Bambu Printer MCP

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. Its 15 documented tools cover stl, printer, filaments, file.

People who work with stl, printer and filaments and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

03 · What Bambu Printer MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can inspect an STL file without modifying it. Returns bounding box dimensions, face count, vertex count, and model center, read the live AMS inventory and resolve each loaded tray to Bambu Studio, and capture a single JPEG frame from the printer's chamber camera. Read-only.

Scale

1 tool - e.g. Scale an STL model along individual axes. Omit any axis to leave it unchanged (defaults to 1.0).

scale_stl

Rotate

1 tool - e.g. Rotate an STL model around one or more axes. Angles are in degrees. Omitted axes default to 0.

rotate_stl

Extend

1 tool - e.g. Add solid geometry underneath the model to increase its base height. Useful for improving bed adhesion on models with a small or unstable footprint.

extend_stl_base

Merge

1 tool - e.g. Merge vertices that are closer together than the specified tolerance. This can close small gaps in a mesh and slightly reduce file size. Useful as a cleanup ste

Center

1 tool - e.g. Translate the model so the center of its bounding box sits at the world origin (0, 0, 0). Useful before applying transformations or exporting for use in another
