Easy AutoCAD MCP server

AutoCAD MCP Server is a powerful integration tool that enables natural language interaction with AutoCAD through large language models like Claude. This server implements the Model Context Protocol (MCP) to create a bridge between AI language models and AutoCAD's drawing capabilities.

Installation Guide

Prerequisites

• Python 3.10 or newer
• AutoCAD 2018+ (with COM interface support)
• Windows operating system

Installation Steps

1. Clone the Repository

git clone https://github.com/yourusername/autocad-mcp-server.git
cd autocad-mcp-server

2. Create a Virtual Environment

For Windows:

python -m venv .venv
.venv\Scripts\activate

For macOS/Linux:

python -m venv .venv
source .venv/bin/activate

3. Install Dependencies

pip install -r requirements.txt

4. Optional: Build as Executable

If you prefer running the server as a standalone executable:

pyinstaller --onefile server.py

Usage Instructions

Running the Server Independently

To start the MCP server:

python server.py

Integrating with Claude Desktop

To use the MCP server with Claude Desktop, you'll need to modify the Claude Desktop configuration file:

1. Locate the configuration file on Windows:

   %APPDATA%\Claude\claude_desktop_config.json
   

2. Add the MCP server configuration:

   {
     "mcpServers": {
       "autocad-mcp-server": {
         "command": "path/to/autocad_mcp_server.exe",
         "args": []
       }
     }
   }
   

Available API Tools

The MCP server provides several functions to interact with AutoCAD:

Drawing Functions

• create_new_drawing: Creates a new drawing file
• draw_line: Draws a straight line between specified points
• draw_circle: Creates a circle with a specified center and radius
• set_layer: Sets the current drawing layer

Analysis and Management Functions

• highlight_text: Highlights text elements matching a specific pattern
• scan_elements: Scans and parses drawing elements
• export_to_database: Exports CAD elements to an SQLite database

Feature Highlights

• Natural language control of AutoCAD drawings
• Basic drawing tools for lines and circles
• Layer management capabilities
• Automatic generation of PMC control diagrams
• Drawing element analysis
• Text pattern matching and highlighting
• Integrated SQLite database for storing CAD elements

The server bridges the gap between AI language models and AutoCAD, allowing for intuitive, conversational control of technical drawing tasks.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "autocad-mcp-server" '{"command":"path/to/autocad_mcp_server.exe","args":[]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "autocad-mcp-server": {
            "command": "path/to/autocad_mcp_server.exe",
            "args": []
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "autocad-mcp-server": {
            "command": "path/to/autocad_mcp_server.exe",
            "args": []
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
