Autodesk’s official Revit MCP server lets an AI client such as Claude Desktop or Cursor read and, if you allow it, change a live Revit model. It is still a technical preview, and the setup has a few traps worth knowing before you start.
What’s new
Pick one of three servers. Autodesk ships three separate add-ons, and you only need one:
- Read-Tools: read-only. By our count of Autodesk’s tools table, 8 tools, such as querying the model, getting element data, selecting and showing elements, opening and exporting views.
- Write-Tools: everything in Read plus 3 tools that change the model: modify parameters, move and rotate elements.
- Experimental-Tools: everything above plus about 28 more, covering sheets, views, schedules, rooms, tagging, IFC and gbXML export, and deleting elements.
Requirements. Autodesk’s help pages list Revit 2027.2, running with a model open, and any AI client that supports local MCP servers. The server connects over STDIO on your own machine.
Setup steps. Install the add-on, then configure the client by hand. In Claude Desktop, turn on Developer mode, go to Settings > Developer > Edit Config and add the server entry to claude_desktop_config.json, pointing to Autodesk.RevitMcpServer.Stdio.exe in the folder of the variant you installed. Restart Claude Desktop, start Revit, open a model and test with the prompt “List the available Revit MCP tools.” Cursor uses %USERPROFILE%\.cursor\mcp.json and may need short Windows paths without spaces.
Why it matters
This is the first Autodesk-supported route for connecting general AI agents to Revit, as opposed to the built-in Autodesk Assistant. A few points are still unclear. Autodesk’s June announcement said clients would be configured automatically, while the current help says manual setup is required. Sources also differ on where to download the add-ons: Autodesk Account entitlements or the product updates and extensions page. Autodesk has not confirmed support for Revit 2027.3, released in September.
Start with Read-Tools on a copy of a project. Autodesk advises reviewing proposed changes and backing up the model before using write tools, and it notes that some AI clients need a paid plan for full MCP features.
