plctap runs on your own machine — the client starts it, so there is no endpoint to ping. 143 installs a week from pypi. Last commit 13 Sep 2026.
Agent-PLC MCP Server: read & diagnose Modbus / FINS / MELSEC / S7 / IEC 104 / ENIP / OPC UA PLCs.
Today is the operative word: we check plctap every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
