A cloud service for creating images, videos, audio, and 3D content through ComfyUI, a visual workflow tool. It can search workflow templates, change their inputs, run custom workflows, and retrieve the results.

Use it to search and run templates, build custom ComfyUI workflows, submit generation jobs, and collect outputs from Comfy Cloud after signing in with a Comfy account.

It lets an agent use ComfyUI and supported generation models through a hosted service instead of requiring a local ComfyUI installation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00092	$0.01390
Opus 5	$0.00046	$0.00695
Sonnet 5	$0.00018	$0.00278
Haiku 4.5	$0.00009	$0.00139

Security

Grade A, and why

comfy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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)

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)

Get an API key — sign in at cloud.comfy.org, then create a key under Settings → API Keys. Keys start with comfyui-.
Export it (put this in your shell profile or OpenClaw's env):
```
export COMFY_API_KEY="comfyui-..."
```
Register the MCP server with OpenClaw:
```
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).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

comfy is a skill published in the GitHub repository Comfy-Org/comfy-skills (190 stars, last pushed 3d ago), licensed MIT. It adds 92 tokens to every session and 1,390 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
