MCP 3D Printer Server

Example Use Cases

• 1

  Query printer status, list files, upload G-code, start or cancel jobs across multiple printer management systems (OctoPrint, Klipper, Duet, etc.).

• 2

  Perform in-server STL operations—analyze geometry, scale/rotate/translate, extend bases, merge vertices, lay flat, generate SVG visualizations, and then slice models using installed slicers.

• 3

  Manage Bambu Lab workflows—read Bambu Studio presets, upload .3mf files via FTP, and initiate prints via MQTT with limited parameter overrides.

Description

This project implements an MCP server to connect Claude (and other MCP agents) to 3D printer management systems such as OctoPrint, Klipper (Moonraker), Duet, Repetier, Bambu Labs, Prusa Connect, and Creality Cloud. It provides printer control (status, start/cancel prints, upload files), advanced STL model operations (scale, rotate, extend base, visualizations), and slicing/integration with external slicers. The server includes Bambu-specific features like .3mf parsing, FTP upload, and MQTT-based print commands, and is distributed as an open-source Node.js/TypeScript package with Docker support.
