# ComfyUI Node Registry

Search and discover from 8400+ ComfyUI nodes.

## MCP Tools

| Tool | Purpose |
|------|---------|
| `comfy_search` | Search nodes by keyword - use this first |
| `comfy_spec` | Get full node spec (inputs, outputs, types) - use after finding a node |
| `comfy_author` | Find nodes by author (kijai, filliptm, Lightricks) |
| `comfy_categories` | Browse all node categories |
| `comfy_packs` | Browse all node packs |
| `comfy_stats` | Registry statistics |

## Search Examples

Search uses smart aliases - "ltx" expands to ltx, ltx2, lightricks, etc.

```
comfy_search("controlnet")      → ControlNet loaders and apply nodes
comfy_search("upscale model")   → Model-based upscalers
comfy_search("audio reactive")  → Audio-driven effect nodes (amplitude, rms, onset...)
comfy_search("ltx sampler")     → LTX video sampling nodes
comfy_search("mask grow")       → Mask expansion/dilation nodes
comfy_search("face")            → Face detection, swap, restore nodes
comfy_search("v2v")             → Video-to-video nodes (vid2vid, video2video...)
```

## Workflow

1. **Search**: `comfy_search("your task")`
2. **Inspect**: `comfy_spec("NodeName")` for promising results
3. **Browse**: Use `comfy_author`, `comfy_categories`, `comfy_packs` to explore
