Easy AutoCAD MCP server

This AutoCAD MCP server enables natural language interaction with AutoCAD through large language models like Claude. It acts as a bridge that translates natural language commands into AutoCAD operations, allowing you to control drawing creation and modification using conversational instructions.

System Requirements

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

Installation

Setting Up the Environment

First, clone the repository and navigate to the project directory:

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

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

Install the required dependencies:

pip install -r requirements.txt

Creating an Executable (Optional)

If you prefer running the server as an executable rather than a Python script:

pyinstaller --onefile server.py

Usage

Running as a Standalone Server

To start the server directly:

python server.py

Integration with Claude Desktop

To use the server with Claude Desktop, you'll need to edit the Claude Desktop configuration file located at:

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

Add the following configuration to the file:

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

Replace "path/to/autocad_mcp_server.exe" with the actual path to your server executable or Python script.

Available Tools

The server provides the following API functions for AutoCAD interaction:

Drawing Creation and Basic Shapes

• create_new_drawing: Create a new AutoCAD drawing
• draw_line: Draw straight lines
• draw_circle: Draw circles

Layer Management

• set_layer: Set the current layer for drawing operations

Analysis and Search

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

Data Integration

• export_to_database: Export CAD element information to SQLite database

Capabilities

The server supports:

• Natural language control for drawing creation and modification
• Basic shapes drawing (lines, circles)
• Layer creation, modification, and deletion
• Automatic generation of professional drawings like PMC control diagrams
• Drawing analysis and element parsing
• Text pattern querying and highlighting
• SQLite database integration for CAD element storage and querying

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.
