### Description (declared)

# Comfy MCP Server

> A server using FastMCP framework to generate images based on prompts via a remote Comfy server.

## Overview

This script sets up a server using the FastMCP framework to generate images based on prompts using a specified workflow. It interacts with a remote Comfy server to submit prompts and retrieve generated images.

## Prerequisites

- [uv](https://docs.astral.sh/uv/) package and project manager for Python.
- Workflow file exported from Comfy UI. This code includes a sample `Flux-Dev-ComfyUI-Workflow.json` which is only used here as reference. You will need to export from your workflow and set the environment variables accordingly.

You can install the required packages for local development:

```bash
uvx mcp[cli]
```

## Configuration

Set the following environment variables:

- `COMFY_URL` to point to your Comfy server URL.
- `COMFY_WORKFLOW_JSON_FILE` to point to the absolute path of the API export json file for the comfyui workflow.
- `PROMPT_NODE_ID` to the id of the text prompt node.
- `OUTPUT_NODE_ID` to the id of the output node with the final image.
- `OUTPUT_MODE` to either `url` or `file` to select desired output.

Optionally, if you have an [Ollama](https://ollama.com) server running, you can connect to it for prompt generation.

- `OLLAMA_API_BASE` to the url where ollama is running.
- `PROMPT_LLM` to the name of the model hosted on ollama for prompt generation.

Example:

```bash
export COMFY_URL=http://your-comfy-server-url:port
export COMFY_WORKFLOW_JSON_FILE=/path/to/the/comfyui_workflow_export.json
export PROMPT_NODE_ID=6 # use the correct node id here
export OUTPUT_NODE_ID=9 # use the correct node id here
export OUTPUT_MODE=file
```

## Usage

Comfy MCP Server can be launched by the following command:

```bash
uvx comfy-mcp-server
```
