概要

What is Comfy MCP Server?

Comfy MCP Server uses the FastMCP framework to generate images based on prompts via a remote Comfy server. It submits prompts to a Comfy server and retrieves generated images.

How to use Comfy MCP Server?

Set the required environment variables (COMFY_URL, COMFY_WORKFLOW_JSON_FILE, PROMPT_NODE_ID, OUTPUT_NODE_ID, OUTPUT_MODE) and optionally OLLAMA_API_BASE and PROMPT_LLM. Launch the server with uvx comfy-mcp-server. Configure it in Claude Desktop by adding the command and environment variables to the MCP server configuration.

Key features of Comfy MCP Server

Use cases of Comfy MCP Server

よくある質問

What does the server do?

It generates images by sending prompts to a remote Comfy server and retrieving the results.

What prerequisites are needed?

You need `uv` (Python package manager), a Comfy server URL, and an exported workflow JSON file from ComfyUI.

How do I configure the environment variables?

Set `COMFY_URL`, `COMFY_WORKFLOW_JSON_FILE`, `PROMPT_NODE_ID`, `OUTPUT_NODE_ID`, and `OUTPUT_MODE`. Optionally set `OLLAMA_API_BASE` and `PROMPT_LLM` for prompt generation via Ollama.

Is Ollama required?

No, Ollama is optional. The server can generate images without it, but if Ollama is available it can be used to turn a topic into a detailed prompt.

What output formats are supported?

The server supports two modes via `OUTPUT_MODE`: `url` to return an image URL, or `file` to return the image as a file.
