AI agent control of 3D printers — 737 MCP tools + 202 CLI commands.
Kiln gives AI agents (Claude, GPT, OpenClaw, custom) safe, direct control of 3D printers through the Model Context Protocol. One install and your agent can search model marketplaces, generate designs from text/sketches, slice STL/3MF files, queue prints, monitor progress with camera snapshots, manage multi-printer fleets, and estimate costs — all from a single conversation.
- Bambu Lab — A1, A1 Mini, P1S, P1P, X1C (MQTT + FTP)
- OctoPrint — Any printer running OctoPrint
- Moonraker/Klipper — Voron, Ender, etc.
- Prusa Link — MK4, Mini, XL
- Elegoo — Saturn, Mars, Centauri Carbon (SDCP V2 + V3)
