OpenModelica MCP servers and AI agent skills

How AI connects to OpenModelica

An MCP server or skill can only do what OpenModelica lets programs do. OpenModelica exposes 2 automation interfaces:

• OMPython (Python): OMPython is OpenModelica's Python session handler. It talks to the OpenModelica compiler over ZeroMQ, either starting omc as a child process or connecting to one already running, and its ModelicaSystem class compiles a model, sets parameters, simulates and linearises it into A, B, C and D matrices. A runner mode replays precompiled models without omc. Documentation
• Scripting API (.mos and omc) (Command line): The compiler also takes scripting commands written in Modelica syntax: loadModel loads a library, checkModel reports variable and equation counts, and buildModel translates a model to C and builds a simulation executable. The modelica-skills gate runner calls omc for its build, unit-checking and energy-balance gates, finding it on PATH, in standard install folders or in a running Docker container. Documentation

What Open source offers

The OpenModelica website and user's guide cover the compiler, OMPython and the scripting API, but no AI assistant, agent or MCP server as of this check. The only AI integration found is modelica-skills, a community plugin that uses OpenModelica as its simulation engine for verification gates.

What you can do with OpenModelica and AI

• Interview you about a model's purpose, physics, ranges and sources, then split the work into tasks and build one task at a time.
• Run build, unit-checking and energy-balance gates on a model through omc and record what each check showed.
• Tie every correlation in a model to a cited source and check the transcription.
• Calibrate parameters and diagnose a model that won't simulate or gives the wrong answer.
• Review a model change independently and keep a credibility record that says no more than the evidence shows.

Installing

The listings here document setup for Claude Code and Google Antigravity. Install steps, copied from each project's own documentation, are on each listing's page. Most OpenModelica integrations run on your own computer next to OpenModelica, so you need OpenModelica installed and licensed on the same machine unless the listing says otherwise.
