What is MCP 3D Printer Server?
The MCP 3D Printer Server is a server that enables Claude to interact with various 3D printer management systems through their APIs. It supports systems like OctoPrint, Klipper (via Moonraker), Duet, Repetier, Bambu Labs, Prusa Connect and Creality Cloud, allowing for remote control and monitoring of 3D printers.
How to use MCP 3D Printer Server?
To use the server, you need to install it via npm or from source, configure it with the necessary API keys and printer settings in a .env file, and then configure Claude Desktop to use the server. Specific instructions are provided for each supported printer management system, including Bambu Labs which requires a serial number and access token.
