ComfyUI MCP

ComfyUI MCP is an MCP server and Claude Code plugin for ComfyUI. It connects an AI assistant to a running ComfyUI instance so that images, video, and audio can be generated, workflows can be authored and run, and models and custom nodes can be managed in natural language. The documentation describes it as a local-first, agent-native control plane for ComfyUI.

Its listed capabilities include text-to-image generation through generate_image, with ControlNet and IP-Adapter conditioning, as well as workflow creation from templates. Workflows can also be modified, validated, visualized, and round-tripped using a compact DSL. In addition, it can search HuggingFace and CivitAI, download, list, and remove models, and it supports installing, updating, snapshotting, and bisecting node packs via ComfyUI-Manager. It also covers installing and updating ComfyUI itself, inspecting the environment, and starting or stopping the server.

ComfyUI MCP is described as working with local, remote, or Comfy Cloud setups. It can auto-detect a local ComfyUI installation, point to a remote instance with --comfyui-url, or talk to Comfy Cloud through COMFYUI_API_KEY, and it is stated to work on macOS, Linux, and Windows. The documentation also says that the server can be added to Claude Code and that the tool includes 80+ tools documented from their live schemas. Source and issues live on GitHub.
