TIA_Portal_Openness_MCP
Open-source MCP server connecting AI tools to Siemens TIA Portal Openness API for PLC and ladder-logic automation workflows. MIT licensed, built in C#.
Overview
TIA_Portal_Openness_MCP is an open-source Model Context Protocol (MCP) server written in C# that bridges AI tools and intelligent workflows with the Siemens TIA Portal Openness API. By exposing TIA Portal automation capabilities through the MCP interface, it allows AI assistants, Vibe Coding environments, and custom agents to interact programmatically with PLC projects, ladder-logic, and industrial automation tasks. The project is hosted on GitHub under the MIT license and has attracted nearly 100 stars. It is aimed at independent developers, operations teams, and AI application builders who want to integrate large-language-model tooling with industrial automation engineering environments. No pre-built release binaries are currently indexed, so users are expected to build from source.
