Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01535 |
| Opus 5.5 | $0.00037 | $0.00614 |
| Sonnet 5.5 | $0.00018 | $0.00307 |
| Haiku 4.5 | $0.00009 | $0.00153 |
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 2d 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 — 122 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 restartThe server also accepts the key as an
X-API-Key: ${COMFY_API_KEY}header, but prefer theAuthorization: Bearerform 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 a401with 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 (236 stars, last pushed yesterday), licensed MIT. It adds 92 tokens to every session and 1,535 once invoked, about $0.0004 per session on Opus 5.5. 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.
