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.
