Overview

What is TiaCommander?

TiaCommander is an MCP (Model Context Protocol) server that connects AI assistants to Siemens TIA Portal via the Openness API. It provides 16 tools and 166 actions covering the full TIA Portal project lifecycle, including session management, block operations, hardware configuration, cross-references, tag and watch tables, library operations, and online diagnostics. This server is intended for engineers and developers who work with Siemens TIA Portal and want to interact with it through AI assistants like Claude Desktop, Claude Code, or VS Code (Copilot).

How to use TiaCommander?

Download and extract the portable ZIP archive, then add TiaCommander to your MCP client configuration by specifying the full path to the TiaCommander.exe as the command. Once configured, the AI assistant can invoke the server’s tools to perform TIA Portal operations.

Frequently asked questions

What are the system requirements for TiaCommander?

TiaCommander requires Windows with .NET Framework 4.8 and Siemens TIA Portal V15.1 through V21 (tested on V19).

Which AI clients are supported?

Tested clients include Claude Desktop, Claude Code, VS Code (Copilot), Cursor, Windsurf, Codex CLI, and Gemini CLI.

How do I install TiaCommander?

Extract the portable ZIP archive to a folder (e.g., `C:\TiaCommander`) and add the server to your MCP client configuration using the full path to `TiaCommander.exe` as the command.

Does TiaCommander require a TIA Portal license?

The README does not explicitly address licensing. TIA Portal itself requires a valid license, and TiaCommander uses the Openness API, which may have its own licensing requirements as part of TIA Portal.

What transport protocol does TiaCommander use?

TiaCommander runs as a local command-line executable invoked by the MCP client, which implies standard input/output (stdio) transport as typical for MCP servers.
