# Kiln

AI agent control of 3D printers — <!-- KILN_MCP_CAPABILITY_COUNT:OLD --> 819 MCP capabilities + <!-- KILN_CLI_COUNT:OLD --> 223 CLI commands.

## What it does

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.

## Supported printers

- **Bambu Lab** — A1, A1 Mini, P1S, P1P, X1C (MQTT + FTP)
- **OctoPrint** — Any printer running OctoPrint
- **Moonraker/Klipper** — Voron, Ender, etc.
- **Creality** — K1/K2/Hi/Ender V3 KE-class printers when local Moonraker is reachable; older Marlin models via OctoPrint or serial
- **Prusa Link** — MK4, Mini, XL
- **Elegoo** — Saturn, Mars, Centauri Carbon (SDCP V2 + V3)

## Install

```bash
pip install kiln3d
```

Or with pipx:
