Step 1 — Install the Revit Plugin

Important — Unblock the ZIP before extracting

Windows marks files downloaded from the internet as blocked, which will cause Revit to throw an exception when loading the plugin. Before extracting, right-click the ZIP file → Properties → check Unblock at the bottom → click OK.

1. Open File Explorer and navigate to your Revit add-ins folder. Replace 20XX with your Revit version:

   %APPDATA%\Autodesk\Revit\Addins\20XX\

   (Paste that path directly into the File Explorer address bar)

2. From the ZIP, open the folder that matches your Revit version:

   • Revit 2025 or above → use Revit2025Plus/
   • Revit 2024 or below → use Revit2024/

3. Copy both of the following from your chosen folder into the add-ins directory:

   • RevitClaudeConnector.addin
   • RevitClaudeConnector\ (the entire subfolder)

   The final layout should look like:

   %APPDATA%\Autodesk\Revit\Addins\20XX\
   ├── RevitClaudeConnector.addin
   └── RevitClaudeConnector\
       ├── RevitClaudePlugIn.dll
       ├── BuiltInTools.dll
       └── ...

4. Launch (or restart) Revit. A Claude Connector tab will appear in the ribbon.

Step 2 — Install the MCP Server

1. Open Claude Desktop.
2. Go to Settings → Extensions (or drag and drop the .mcpb file onto the Claude Desktop window).
3. Select server/Revit.Claude.Connector.Mcp.Server.mcpb from your chosen variant folder and confirm the installation.
4. Restart Claude Desktop when prompted.

In Claude Desktop, you can now ask Claude to query and manipulate your Revit model.

NOTE: Once both the plugin and the MCP server are installed, open Revit and click the Status button in the Claude Connector ribbon tab. The status should read Running.

Troubleshooting

Problem	Fix
Plugin doesn't appear in Revit	Verify the .addin file and RevitClaudeConnector\ folder are both in the correct Addins\20XX\ directory
MCP server not connecting	Ensure Claude Desktop has been restarted after the extension was installed
Revit shows a security warning	Click Always Load to trust the add-in
