civitai — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited civitai (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Civitai ships an official remote MCP server — discovery and the whole community surface — and comfyui-mcp owns the local machine: download, wire, queue, tag. They compose. comfyui-mcp deliberately does not proxy or re-expose Civitai's tools; MCP clients connect to both servers at once, so the right pattern is pairing, not wrapping.
Look for mcp__civitai__* tools in your session (e.g. mcp__civitai__search_models).
The `comfy` plugin bundles it — its .mcp.json declares the Civitai remote server alongside comfyui, so plugin users get mcp__civitai__* automatically with no manual setup and no key required (the Authorization header defaults to an empty Bearer, which Civitai accepts for its read/browse tools). It just works headless.
plugin, or add the server once:
claude mcp add --transport http civitai https://mcp.civitai.com/mcp \
--header "Authorization: Bearer YOUR_CIVITAI_API_KEY"Until then, fall back to search_models (HuggingFace) + download_civitai_model by id/URL.
API key (optional). Browsing/search needs none. To unlock the user's account context (favorites, posting, gated/early-access downloads), set CIVITAI_API_TOKEN (from civitai.com/user/account) in the environment — the same variable comfyui-mcp uses for its own downloads, so one secret powers both the Civitai MCP header and download_civitai_model.
Civitai's discovery tools return a model id and a model-version id — exactly what comfyui-mcp's download_civitai_model takes. No URL scraping:
mcp__civitai__search_models ──▶ pick a result, read modelVersions[].id

download_civitai_model({ model_version_id, target_subfolder }) # local fetch

list_local_models → panel_add_node loader / generate_image # use ittarget_subfolder must match the model type: checkpoints, loras, vae, controlnet, embeddings, upscale_models, etc. (see the model-registry and model-compatibility skills). Prefer model_version_id — a Civitai page can list several versions and the user usually means a specific one.

download_civitai_model({ model_version_id, target_subfolder: "loras" }).panel_add_node a LoraLoader, panel_set_widget thelora_name, wire it between checkpoint and sampler. Headless: generate_image / build the workflow.
"What's trending on Civitai for product photography?"
mcp__civitai__search_models sorted by trending + search_images forexample outputs and their embedded generation params. Summarize; offer to install any the user likes via the handoff above.
"Download this Civitai page for me" (user pastes a URL)
modelVersionId from the URL if present; otherwisemcp__civitai__get_model to resolve the latest version id, then download_civitai_model. (You can also pass a raw civitai.com/api/download/... URL straight to download_model with CIVITAI_API_TOKEN set.)
The panel's agent is the user's Claude Code session, so if both servers are connected the panel already has every mcp__civitai__* tool next to the panel_* tools — discover on Civitai and wire onto the live graph in one turn, no extra setup. If only comfyui-mcp is connected, suggest adding the Civitai MCP, then proceed with the HF/id fallback.
Civitai's MCP also exposes write/social tools (post, comment, review, direct message, follow, bounties). Those publish on the user's behalf — treat them like any outward-facing action: surface what you're about to post and get an explicit yes first. This skill is about discovery → local install → generation; don't post or message without being asked.
