How to Set Up and Use AutoCAD
The AutoCAD MCP Server enables AI agents to control a live AutoCAD instance on Windows through Python and the AutoCAD COM API, enabling natural-language drawing of geometric shapes like lines, circles, rectangles, polylines, and text. It exposes 14 tools for drawing, layer management, entity editing (move, rotate, copy), and database querying, making it possible for Claude or other LLMs to act as a CAD co-pilot. Developers and engineers use it to automate repetitive drafting tasks, generate geometry from specifications, or explore drawings through conversational queries.
Prerequisites
- Windows OS (COM interface requirement)
- AutoCAD 2018 or later installed with COM interface support enabled
- Python 3.10 or later installed
- An MCP-compatible client such as Claude Desktop
Clone the repository
Clone the Easy-MCP-AutoCad repository to your local machine on Windows.
git clone https://github.com/zh19980811/Easy-MCP-AutoCad.git
cd Easy-MCP-AutoCadCreate a virtual environment and install dependencies
Create a Python virtual environment and install the required packages including pywin32 for COM automation.
python -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txtOpen AutoCAD
Launch AutoCAD and open or create a drawing. The MCP server connects to the running AutoCAD process via the COM interface — AutoCAD must be open before the server starts.
Start the MCP server
Run the server script from within the virtual environment. It will connect to the running AutoCAD instance via COM and begin listening for MCP tool calls.
.venv\Scripts\activate
python server.pyConfigure Claude Desktop
Add the AutoCAD MCP server to your Claude Desktop configuration file. Use the full path to the virtual environment's Python interpreter and the server script, using forward slashes or double backslashes.

}Prompts to try
Example prompts that use the AutoCAD MCP server's drawing and editing tools.
- "Draw a rectangle with corners at (0,0) and (100,50) on the current layer"
- "Create a new layer called 'Dimensions' and make it blue"
- "Draw a circle at the center point (50,50) with a radius of 25"
- "Add the text 'Floor Plan Level 1' at position (10, 120) with a height of 5"
- "Move the last entity I drew 10 units to the right"
- "Scan all entities in the drawing and count how many are lines vs circles"Troubleshooting AutoCAD
Server fails to connect to AutoCAD with a COM error on startup
Make sure AutoCAD is already running and has a drawing open before starting server.py. The server connects to an already-running AutoCAD instance via COM — it cannot launch AutoCAD itself. Also verify pywin32 installed correctly with '.venv\Scripts\python -c "import win32com.client"'.
Claude Desktop cannot find the Python interpreter or server.py
Use absolute paths with forward slashes (C:/path/to/file.py) or double backslashes (C:\\path\\to\\file.py) in claude_desktop_config.json. Windows path separators in JSON must be escaped or converted to forward slashes.
Drawing commands succeed but nothing appears in AutoCAD
Run the 'REGEN' command in AutoCAD to force a display refresh, or use the zoom/extents command to navigate to where the new geometry was created. The COM API may draw entities outside the current viewport.
