xml.Revit.MCP Tools Overview

English | 中文文档

xml.Revit.MCP provides a comprehensive set of tools for integrating with Autodesk Revit through the Model Context Protocol (MCP). This library serves as a bridge between AI assistants and Revit, enabling powerful automation capabilities and programmatic interaction with building models.

Key Features

The tool library includes numerous functions for Revit automation and interaction:

Basic Operations:

• Get available commands from Revit plugin
• Execute specified commands in Revit
• Call specific Revit functions with parameters
• Retrieve view data and selected elements

Element Management:

• Find elements by category
• Get element parameters and locations
• Update element parameters
• Delete elements
• Show/highlight elements in current view
• Move elements to new positions

Creation Tools:

• Create levels/floors
• Create floor plan views
• Create grid lines
• Create walls and floors
• Create rooms and room tags
• Create doors and windows
• Create MEP elements (ducts, pipes, cable trays)
• Create family instances
• Link DWG files
• Create sheets

Installation Requirements

• xml.Revit: Version 1.3.4.3 or newer
• Python: 3.10 or newer
• UV Package Manager: Required for installation
• Revit: Compatible with versions 2019-2024 (with plugin)

Installation Process

1. First, install the UV package manager:

   pip install uv

2. Install the revit-mcp package:

   pip install revit-mcp

3. Test the installation:

   uvx revit-mcp

   You should see: RevitMCPServer - INFO - Successfully connected to Revit on startup

Extending Functionality

You can create custom MCP DLL files to implement additional functionality by:

1. Implementing the xml.Revit.MCP.Public.IMCPMethod interface
2. Following JSON-RPC 2.0 specification for communication
3. Compiling to a DLL and placing it in the designated MCP folder

Plugin Configuration

When using the revit-mcp-plugin:

1. Register the plugin with Revit
2. Configure commands through: Add-in Modules → Revit MCP Plugin → Settings
3. Enable the service: Add-in → Revit MCP Plugin → Revit MCP Switch

Once enabled, AI assistants can discover and control your Revit program, executing the various commands provided by the xml.Revit.MCP tools library.
