Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@comfyops-mcp Generate an image of a cat surfing on a pizza slice"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Wraps ComfyUI so you can generate images, video, and upscales from a prompt — without ever touching the node editor. Pick a curated workflow, type what you want, get a PNG or MP4.

What's ComfyUI? It's the engine room of local AI image generation. You connect boxes labelled "KSampler", "CLIP Text Encode", and "VAE Decode" with wires, like a Moog synthesizer made by someone who hates knobs. It's incredibly powerful and completely impenetrable.
What's this? comfyops-mcp is a butler for ComfyUI. You tell it what you want — "a cat surfing on a pizza slice" — and it picks the right boxes, wires them up, and hands you the result. No node editor, no patch cables, no "what's a CFG scale?"
What can it do?
Turn text into images — verified: FLUX.2 klein 4B (seed-reproducible) and SD 1.5; curated: SDXL, FLUX.1 family, Z-Image, PixArt, Lumina2
Turn text or photos into short videos — curated (Wan 2.1/2.2, Hunyuan, LTX, Mochi, Cosmos) — not yet end-to-end verified
Upscale / restore old images — curated (ESRGAN, SUPIR) — not yet end-to-end verified
Inpaint and edit (SD1.5 inpaint/img2img; FLUX fill curated)
Browse and catalog workflows from the community
Remember every generation with its seed so you can reproduce it later
Who is it for?
You, who just wants pictures — prompt in, PNG out
You, who has an RTX 4090 gathering dust — put it to work
You, who already uses ComfyUI — now your AI assistant can drive it
You, who saw a cool AI image online and wants to make one
If you already know ComfyUI: comfyops registers curated workflows from
workflows/as MCP tools. You can add your own withcomfy_workflows/register. The workflows dir is yours — export from the node editor, drop in, done.
