Easy AutoCAD MCP server

This MCP server integrates AutoCAD with large language models like Claude, enabling natural language interaction with AutoCAD. It allows you to control drawing creation and modification through conversational commands rather than traditional CAD inputs.

Installation

Prerequisites

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

Setup Steps

1. Clone the repository:

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

2. Create and activate 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 an executable:

pyinstaller --onefile server.py

Usage

Running as a Standalone Server

Simply start the server with:

python server.py

Integration with Claude Desktop

To integrate with Claude Desktop, edit the Claude Desktop configuration file:

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

Add the following configuration:

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

Available Tools

The MCP server provides the following functions for AutoCAD interaction:

Drawing Creation and Manipulation

• create_new_drawing: Create a new AutoCAD drawing
• draw_line: Draw a line
• draw_circle: Draw a circle

Layer Management

• set_layer: Set the current layer

Analysis and Highlighting

• highlight_text: Highlight matching text patterns
• scan_elements: Scan and parse drawing elements

Data Integration

• export_to_database: Export CAD element information to SQLite database

Supported Features

• Natural language control of AutoCAD
• Basic drawing (lines, circles, etc.)
• Layer creation, modification, and deletion
• Automatic generation of specialized drawings (e.g., PMC control diagrams)
• Drawing analysis and element scanning
• Text pattern querying and highlighting
• Database integration with SQLite

How to add this MCP server to 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 > MCP and click "Add new global MCP server".

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

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
