At a glance

Type: MCP server
Works with: Revit, Rhino 3D & Grasshopper
How it connects: Drives a running copy of the tool
Access: Read-only or read-write (configurable)
Tool versions: Revit 2024 to 2027 (add-in built in CI; the README says no behaviour has yet been checked in a live Revit session)
Operating systems: Windows
Needs a Revit licence: Yes
Transport: Local (stdio)
AI clients documented: Claude Desktop, VS Code (GitHub Copilot), Cursor, Codex
Licence: GPL-3.0-or-later
Language: Python

What it can do

Reads warnings, elements and parameters straight away, and stages edits as a plan that you approve in the Revit panel before it runs.
Covers about 100 Revit tools for elements, views, sheets, schedules, exports and worksharing, plus QA/QC and report modules that work from saved snapshots.
The same hub reads IFC files through IfcOpenShell without Revit, and drives Rhino and Grasshopper and Speckle through separate providers.
A mock mode lists every tool and returns sample responses on any machine without Revit.

Limitations

Pre-release. The README says the add-in has only been compiled for each Revit year, not run against a live model, so treat Revit behaviour as unconfirmed and try it on a copy.
Dual licensed under GPL-3.0-or-later with a Revit linking exception, or a commercial licence.
Navisworks support is listed as in progress.
