
