The natural shape is a chained instruction — connect, open the project, export or compile, close, disconnect — and the project's own examples read exactly like that. Two prerequisites bite people before anything works: the `TiaPortalLocation` variable and Openness group membership are both Windows-side setup that TIA Portal will not prompt you about.
A Visual Studio Code extension that registers an MCP server for Siemens TIA Portal V20. It connects to a running TIA Portal instance through Siemens Openness, so an agent in Copilot chat can work with the project directly.
- Connect to a running TIA Portal instance and open a project file
- Read back the project structure, including as markdown you can paste into documentation
- Export all blocks from a PLC software target to a folder in your workspace
- Export all types from the same PLC software target
- Compile a named PLC software target
- Close the project and disconnect when the session is done
Windows with Siemens TIA Portal V20 installed and running, Siemens.Openness, and .NET Framework 4.8. The `TiaPortalLocation` user environment variable must point at the Portal V20 install directory, and your Windows account must be in the `Siemens TIA Openness` group. In VS Code you need GitHub Copilot with MCP enabled; the extension writes the server entry for you via its “TIA Portal: Add MCP Server Configuration” command.
