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.

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 | $0.00091 | $0.02099 |
| Opus 5 | $0.00046 | $0.01050 |
| Sonnet 5 | $0.00018 | $0.00420 |
| Haiku 4.5 | $0.00009 | $0.00210 |
Grade A, and why
model-registry 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 4d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Model Registry
One table per family: filename → source URL → target subdir under
<COMFYUI>/models/. Use with download_model(url, target_subfolder, filename).
This registry grows with every release — if a model you need is missing, use
search_models (HuggingFace) or download_civitai_model and consider
contributing the row.
Conventions
- HF "resolve" URLs download directly:
https://huggingface.co/<repo>/resolve/main/<path> - 🔒 = gated repo — needs
HUGGINGFACE_TOKEN(accept the license on the HF page first) - CivitAI model-page URLs need
download_civitai_model(resolves version → file); rawcivitai.com/api/download/...URLs work withdownload_model+CIVITAI_API_TOKEN - Always verify the exact filename a workflow's loader expects —

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.
- 4d ago First seen · 102 lines · 91 tokens per session scan A d19386a76ef0
model-registry is a skill published in the GitHub repository sandyup/comfyui-mcp (1 stars, last pushed 1mo ago), licensed MIT. It adds 91 tokens to every session and 2,099 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 2026-08-31.
