Kiln vs fast-agent
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.; fast-agent: fast-agent is a CLI-first framework for building and interacting with sophisticated multimodal AI agents and workflows. It offers comprehensive support for various LLM providers, structured outputs, and vision, with unique features like MCP Feature support and live streaming responses to the terminal.
