OctoEverywhere's MCP for 3D Printing is a free, private, and secure cloud MCP server that enables AI chatbots, agents, and automation to access your 3D printer remotely. By linking your printer and obtaining an MCP access token, you can query live printer state, monitor progress, and issue commands from any AI workflow. The server provides real-time status and print information, including printer state, progress, elapsed time, estimated time to completion, temperatures for hotend, bed, and chamber, and detailed file and layer data; Gadget AI can detect print failures. It also streams live webcam snapshots with support for multi-camera setups. You can pause, resume, or cancel prints through the MCP interface. The service supports a wide range of printers—OctoPrint, Klipper, Bambu Lab, Creality, Prusa, AnyCubic, Elegoo, and more. It’s accessible from anywhere with easy, no-local-setup configuration and secure, private remote access. Best of all, it’s free for the maker community.
