Setting Up Comfy's Official Local MCP Server (The Easy Way) (Patreon)

Comfy just released comfy-mcp, their official tool that lets Claude Code see and control your local ComfyUI install directly. It knows your real models, your real custom nodes, and can run workflows for you. No screenshotting your graph or pasting JSON and hoping Claude guesses right.

Best part, you don't need to memorize any commands. You just open Claude Code and ask it to set this up for you. Here's exactly what that looked like for me.

So, what does this mean? What can you do with it?

Right now, if you want help with a ComfyUI workflow, you're stuck describing it in words or taking a screenshot and hoping Claude figures out what's actually going on in your graph. It's guessing, because it can't actually see or touch your ComfyUI.

Comfy MCP changes that. Once it's set up, Claude Code can directly look at the ComfyUI running on your computer. Not a screenshot of it, the actual thing. It can see exactly which nodes you have installed, which models and LoRAs you've got sitting on your drive, and how your workflow is wired together.

That means you can do stuff like this, just by typing it in plain English:

"Run this workflow and show me the result" and it actually executes it and pulls the finished image back into the chat.

"What's wrong with this workflow, it's giving me an error" and Claude can look at your real node setup and your real error, not a guess based on a screenshot.

"Build me a workflow that does X" and Claude can check what nodes you actually have available before wiring anything up, so it's not suggesting a node you don't even have installed.

"What models do I have downloaded for this?" and it can check your actual folder instead of asking you to list them out.

Basically, Claude goes from being someone you describe your setup to, to someone who can actually see it and work in it with you. That's the whole shift here.

Step 1: Point Claude Code at your ComfyUI folder

Open Claude Code in your ComfyUI folder and just tell it you want to set up the local ComfyUI MCP.

There are a few different projects out there with "ComfyUI MCP" in the name, so Claude checked with me on which one I meant. I told it to search for the official release. It found Comfy-Org's official comfy-mcp and confirmed that's the real one before doing anything else. Here is the initial message I sent to Claude Code:

Step 2: Approve the plan

Claude laid out what it was about to do before touching anything and asked for the go-ahead. I said yes and it ran the whole install and setup itself.

Step 3: Launch ComfyUI like normal

Once it finished, all I had to do was start ComfyUI the way I always do (run_nvidia_gpu.bat). Claude Code connects to whatever's already running, it doesn't launch ComfyUI for you.

Step 4: Verify it's connected

In a new Claude Code session, I asked it to check the connection. It confirmed it could see my running ComfyUI.

That's it. Everything else, the actual installs, config files, pointing things at the right folders, Claude handled on its own. You don't need to touch a command line or know what any of it means under the hood.

Why this matters

Claude can now see your actual ComfyUI install directly. Your real custom nodes, your real models. It can run a workflow and hand you back the result without you touching the ComfyUI interface at all.

If you want to do this yourself, open Claude Code in your ComfyUI folder and tell it you want to set up the official local MCP server. It'll ask what it needs and handle the rest.Here's an example of what you can do:
