# ComfyUI for Developers: SDKs, Server API, and Cloud

> Build on ComfyUI with official Python and TypeScript SDKs, run it as a server, call Cloud APIs, or connect AI agents via MCP.

ComfyUI is a modular GenAI inference engine that can be run as a server, accessed via API, extended with custom nodes, and managed from the command line. Most API work follows two steps: get ComfyUI running somewhere, then run workflows against it from your application.
