Comfyui Mcp
A bridge between Claude and your ComfyUI installation that exposes 80+ tools for building and executing image generation workflows. You can queue workflows, manage models and LoRAs, control VRAM, search custom nodes, and retrieve generated assets with full provenance. Ships with slash commands for quick tasks like `/comfy:gen` for text-to-image or `/comfy:debug` to trace failures. Includes autonomous agents that research custom node packs or optimize workflow performance. Works with local installs on any OS, remote instances, and Comfy Cloud. The progress monitor connects to ComfyUI's WebSocket for real-time step updates instead of polling. Useful when you want programmatic control over ComfyUI pipelines without leaving your editor or chat interface.
