ComfyUI MCP

An open-source, self-hosted MCP server that wraps ComfyUI to expose image generation capabilities via HTTP/SSE. It allows AI agents like Claude Code or Cursor to request images using SDXL presets without requiring local installation of PyTorch or heavy dependencies on the client side, acting as a middleware that communicates with a backend ComfyUI instance.
