What is the Comfy Ui MCP server?

Comfy Ui MCP server exists for a simple reason — assistants are far more useful when they can act on Comfy Ui directly instead of describing what you should do. The server implements a simple note storage system with: - Custom note:// URI scheme for accessing individual notes - Each note resource has a name, description and text/plain mimetype.

What the assistant can call

Once Comfy Ui is connected, these are the calls the assistant has available:

  • add-note — Adds a new note to the server
  • Resources — The server implements a simple note storage system with: - Custom note:// URI scheme for accessing individual notes - Each note resource has a name
  • Prompts — The server provides a single prompt: - summarize-notes: Creates summaries of all stored notes - Optional "style" argument to control detail level
  • Tools — The server implements one tool: - add-note: Adds a new note to the server - Takes "name" and "content" as required string arguments - Updates server
  • Debugging — Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the [MCP

Configuration and credentials

You will need one environment variable: UV_PUBLISH_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

@modelcontextprotocol/inspector on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Choosing this one

Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Comfy Ui's toolset — add-note, Resources, Prompts and 2 more — is a fair guide to whether it matches your workflow. It is maintained by jonpojonpo; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the comfy ui mcp server does with a few real requests.

add-noteAdds a new note to the server
ResourcesThe server implements a simple note storage system with: - Custom note:// URI scheme for accessing individual notes - Each note resource has a name, description and text/plain mimetype
PromptsThe server provides a single prompt: - summarize-notes: Creates summaries of all stored notes - Optional "style" argument to control detail level (brief/detailed) - Generates prompt combining all current notes with style
ToolsThe server implements one tool: - add-note: Adds a new note to the server - Takes "name" and "content" as required string arguments - Updates server state and notifies clients of resource changes
DebuggingSince MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector).

Frequently asked questions

It connects Comfy Ui to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (add-note, Resources, Prompts, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Comfy Ui directly.
