MCP 服务器

Revit MCP Server

Allows AI assistants to interact with Autodesk Revit through the MCP protocol, enabling the AI to create, modify, and delete elements in Revit projects.

Tools

ai_element_filter

An intelligent Revit element querying tool designed specifically for AI assistants to retrieve detailed element information from Revit projects. This tool allows the AI to request elements matching specific criteria (such as category, type, visibility, or spatial location) and then perform further analysis on the returned data to answer complex user queries about Revit model elements. Example: When a user asks 'Find all walls taller than 5m in the project', the AI would: 1) Call this tool with parameters: {"filterCategory": "OST_Walls", "includeInstances": true}, 2) Receive detailed information about all wall instances in the project, 3) Process the returned data to filter walls with height > 5000mm, 4) Present the filtered results to the user with relevant details.

color_elements

Color elements in the current view based on a category and parameter value. Each unique parameter value gets assigned a distinct color.

send_code_to_revit

Send C# code to Revit for execution. The code will be inserted into a template with access to the Revit Document and parameters. Your code should be written to work within the Execute method of the template.

create_line_based_element

Create one or more line-based elements in Revit such as walls, beams, or pipes. Supports batch creation with detailed parameters including family type ID, start and end points, thickness, height, and level information. All units are in millimeters (mm).

create_point_based_element

Create one or more point-based elements in Revit such as doors, windows, or furniture. Supports batch creation with detailed parameters including family type ID, position, dimensions, and level information. All units are in millimeters (mm).

create_surface_based_element

Create one or more surface-based elements in Revit such as floors, ceilings, or roofs. Supports batch creation with detailed parameters including family type ID, boundary lines, thickness, and level information. All units are in millimeters (mm).

delete_element

Delete one or more elements from the Revit model by their element IDs.

get_available_family_types

Get available family types in the current Revit project. You can filter by category and family name, and limit the number of returned types.

operate_element

Operate on Revit elements by performing actions such as select, selectionBox, setColor, setTransparency, delete, hide, etc.

get_current_document_info

获取 Revit 当前活动视图的详细信息，包括视图类型、名称、比例等属性。

get_current_view_elements

Get elements from the current active view in Revit. You can filter by model categories (like Walls, Floors) or annotation categories (like Dimensions, Text). Use includeHidden to show/hide invisible elements and limit to control the number of returned elements.

get_current_view_info

获取 Revit 当前活动视图的详细信息，包括视图类型、名称、比例等属性。

get_selected_elements

Get elements currently selected in Revit. You can limit the number of returned elements.

open_document

Open Document

tag_all_walls

Create tags for all walls in the current active view. Tags will be placed at the middle point of each wall.

README

revit-mcp

English | 简体中文

Description

revit-mcp allows you to interact with Revit using the MCP protocol through MCP-supported clients (such as Claude, Cline, etc.).

This project is the server side (providing Tools to AI), and you need to use revit-mcp-plugin (driving Revit) in conjunction.

Features

Allow AI to get data from the Revit project
Allow AI to drive Revit to create, modify, and delete elements
Send AI-generated code to Revit to execute (may not be successful, successful rate is higher in some simple scenarios with clear requirements)

Requirements

nodejs 18+

Complete installation environment still needs to consider the needs of revit-mcp-plugin, please refer to revit-mcp-plugin

Installation

1. Build local MCP service

Install dependencies

npm install

Build

npm run build

2. Client configuration

Claude client

Claude client -> Settings > Developer > Edit Config > claude_desktop_config.json

{
    "mcpServers": {
        "revit-mcp": {
            "command": "node",
            "args": ["<path to the built file>\\build\\index.js"]
        }
    }
}

Restart the Claude client. When you see the hammer icon, it means the connection to the MCP service is normal.
