OpenGalatea MCP Server Connects Claude to Prusa 3D Printers
OpenGalatea is an open-source MCP server that bridges Claude AI with Prusa 3D printers through PrusaLink, creating a natural language interface for printer control. The project is built with Python and FastMCP, is Dockerized, and communicates with printers locally over PrusaLink without cloud dependencies. For remote access, it uses ngrok.
Autonomous Workflow Capabilities
Claude can execute this complete workflow autonomously:
- Search Printables.com for 3D models
- Import STL files directly from URLs or from Google Drive/Dropbox
- Ask questions about part requirements (mechanical stress, outdoor use, visual quality) and recommend slice profiles
- Slice models using PrusaSlicer CLI
- Confirm filament is loaded
- Upload and start prints
- Monitor, pause, or stop prints on demand
Technical Implementation
The server is designed to orchestrate multiple printers and scale production from home setups or 3D printer farms using agentic AI capabilities. The author suggests potential future extensions including connecting robotic arms or creating tools for physical object design improvement through closed feedback loops.
The project is fully open-source under the MIT license and available on GitHub. The developer is seeking feedback from those experimenting with MCP or physical world automation using LLMs.
