Mô tả gốc (cho agent)

Generate images, video, audio, and 3D with Comfy Cloud — search hundreds of models and workflow templates, run custom ComfyUI workflows, and manage generation jobs through the hosted Comfy Cloud MCP server. Cloud-only — connects to the hosted service, not a local ComfyUI install. Use for any "generate/edit an image", "make a video", "text to 3D", or ComfyUI workflow task.

Skill này làm gì

  • Cần chuẩn bị: tài khoản Comfy Cloud (đăng nhập OAuth qua trình duyệt, hoặc API key bắt đầu bằng comfyui-) và kết nối MCP (kênh nối tới dịch vụ) tới cloud.comfy.org/mcp. Không dùng được với ComfyUI cài trên máy.
  • Bạn cần đưa: mô tả ảnh, video, âm thanh hoặc mô hình 3D muốn tạo, hoặc ảnh có sẵn cần chỉnh sửa; có thể chỉ rõ model như Ideogram, Flux, Kling, Veo.
  • Cách hoạt động: với model có tên, gọi thẳng model đối tác; với quy trình phức tạp thì tìm template workflow ComfyUI, chạy hoặc gửi workflow tùy chỉnh, đợi job xong rồi lấy kết quả.
  • Lưu ý: tìm kiếm miễn phí với mọi tài khoản, còn tạo nội dung tốn credit Comfy Cloud và cần gói đăng ký hoặc số dư credit. Link kết quả là link ký tên có hạn, cần tải về nguyên vẹn.

Comfy Cloud

Comfy Cloud runs ComfyUI in the cloud and exposes it to agents as an MCP server: image/video/audio/3D generation via partner models (Ideogram, Flux, Kling, Veo, Seedance, and more) and open-source pipelines, plus full ComfyUI workflow authoring — search templates, override inputs, submit custom graphs, and fetch outputs as signed URLs.

Scope: this skill connects to the hosted Comfy Cloud MCP server and requires a Comfy account — it does not drive a local ComfyUI install. A local-ComfyUI MCP is on the roadmap and will ship as a separate skill; until then, for local instances see comfy-cli.

Connect

The server supports two auth methods: OAuth (browser sign-in, nothing to manage — recommended) and API keys (for headless or CI setups).

Option A — OAuth (recommended)

bash
openclaw mcp set comfy '{"url":"https://cloud.comfy.org/mcp","transport":"streamable-http","auth":"oauth"}'
openclaw mcp login comfy
openclaw gateway restart

openclaw mcp login prints an authorization URL — open it, sign in to your Comfy account, and finish the flow as the CLI directs (it may ask you to rerun with --code <code>). Verify with openclaw mcp status --verbose. Note that OpenClaw ignores static headers on a server entry once auth: "oauth" is set, so don't combine the two.

Option B — API key (headless / CI)

  1. Get an API key — sign in at cloud.comfy.org, then create a key under Settings → API Keys. Keys start with comfyui-.

  2. Export it (put this in your shell profile or OpenClaw's env):

    bash
    export COMFY_API_KEY="comfyui-..."

  3. Register the MCP server with OpenClaw:

    bash
    openclaw mcp set comfy '{"url":"https://cloud.comfy.org/mcp","transport":"streamable-http","headers":{"Authorization":"Bearer ${COMFY_API_KEY}"}}'
openclaw gateway restart

    The server also accepts the key as an X-API-Key: ${COMFY_API_KEY} header, but prefer the Authorization: Bearer form above — standard headers survive every client's proxy layer, and some OpenClaw builds have dropped custom headers on streamable-http transports (see openclaw#65590). If you get a 401 with a key you know is valid, you are probably hitting that: switch to the Bearer form, route through mcporter, or just use OAuth (Option A).

Either way: browsing/search tools work with any account; generation consumes Comfy Cloud credits and needs a subscription or credit balance.

Which tools to use

Images and video from a named model (Ideogram, Flux, Gemini, Kling, Veo, Seedance, …): before calling partner_generate, check whether the named family also has an OSS route — some families (MiniMax H3 is a current example, as of 2026-08) ship BOTH a paid partner node and open-source weights under the identical display title. Run search_templates for the family name alongside search_nodes; if both exist, tell the user the OSS option exists (it has no partner/API fee, but running it still spends ordinary Comfy Cloud compute credits — it isn't free on Comfy Cloud, only free of the partner surcharge) and ask which they want. If only the partner route exists, or the user picks paid, call partner_generate — it runs the provider through Comfy Cloud and saves the result to your asset library. Do not hand-build a workflow for plain text-to-image/video when a partner model is named.

Anything workflow-shaped (open-source models, LoRA/ControlNet, multi-step pipelines): start from a template — search_templates → get_template_schema → run_template with input_overrides. For fully custom graphs use submit_workflow (the graph must end in an output node like SaveImage, or validation rejects it). Save and reuse with save_workflow / run_saved_workflow.

Editing an existing image: upload_file first, then reference the uploaded file from a LoadImage node (or pass it to partner_generate for image-to-image partners). Never inline base64 image data into a workflow.

Getting results: wait_for_job → get_output. Outputs come back as time-limited signed URLs — download them exactly as returned (don't edit query params, they're part of the signature). get_queue and cancel_job manage in-flight jobs; submit_batch / wait_for_batch fan out variations.

Discovery: search_models (checkpoints/LoRAs on the platform), search_nodes (available ComfyUI nodes with wiring hints), get_prompting_guide (model-specific prompting advice).

Example prompts

  • "Generate an image of a cozy bookstore café on a rainy afternoon with Ideogram and download it to ./bookstore.png"
  • "Take ./product.jpg, remove the background, and upscale the result 2×"
  • "Find a text-to-video template for Kling, run it with the prompt 'a paper boat drifting down a rain gutter, cinematic', and give me the output URL"

Notes

  • Generation spends Comfy Cloud credits; search/discovery tools are free.
