Civitai Tools (3)
search_models
Search Civitai's catalog of community AI image-generation models (Stable Diffusion checkpoints, LoRAs, textual-inversion embeddings, ControlNets) by text query and/or type. Returns download stats, base model (SDXL / Pony / Flux / SD 1.5), creator and trained trigger words. Defaults to Safe-For-Work…
get_model
Get full details for a single Civitai model by id — description, type, creator, tags, download/rating stats, and every version with its base model, trigger words and downloadable files. Try id 4201 ("Realistic Vision V6.0 B1", a SFW checkpoint). Defaults Safe-For-Work; nsfw flag is surfaced. Keyles…
list_by_type
Browse the top community models of a given type on Civitai (most-downloaded first), optionally filtered to a specific base model. Great for "best SDXL checkpoints" or "top Flux LoRAs". Defaults to Safe-For-Work (mature excluded). Keyless.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Json is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Civitai belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Json when you need capabilities focused on developer tools and Civitai when you require tools for developer tools.
