Comfy Cloud MCP

Connect your AI agent to Comfy Cloud for image generation, model search, and workflow management — directly from Claude, Cursor, and other MCP-compatible clients.

Note

Research Preview — This MCP server is currently in limited early access. Interested? Sign up for the waitlist.

Install

macOS / Linux:

curl -fsSL https://raw.githubusercontent.com/Comfy-Org/comfy-cloud-mcp/main/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/Comfy-Org/comfy-cloud-mcp/main/install.ps1 | iex

The installer will:

1. Detect your MCP clients (Claude Code, Cursor, Amp)
2. Ask for your Comfy Cloud API key
3. Configure the remote MCP server
4. Optionally install slash commands for better workflow context

No Node.js or other dependencies required.

Claude Desktop (chat mode): Requires OAuth, which is coming soon. In the meantime, use Code mode within the Claude Desktop app — it connects to Comfy Cloud automatically via the Claude Code config.

What you can do

Once installed, your AI agent can:

• Generate images — describe what you want, the agent builds and runs a ComfyUI workflow
• Search models — find checkpoints, LoRAs, VAEs, and controlnets across HuggingFace and CivitAI
• Search nodes — discover ComfyUI nodes by category, input/output type, or keyword
• Browse templates — find pre-built workflows for text-to-image, image-to-video, style transfer, and more
• Manage workflows — list, inspect, and run your saved workflows from Comfy Cloud
• Chain outputs — use the output of one workflow as input to another

Slash commands

The MCP tools work automatically — just ask your agent to generate an image or search for models. These optional slash commands provide shortcuts with extra context for Claude Code:

Command	Description
/comfy-generate-image	Generate images from a text description
/comfy-search-models	Search available models with formatted results
/comfy-search-nodes	Search for nodes and get wiring suggestions
/comfy-search-templates	Find pre-built workflow templates
/comfy-help	See what you can do with ComfyUI Cloud
