Revit Claude Connector

An open source bridge that lets Claude AI talk directly to Autodesk Revit using the Model Context Protocol.

Ask Claude things like:

"How many walls are in this model?" "List all families used on Level 2." "Export the structural elements to CSV."

Project Structure

| Folder | Description | |---|---| | src/Connector.Mcp.Server/ | Node.js MCP server — packaged as a .mcpb Claude Desktop extension | | src/RevitClaudePlugIn/ | C# WPF Revit add-in (plugin entry point and UI) | | src/BuiltInTools/ | 46 pre-built Revit tools (query, modify, export, visualise) |

Installation

See the Installation Guide for full instructions.

Quick start:

1. Download the latest release ZIP from Releases
2. Copy RevitClaudeConnector.addin and the RevitClaudeConnector\ folder to %APPDATA%\Autodesk\Revit\Addins\2026\
3. Install server/Revit.Claude.Connector.Mcp.Server.mcpb via Claude Desktop → Settings → Extensions

Building from Source

Requirements: .NET 8 SDK, Revit 2026

dotnet build src/RevitClaudeConnector.sln -c Release

Rebuilding the MCP server bundle:

npm install -g @anthropic-ai/mcpb
cd src/Connector.Mcp.Server
mcpb pack

Contributing

Contributions are welcome! There are three main ways to get involved:

• Enhance the built-in tools — improve or extend the 46 tools in src/BuiltInTools/ (better queries, new parameters, richer output, bug fixes).
• Publish custom tools — build and share your own tool packages so other users can drop them into their local Packages\ folder. See the Custom Tools guide.
• Improve the plugin itself — work on the MCP server, the Revit add-in, the UI, documentation, or anything else that makes the connector better.

Open an issue to discuss ideas, or submit a pull request directly.
