name: civitai description: Discover Civitai models with the BUILT-IN download_model action:"search_civitai" and install/generate them locally. Find a checkpoint/LoRA/embedding on Civitai, download it into ComfyUI, and use its trigger words. Optionally pair the official Civitai MCP for community features (images browsing, posting, collections).

Civitai + comfyui-mcp

comfyui-mcp has native Civitai search built in (download_model action:"search_civitai") plus the local half of the loop: download, wire, queue, tag. The full flow (find, install, generate) needs no other server and no API key, and works on every backend, including small local models behind the compact router.

The built-in flow (default path)

download_model({ action: "search_civitai", query, types: ["LORA"], base_models: ["Flux.1 D"] })
        │                    each hit: model_id · model_version_id · trigger words
        ▼
download_model({ action: "download_civitai", model_version_id, target_subfolder: "loras" })
        │
        ▼
list_local_models({ action: "list" })  →  panel_add_node loader / generate_image   # use it

• ALWAYS filter base_models when the user's checkpoint family is known. A Flux LoRA will not load on an SDXL checkpoint (see model-compatibility). CivitAI labels: Flux.1 D, SDXL 1.0, SD 1.5, Pony, Illustrious, Wan Video.
• target_subfolder must match the model type: checkpoints, loras, vae, controlnet, embeddings, upscale_models, and so on.
• Results are SFW-only by default (nsfw: true to opt in).
• Each hit carries trigger words. Put them in the prompt after installing.
• Prefer model_version_id over model_id. A Civitai page can list several versions and the user usually means a specific one.

Search needs no API key. CIVITAI_API_TOKEN (from civitai.com/user/account) unlocks gated/early-access downloads and gated search results. Set it once, in panel Settings under "Set CivitAI token…" or in env.

Recipes

"Find me a good anime LoRA for Flux and install it"

1. download_model({ action: "search_civitai", query: "anime style", types: ["LORA"], base_models: ["Flux.1 D"] }).
2. Present the top 3 to 5 with name, creator, base model, downloads, and the version id. Let the user pick.
3. download_model({ action: "download_civitai", model_version_id, target_subfolder: "loras" }).
4. In the panel, panel_add_node a LoraLoader, panel_set_widget the lora_name, wire it between checkpoint and sampler, and use the hit's trigger words in the prompt. Headless: generate_image(action="image") / build the workflow.

"Download this Civitai page for me" (user pastes a URL)

• Parse the modelVersionId from the URL if present; otherwise pass the model id from the URL to action:"download_civitai" (it resolves the latest version). A raw civitai.com/api/download/... URL also works via action:"download" with CIVITAI_API_TOKEN set.

Optional: the official Civitai MCP (community surface)

For features beyond search and install (browsing example images and their generation params, collections, posting, reviews, bounties), pair the official remote server. It is no longer auto-bundled; add it once:

claude mcp add --transport http civitai https://mcp.civitai.com/mcp \
  --header "Authorization: Bearer YOUR_CIVITAI_API_KEY"

Then mcp__civitai__* tools appear alongside comfyui-mcp's. Its discovery results hand off identically (modelVersions[].id → action:"download_civitai").

That server also exposes write/social tools (post, comment, review, DM, follow). Those publish on the user's behalf, so show what you're about to post and get an explicit yes first. This skill covers discovery, local install, and generation; don't post or message without being asked.
