gemini mcp add --scope user servers-for-revit cmd -- /c npx -y mcp-server-for-revitWhat it does
mcp-servers-for-revit links an MCP client to a running copy of Autodesk Revit. It comes in three parts: the npm package mcp-server-for-revit, which is the MCP server the client starts over stdio; a C# add-in loaded by Revit; and a command set of C# DLLs that the add-in calls to do the actual work through the Revit API. The server passes each tool call to the add-in over a WebSocket and returns what Revit sends back.
The tools cover reading the open project (active view, its elements, the current selection, family types, material takeoffs, model statistics, filtered element queries), creating elements (doors and windows, walls and beams, floors and roofs, grids, levels, rooms, dimensions, beam framing systems), changing or deleting elements, colouring them by a parameter value, tagging walls and rooms, and exporting room data. send_code_to_revit runs C# written by the client inside a template with access to the open Revit document. A few tools keep project and room records in a local SQLite file for later queries.
The project is a fork, kept by the same GitHub organisation, of its earlier revit-mcp server, with extra tools added. At v1.0.0 the server loads every file in its tools folder; three of them (modify_element.ts, search_modules.ts and use_module.ts) are empty, so the package exposes the 26 tools the README lists and no more.
What it needs
| Runtime | Node.js 18+ |
|---|
Windows with Autodesk Revit 2020 to 2026 installed and licensed, and Node.js 18 or newer for the npm server. The add-in and command set must be copied into %AppData%\Autodesk\Revit\Addins\<version>\ from the release ZIP for your Revit year. Revit must be open, and the commands you want must be switched on and saved under Settings on the add-in's ribbon tab.
Limits
It works only while Revit is open with the add-in loaded; the server reaches the add-in at localhost port 8080, a fixed address in its code, and gives up on a call if the connection is not made within 5 seconds (ConnectionManager.ts). Commands not enabled in the add-in's Settings are unavailable. The SQLite store (revit-data.db) is written inside the installed package's own folder, so with npx it sits in the npx cache rather than with your project, and can be lost when that cache is cleared (db.ts). Revit itself runs only on Windows.
Who it suits
Suits Revit users and BIM developers on Windows who want an assistant to query a live model, place standard elements, tag and colour views, or run one-off C# against the Revit API without writing an add-in. It changes the open model and can run arbitrary code with no review step in the server, so it fits people who keep backups and check what is sent. The same organisation's mcp-server-for-revit-python, which we also list, runs through pyRevit instead and, by its README, shows model-changing requests and Python code in Revit for review before they run. Anyone without a Revit licence has no use for either.
