Kiln vs gridctl

Kiln: Kiln lets AI agents design, queue, and execute physical manufacturing jobs on real 3D printers with zero human intervention. It exposes printer control through both a CLI and the Model Context Protocol (MCP), making any MCP-compatible agent a first-class operator of your print farm. Supports OctoPrint, Moonraker, Bambu, Prusa Link, and Elegoo printers, plus fulfillment services.; gridctl: Gridctl aggregates tools from multiple MCP servers into a single gateway, allowing you to define your stack in YAML and apply it with one command. It supports various transports (Docker, SSH, stdio, etc.) and provides features like tool filtering, output format conversion, code mode, and skills registry. Designed for fast, ephemeral, and repeatable AI tool environments.
