How to Set Up and Use Revit
RevitMCP bridges Autodesk Revit and AI assistants by running a local MCP server inside Revit via the pyRevit framework. It exposes 44 tools covering project metadata, element selection, property reads and writes, graphic overrides, schedule management, family queries, and multi-step workflow execution. BIM engineers and architects use it to query and manipulate live Revit models through natural language, dramatically accelerating tasks like parameter updates, schedule creation, and element filtering that would otherwise require manual UI navigation.
Prerequisites
- Autodesk Revit 2022 or later installed on Windows
- pyRevit 5.x installed and configured with Revit
- Python 3.x available through pyRevit's bundled IronPython or CPython engine
- An MCP-compatible client such as Claude Desktop or Claude Code
- Git for cloning the extension into the pyRevit extensions folder
Clone the extension into the pyRevit extensions directory
The folder name must end with .extension for pyRevit to discover it automatically at Revit startup. Run this command in PowerShell or Command Prompt.
git clone https://github.com/oakplank/RevitMCP.git "%APPDATA%\pyRevit\Extensions\RevitMCP.extension"Reload pyRevit inside Revit
Open Revit, go to the pyRevit tab, and click Reload. RevitMCP will appear as a new tab in the Revit ribbon. Click the RevitMCP button to start the local server.
Configure the server settings file
The server writes a settings file on first run. Edit it to choose between 'mcp' surface mode (for direct MCP clients) or 'web' mode, and to set the host and port.
// %USERPROFILE%\Documents\RevitMCP\user_data\revitmcp_settings.json
{
"server_surface": "mcp",
"external_server_host": "127.0.0.1",
"external_server_port": 8000
}Add RevitMCP to your MCP client configuration
Because the server runs inside Revit on a local port, configure your MCP client to connect to it via HTTP or use the npx wrapper package revitmcp that handles the proxy connection.
{
"mcpServers": {
"revit": {
"command": "npx",
"args": ["-y", "revitmcp"]
}
}
}Verify the connection with a project info query
With Revit open and a project loaded, ask your AI assistant to retrieve the active project metadata. A successful response returns the project name, file path, and Revit version.
Revit Examples
Client configuration
claude_desktop_config.json entry using the revitmcp npm package, which proxies MCP requests to the Revit-hosted server running on localhost:8000.
{
"mcpServers": {
"revit": {
"command": "npx",
"args": ["-y", "revitmcp"]
}
}
}Prompts to try
Example natural language prompts that use RevitMCP's 44 tools to interact with a live Revit model.
- "Get the active project metadata including the file path and Revit version."
- "List all wall elements in the model and their Fire Rating parameter values."
- "Create a door schedule with the Mark, Level, and Width fields."
- "Override the graphic display of selected elements with a red solid fill."
- "Filter all rooms on Level 2 where Area is greater than 200 square feet."Troubleshooting Revit
RevitMCP tab does not appear in the Revit ribbon after cloning
Confirm the cloned folder is named exactly RevitMCP.extension (including the .extension suffix) and is inside the pyRevit Extensions directory. Run pyRevit Reload from the pyRevit ribbon tab and check the pyRevit log for load errors.
MCP client cannot connect — connection refused on port 8000
Make sure you clicked the RevitMCP start button in the Revit ribbon to launch the server process. Check revitmcp_settings.json to confirm the port matches what the client expects, and verify no firewall rule blocks localhost connections.
Tool calls return errors about elements not found
Ensure a Revit project is open and fully loaded before sending requests. Some tools require an active view or selection. Use get_revit_project_info first to confirm the server sees a live document.
