What it can do

Creates, opens, converts, builds and exports Studio 5000 projects and changes the controller type.
Generates a compiling L5X project from a points list by splicing data types, tags and programs into a template exported from the SDK, then validates and diffs L5X files.
Reads and writes tags offline or online, sets comm paths, goes online, downloads, uploads and changes controller mode, with each of these gated behind confirm=true.
Simulates or publishes telemetry over MQTT, OPC UA and EtherNet/IP and runs FAT/SAT assertion suites.

Limitations

Needs Rockwell's LdSdkService running and two DOTNET_ROOT variables set; the author calls this the most common setup problem.
Created in October 2026 by an unaffiliated author, with no published release.

Install

Install the LDSDK Python wheel from your SDK installation and the requirements, then register run-mcp.cmd (which sets the environment variables and starts the server) as a stdio server in your MCP client.
