概要

What is MCP 3D Printer Server?

MCP 3D Printer Server is a Model Context Protocol server that enables Claude to interact with 3D printer management systems such as OctoPrint, Klipper (Moonraker), Duet, Repetier, Bambu Labs, Prusa Connect, and Creality/Ender. It provides tools for printer control, file management, STL manipulation, slicing, and monitoring print jobs.

How to use MCP 3D Printer Server?

Install globally via npm with npm install -g mcp-3d-printer-server. Configure a .env file with your printer API key, host, type, and optional settings like temp directory or slicer path. For Claude Desktop, add the server to your mcpServers configuration with the required environment variables, then restart Claude Desktop to connect.

Key features of MCP 3D Printer Server

Get printer status (temperatures, progress, etc.)
List, upload, and manage G-code files
Start, cancel, and monitor print jobs
Manipulate STL files (scale, rotate, translate, modify sections)
Slice STL files to generate G-code
Generate multi-angle SVG visualizations of STL files
Complete end-to-end workflow from STL modification to printing

Use cases of MCP 3D Printer Server

Modify an STL model (e.g., extend base for adhesion) then slice and print it
Check printer temperatures and progress from Claude
Upload and start a print job without manual file handling
Automate STL adjustments (scale, rotate, section modification) before printing
Generate SVG previews of STL files for visual verification

よくある質問

Which printer management systems are supported?

It supports OctoPrint, Klipper (via Moonraker), Duet, Repetier, Bambu Labs, Prusa Connect, and Creality Cloud (Ender series, CR series).

What are the installation prerequisites?

Node.js 18 or higher and npm or yarn are required. Install globally with `npm install -g mcp-3d-printer-server`.

How do I configure a Bambu Labs printer?

Set `PRINTER_TYPE=bambu`, add `BAMBU_SERIAL` and `BAMBU_TOKEN` environment variables. The printer must be on the same network or have cloud connection enabled.

What memory considerations exist for STL tools?

Loading large STL files (>10MB) into memory for manipulation can be memory-intensive. Users should be cautious within MCP environments.

How do I get started with Claude Desktop?

Add the server to your Claude Desktop configuration file under `mcpServers` with the required `env` values (API key, host, printer type). Restart Claude Desktop to begin using the tools.
