A good mcp server for TIA Portal, to link TIA Opennes, PLCSim Advanced and more to your AI Agent

A high-performance, persistent Model Context Protocol (MCP) server providing AI coding agents (such as Google Antigravity, Claude Desktop, Cursor, and VS Code) with direct programmatic control over Siemens TIA Portal V21 and S7-PLCSIM Advanced V8.0.
Equipped with 62 specialized industrial automation tools, this server bridges generative AI with deterministic industrial hardware and software—enabling automated PLC logic authoring, model-based architecture ingestion (Draw.io / PlantUML / Mermaid), automated design-to-HMI pipelines (Figma to WinCC Unified), live simulation memory I/O, and automated Hardware-in-the-Loop (HIL) sequence verification with telemetry report generation.
Architectural Tenets: 1. Always-On Connection Persistence (connexion must stay): TIA Portal and project instances are heavy COM entities requiring significant startup time. TiaManager and PlcSimManager maintain live handles in memory so every AI turn executes with sub-second latency without reloading the project. 2. Dual-Transport Flexibility: Standard MCP stdio for agent runners, alongside a concurrent HTTP/SSE daemon (port 5001) for web interfaces, live telemetry dashboards, and multi-agent orchestrators. 3. Clean-Room Assembly Loading: Dynamically resolves Siemens assemblies from local installation paths (PublicAPI\V21\net48\ and PLCSIMADV\API\8.0\), avoiding unauthorized binary redistribution while ensuring 100% binary compatibility with Siemens updates.
