OpenStudio MCP servers and AI agent skills

OpenStudio has an official MCP server from the team that develops it, OpenStudio-MCP, with 150+ tools and bundled Claude Code skills for building, editing and simulating models through the OpenStudio SDK and EnergyPlus. Two community servers add a lighter OSM inspector and a Canadian NECB fork. All run in Docker on your model files, without the OpenStudio Application; the official image pins OpenStudio 3.11.0.

  • Includes US DOE (NatLabRockies, formerly NREL)'s official server.
  • 3 MCP servers and 1 agent skill listed.

How AI connects to OpenStudio

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

  • OpenStudio SDK (Ruby, Python, C#, C++) (Python): The SDK is a C++ library with Ruby, Python and C# bindings for creating and editing OSM models, translating them to EnergyPlus IDF and running simulations. Reference documentation is published per release, 3.11.0 being current at this check, with a 4.0.0 alpha listed. OpenStudio-MCP calls the SDK inside its container, and its get_versions tool reports the OpenStudio, EnergyPlus and Ruby versions in use. Documentation
  • Measures and the command line interface (Command line): Measures are Ruby or Python scripts that change a model in a repeatable way, and the SDK runs measure-based workflows only through its command line interface. The Building Component Library hosts shared measures. OpenStudio-MCP can write, test and apply measures and download them from BCL, and it treats measure code as untrusted, running it in a sandbox. Documentation

What US DOE (NatLabRockies, formerly NREL) offers

The National Laboratory of the Rockies (formerly NREL), which maintains the OpenStudio repository, publishes OpenStudio-MCP under the same GitHub organisation and describes it in a 2026 SoftwareX paper. The OpenStudio SDK documentation itself describes no in-app AI assistant. A PNNL package, openstudio-ai, is on PyPI but its source repository needs a sign-in, so it isn't listed here.

What you can do with OpenStudio and AI

  • Create a ten-zone office with VAV reheat, run an annual simulation and report EUI and unmet heating hours.
  • Swap an HVAC system, for example VAV to VRF heat pumps, and compare energy use before and after.
  • Apply an ASHRAE 90.1 typical building template or baseline system to an existing model.
  • Write a measure, such as setting all lighting to 8 W/m2, test it, apply it and compare results.
  • Import a Revit gbXML export, repair geometry defects and assign standards space types.

Installing

The listings here document setup for Claude Code, Claude Desktop, Codex, Cursor, Gemini CLI, VS Code, VS Code (GitHub Copilot) and Windsurf. Install steps, copied from each project's own documentation, are on each listing's page. Most OpenStudio integrations run on your own computer next to OpenStudio, so you need OpenStudio installed and licensed on the same machine unless the listing says otherwise.

Questions

Is there an official OpenStudio MCP server?

Yes. OpenStudio-MCP is published by NatLabRockies, the GitHub organisation that also maintains the OpenStudio SDK, and it ships with workflow skills for Claude Code.

Can Claude build an OpenStudio model from a description?

Yes. OpenStudio-MCP creates buildings from type, floor area and aspect ratio, adds constructions, loads and HVAC from typical templates, and runs EnergyPlus on the result.

Why can't the server see a file I attached in the chat?

The tools only see files in the folders mounted into the Docker container. Put the model in the folder mapped to /inputs and refer to it by that path.

Does OpenStudio-MCP work with Canadian NECB rules?

Not out of the box. A community fork, openstudio-mcp-necb, adds NECB prototype and ruleset tools with pinned NRCan and NRC standards.

AI-generated models, drawings and results must be checked by a qualified engineer before use.
