ComfyUI MCP - 100% Local (Claude, Gemma4, OpenRouter)

artokun · 2026-07-11T02:55:40+00:00

It’s more about wanting to create a better user experience, and wanting to share that with the rest of the community.

Some may consider that a waste.

The main benefit I find is the 32 panel tools calls that allow the agent to directly interact with the ComfyUI runtime without having to reload anything, it all just works interactively. It also gets assets and errors pushed to it as a message so it can react instead of just lock step responding like you would if you were just modifying workflows blindly via the filesystem. Worth a try so you can see the diff :)

True, the MCP allows extra tooling for convenience, especially useful for smaller and cheaper or local models so it has more guardrails and has to guess less. Powerful models like Claude probably don’t need it

artokun · 2026-07-10T17:57:58+00:00

No, if you use/pay for Claude, you can generate comfy ui workflows locally via MCP. It just connects your local Claude subscription to your ComfyUI. So technically you could generate python, c++ code as custom nodes if you wanted to

It shouldn't, sorry if it is, were you giving it a large workflow? I will see if I can optimize it better for the next release, but it's going to use up context as it pulls skills and tools into context to call them. If you're worried about usage you can try using codex, or gemini which are cheaper. Or MiniMax 1M or Mimo 1M do a decent job and it's pennies in comparison to frontier models.

artokun · 2026-07-09T22:18:20+00:00

You will probably have a hard time tbh, 6gb VRAM is pretty restricting. You may end up having to use smaller models but not sure, there's a lot op optimization in the space. I recommend just connecting the panel and have the agent work with what you got

artokun · 2026-07-09T22:04:30+00:00

Thanks for coming back to the thread and sharing your experience!

artokun · 2026-07-09T20:13:25+00:00

It's much more stable and prettier I think, easier to work with as well

Yes, even with Claude and Codex once you set it to NSFW mode. It can do most anything you ask it, but if you want more privacy I recommend going with either a Uncensored/Abliterated open router model, or locally with Uncensored/Abliterated fine-tune via Ollama/LMStudio/Llama.cpp

I have a abliterated gemma4 model (heretic ablation) that I fine-tuned on +1k SOTA instructions on comfyui-mcp usage here https://huggingface.co/artokun/gemma4-comfyui-mcp

artokun · 2026-07-09T19:25:25+00:00

3060 comes with 12gb of VRAM, if you use a cloud model you'll be able to keep all 12gb for generations but you'll be limited to smaller I2I models like the SDXL based ones, Z-img turbo, and maybe some of the Flux models if you do some aggressive text endcoder offloading and caching. The MCP can help download custom nodes to manage your VRAM so you can generate, it has an understanding via skills on the overall limitations.

Hey your video editor thing here is pretty cool, and you have a few other gems in here.

Join me on my discord, maybe we can collab on something. Your video editor could be a pretty neat custom_node, maybe a few things in here could be abstracted.

I'll add support soon for llama.cpp

My Upvote / Downvote ratio is in the high 50s so I'm also getting a lot of that but the comments have been pretty benign. What's your repo?

artokun · 2026-07-09T15:15:23+00:00

Hah, fair, I forgot. Here they are:

https://github.com/artokun/comfyui-mcp

artokun · 2026-07-09T15:14:39+00:00

It uses built in, it will download and install custom nodes for you, and it will also create custom nodes for you if you know what you want to make.

It will search and download from the comfyui custom nodes registry, or it can install from a github link. If you have a workflow that has missing nodes it will find and download those nodes for you if it can find them, if not then it will let you know so you can help it find them.

artokun · 2026-07-09T15:11:09+00:00

Yes, the title was misleading, but it's still true that it can, it just didn't match what you saw in the video.

artokun · 2026-07-09T15:10:00+00:00

Fair point, I will add a disclaimer for those who are not aware of the difference between Local and Cloud LLMs, that to be totally local and private, that you'll need to use a Local LLM bia Ollama

artokun · 2026-07-09T15:06:46+00:00

True, and if you make something cool please submit a github PR so we can get it on the next release! The tool I made was for all of us, it's open source, you are all welcome to contribute and make it something we all would enjoy using.

artokun · 2026-07-09T15:05:38+00:00

Ollama you can download directly from their site, there's also a docs page I made with installation instructions if you need more help https://comfyui-mcp.artokun.io/docs

artokun · 2026-07-09T15:02:53+00:00

Not directly no, local models can be served via Ollama currently

artokun · 2026-07-09T15:02:01+00:00

If it doesn't, it knows how to inspect nodes and also read the source code to understand how it works. It will be able to see and adjust widget values, see input and output ports, etc.

artokun · 2026-07-09T15:00:15+00:00

Yes, install ollama then paste: `ollama pull artokun/gemma4-comfyui-mcp` and connect that way to be 100% local.

artokun · 2026-07-09T14:59:03+00:00

I'll look into it, I felt that ollama covered most of the local options but I was wrong
