Public beta. Comfy Cloud MCP is in public beta. APIs, tools, and behavior may change while we iterate. See Feedback to report issues or share suggestions.
Overview
The Comfy Cloud MCP server connects AI agents to Comfy Cloud over the Model Context Protocol. Once connected, you can generate images, video, audio, and 3D, search models, nodes, and templates, and run ComfyUI workflows from a chat with your agent. The server runs remotely atcloud.comfy.org/mcp. Workflows execute on Comfy Cloud GPUs, so you do not need a local GPU. Your agent talks to the server over HTTPS; the server translates tool calls into authenticated requests to Comfy Cloud on your behalf.
Any MCP-compatible client can connect to the same server URL. Claude Code, Claude Desktop, Cursor, and Codex have first-class setup below. Windsurf, Amp, and other agents use the same URL with OAuth or an API key.
Install Comfy Cloud MCP
You need a Comfy Cloud account before connecting. Sign up if you do not have one yet. OAuth sign-in during setup uses your Comfy account.

Install the comfy-cloud plugin. It adds the MCP connection and slash commands in one step. The plugin is published through the Comfy Skills repository, which hosts Claude Code plugins and community agent skills for Comfy.
The plugin adds these slash commands:
| Command | What it does |
|---|---|
/comfy-cloud:generate-image | Generate, edit, or modify an image |
/comfy-cloud:generate-video | Generate, edit, or extend a video |
/comfy-cloud:generate-audio | Generate audio, music, or sound effects |
/comfy-cloud:generate-3d | Generate a 3D model from text or an image |
/comfy-cloud:remove-background | Remove the background from an image |
/comfy-cloud:upscale-image | Upscale an image to higher resolution |
/comfy-cloud:search-templates | Find pre-built workflow templates on comfy.org |
/comfy-cloud:search-models | Search for available models |
/comfy-cloud:search-nodes | Search for nodes and get wiring suggestions |
/comfy-cloud:help | See what you can do with ComfyUI Cloud |

Add the server directly:Then run
/mcp, select comfy-cloud → Authenticate. Add -s user to make it available in all your projects.This path still exposes the same workflows as MCP prompts: /mcp__comfy-cloud__generate-image, /mcp__comfy-cloud__search-models, and so on (the /mcp__<name>__ prefix uses the name you passed to claude mcp add). The plugin above is recommended because it wraps these as the friendlier /comfy-cloud:* commands.
