Usage

• •With ComfyUI running, ask Claude to generate an image — it finds (or downloads) a checkpoint, builds a workflow, executes it, and returns the image.
• •Slash commands: /comfy:gen <prompt>, /comfy:debug [prompt_id], /comfy:batch (parameter sweeps over cfg/steps/sampler/seed/…), /comfy:recipe <name> (portrait, hires-fix, style-transfer, product-shot), /comfy:convert, /comfy:install <pack>, /comfy:gallery, /comfy:compare, /comfy:viz, /comfy:node-skill.
• •Point at any ComfyUI: `npx -y comfyui-mcp@latest --comfyui-url http://192.168.1.50:8188`; remote mode via --force-remote; cloud mode via COMFYUI_API_KEY (Comfy Cloud).
• •Expose as a hosted connector with one command: `npx -y comfyui-mcp@latest --tunnel` (streamable-HTTP + cloudflared tunnel + auth token).

Best for

AI-driven ComfyUI workflow authoring and image/video generation for Claude/ChatGPT/Gemini users — including fully offline use with a free local LLM via Ollama — on your own (local, LAN, VPS, or Comfy Cloud) install.

Caveats

• ⚠Requires Node.js >= 22 and a running ComfyUI (or a remote/cloud target); tool calling is a hard requirement for the model (no tool calling = doesn't work); thinking and vision strongly recommended.
• ⚠Cloud mode (COMFYUI_API_KEY) routes via cloud.comfy.org; WebSocket and local-only tools throw CLOUD_UNSUPPORTED.
• ⚠Optional API tokens: CIVITAI_API_TOKEN, HUGGINGFACE_TOKEN, GITHUB_TOKEN; paid API credits are guarded (check_runtime classifies workflows as local vs api).
• ⚠Library/package is not affiliated with Comfy-Org; Comfy-Org ships its own Comfy Cloud MCP / In-App Agent for zero-setup cloud use.
