FastMCP Resources

This server also provides structured resource definitions that can be accessed via FastMCP resource URIs:

Model Resources

• civitai://models/{limit} - List models with filtering options (limit parameter required)

• civitai://models/{model_id} - Get specific model details

Model Version Resources

• civitai://model-versions/{version_id} - Get model version details

• civitai://model-versions/by-hash/{hash} - Get model version by file hash

Image Resources

• civitai://images/{limit} - List images with filtering options (limit parameter required)

Creator Resources

• civitai://creators/{limit} - List creators (limit parameter required)

Tag Resources

• civitai://tags/{limit} - List tags (limit parameter required)

These resources provide structured data models that can be used programmatically by MCP clients.

API Key

A Civitai API key is not required but recommended for:

• Access to private models

• Higher rate limits

• Some advanced features

You can get an API key from your Civitai account settings.

Examples

# Search models
search_models(query="anime", limit=10, sort="Most Downloaded")

# Get specific model details
get_model(model_id=12345)

# Get popular LORA models
get_models_by_type(type="LORA", sort="Most Downloaded", limit=5)

# Get images
get_images(limit=20, nsfw="None", sort="Newest")

Notes

• API responses can be large

• Use NSFW filtering options appropriately

• Store API keys securely using environment variables
