Revit AI: MCP servers and agent skills

How AI connects to Revit

An MCP server or skill can only do what Revit lets programs do. Revit exposes 4 automation interfaces:

• Revit API (.NET add-ins) (.NET): Almost every Revit server here is a C# add-in that runs inside Revit and passes calls from a separate MCP process over a local socket, named pipe or HTTP port. Because Revit only accepts API calls on its own thread, the add-in queues each request and wraps edits in transactions. The target framework changes with the release year: community READMEs build .NET Framework 4.8 add-ins for 2022–2024, .NET 8 for 2025–2026 and .NET 10 for 2027, which is why servers ship a separate build per year. Documentation
• pyRevit (Python): pyRevit is a free, GPL-licensed environment for writing Revit tools in IronPython, CPython or C#. Its Routes server exposes your own Python handlers over local HTTP, which is how the Demolinator and oakplank servers reach Revit without compiling a C# add-in; Routes has to be switched on in pyRevit's settings first. pyRevit is also the usual route for engineers who already script Revit and want to add their own tools. Documentation
• Dynamo (Other): Dynamo is the visual programming environment bundled with Revit, with Python Script nodes for anything the nodes don't cover. None of the MCP servers below drive Dynamo graphs directly, but the computational-design skill pack maps Grasshopper patterns to Dynamo equivalents, which helps when a Rhino workflow has to end in Revit. Documentation
• Automation API for Revit (APS) (REST API): Autodesk Platform Services runs a headless Revit engine in the cloud. You upload an AppBundle (a compiled add-in), define an activity and submit work items against files or Revit Cloud Models. Autodesk's sample MCP server uses this route, so it needs no desktop Revit but does need an APS app, credentials and a deployed activity. Documentation

What Autodesk offers

Autodesk publishes the Revit Public MCP Server as a separate add-on for Revit 2027 with the 2027.2 Update, downloaded from Autodesk Account under Extensions. It comes in Read (8 tools), Write (11) and Experimental (39) editions and is a technical preview whose tools may change before general release. Revit 2027's release notes mention using these tools from Autodesk Assistant. Autodesk's hosted Product Help MCP answers Revit documentation questions, and its developer team publishes Automation API samples on GitHub.

What you can do with Revit and AI

• Audit an open model by listing warnings, counting elements by category and level, and pulling parameter values such as fire ratings into a report before you change anything.
• Make bulk parameter edits on a filtered set of walls, doors or rooms, with a dry run or an approval step first on the servers that offer one.
• Set up documentation by creating levels, grids, sheets, plan and section views and schedules, then placing views on sheets and tagging rooms or walls.
• Model from a description, placing walls, floors, beams, ducts and pipes on given levels; one server also writes rebar with lap and anchorage rules.
• Check coordination with clash and clearance tests against linked models, then colour or isolate the offending elements in a view.
• Export views, IFC, gbXML, PDF or schedule data, and on cloud models create files or manage links through the Automation API without opening Revit.

Installing

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