bambu-printer-mcp

Overview

This MCP server provides comprehensive control for Bambu Lab 3D printers through the Model Context Protocol. It features STL file manipulation capabilities, direct printer control including pause/resume/skip functions, AMS auto-matching by RFID, camera snapshots, and end-to-end print workflow management. The server supports both pre-sliced 3MF files and optional auto-slicing through BambuStudio CLI integration. Communication occurs via MQTT and FTPS protocols with proper handling of Bambu Lab's specific requirements and quirks.

FAQ

What Bambu Lab printer models are supported?

The server supports A1, A1 mini, P1S, P1P, X1, X1C, X1E, P2S, H2, H2S, H2D, H2C, and H2D Pro models. Camera snapshots work differently across models - TCP on port 6000 for A1/P1S/P1P and RTSP via ffmpeg for X1/P2S/H2 series.

How do I find my printer's serial number and access token?

Open the Bambu Studio app, connect to your printer, go to Settings > Printer > Network. The serial number and access token are displayed there. Alternatively, access the printer's local web interface at http://printer.local and look in the settings section.
