mcp-3D-printer-server MCP server

Connects MCP to major 3D printer APIs (Orca, FULU's Orca/Bambu, OctoPrint, Klipper, Duet, Repetier, Prusa, Creality). Control prints, monitor status, and perform advanced STL operations like scaling, rotation, sectional editing, and base extension. Includes slicing and visualization.

What mcp-3D-printer-server does

Summarised from the project README; check the repository for the latest details.

Features

• Seven printer backends, selected with `PRINTERTYPE`: OctoPrint, Klipper (Moonraker), Duet, Repetier-Server, Bambu Lab, PrusaLink or Prusa Connect, and Creality
• Per-call `type`, `host`, `port`, and `apikey` arguments for working with more than one printer
• Printer status, file listing, G-code upload from inline content or a local path, starting a stored file, cancelling a job, and setting bed or nozzle temperatures
• STL tools: inspect dimensions, scale, rotate, translate, extend the base, merge vertices, center, lay flat, transform one section of a model, and render multi-angle SVG previews
• Slicing through PrusaSlicer, Slic3r, OrcaSlicer, CuraEngine, FULU OrcaSlicer-bambulab, or Bambu Studio command lines, with G-code peak-temperature checks and a one-call process-and-print pipeline
• Bambu-compatible CLI slicing with the exact model and nozzle machine preset resolved from your slicer installation, filament slots and colours, placement options, and a local template registry
