# revit-mcp

English | [简体中文](README_zh.md)

## 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](https://github.com/revit-mcp/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](https://github.com/revit-mcp/revit-mcp-plugin)

## Installation

### 1. Build local MCP service

Install dependencies

```bash
npm install
```

Build

```bash
npm run build
```

### 2. Client configuration

**Claude client**

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

```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.
