How do I install Civitai?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Civitai with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Works with setup

Located SKILL.md at plugin/skills/civitai/SKILL.md via the GitHub tree and fetched it raw. Frontmatter parses with name + description (307-char, concrete). Verified the three sibling skills it cites (model-registry, model-compatibility, prompt-engineering) all return HTTP 200, and confirmed the tools it drives are real by grepping src/services/civitai-resolver.ts, which exports searchCivitaiModels/resolveCivitaiModelVersion and comments referencing download_civitai_model. No security smells (no curl|sh, no base64, no exfil); the optional `claude mcp add` line is a legitimate community-server step. Output stage not run: the skill is a driver for the comfyui-mcp MCP server against a ComfyUI backend, which I cannot stand up here, so no baseline-vs-skill artifact exists.

What Civitai does

Guides Claude through the comfyui-mcp built-in tools to search Civitai for checkpoints/LoRAs/embeddings, download them into the right ComfyUI subfolder, and wire them into a workflow with their trigger words. Triggers when a user wants to find, install, or download a Civitai model locally, or pastes a Civitai model URL. Requires the comfyui-mcp MCP server running against a ComfyUI backend.

How to install Civitai

git clone --depth 1 https://github.com/artokun/comfyui-mcp.git /tmp/civitai-src
mkdir -p ~/.claude/skills
cp -R /tmp/civitai-src/plugin/skills/civitai ~/.claude/skills/civitai
# REQUIRES the comfyui-mcp MCP server running against a live ComfyUI backend —
# the skill calls its built-in tools (search_civitai_models, download_civitai_model,
# list_local_models, panel_add_node, generate_image). Without that server the skill
# has no tools to drive. Set up comfyui-mcp per the repo README first.
# Optional: export CIVITAI_API_TOKEN=... (civitai.com/user/account) for gated downloads.
# Optional community MCP: claude mcp add --transport http civitai https://mcp.civitai.com/mcp --header "Authorization: Bearer YOUR_CIVITAI_API_KEY"
# Sibling skills referenced by the body live alongside it: cp -R /tmp/civitai-src/plugin/skills/{model-registry,model-compatibility,prompt-engineering} ~/.claude/skills/

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
