Bambu Printer MCP server

bambu-printer-mcp

Thank you, FULU Foundation, Louis Rossmann, and the OrcaSlicer-bambulab contributors. We stand with open-source developers, the right to repair, and your right to control hardware you own. You should be able to choose your software and print without a vendor cloud standing in the way.

Want to skip Bambu's software and cloud? Use FULU OrcaSlicer-bambulab to slice and export, then this MCP's direct LAN path on supported printers and firmware. That workflow does not require Bambu Studio, Bambu Connect, or Bambu Cloud. Start with the FULU setup guide. The optional BambuNetwork bridge is a separate path that still uses Bambu's networking runtime; cloud jobs still use Bambu's services.

A Bambu Lab-focused MCP server for controlling Bambu printers, manipulating STL files, and managing end-to-end 3MF print workflows from Claude Desktop, Claude Code, or any MCP-compatible client.

Browse the documentation site for searchable setup guides, slicing and AMS guidance, and the full tool reference. It is generated from this README and the docs folder.

Built with help from our contributors. Huge thanks to everyone sharing fixes, careful bug reports, and real printer testing!

This is a stripped-down, Bambu-only fork of mcp-3D-printer-server. All OctoPrint, Klipper, Duet, Repetier, Prusa Connect, and Creality Cloud support has been removed. What remains is a focused, lean implementation for Bambu Lab hardware.

Set up with your agent

Tell your agent your printer's model and LAN address, if you know them, then copy and paste this:

Install bambu-printer-mcp in the agent/harness I'm using now.

Read https://github.com/DMontgomery40/bambu-printer-mcp/blob/main/docs/SETUP.md
and https://github.com/DMontgomery40/bambu-printer-mcp/blob/main/docs/FULU.md
for the current setup instructions and supported workflows.

Detect my OS and harness, then use its native MCP configuration or installer.
Preserve my existing servers and settings. Prefer the published npm package
(npx -y bambu-printer-mcp, stdio); use Node.js 24 if a runtime is needed.

Find existing printer settings in relevant local configuration or available
LAN discovery. Confirm the detected printer's model, address, and identity
with me before connecting. Ask only for values you cannot find:
PRINTER_HOST, BAMBU_MODEL, BAMBU_SERIAL, and BAMBU_TOKEN (the LAN access code).
Keep credentials in local/private configuration; do not repeat access codes
or tokens in chat. Never guess the printer model.

Shortened. The full README is on GitHub.
