ComfyUI MCP Server is designed to integrate ComfyUI with the Model Context Protocol, allowing for enhanced server functionality using built-in and custom workflows. It is a tool for managing and deploying workflows that convert text to images and more, deployed via UV or Docker.

ComfyUI MCP Server

  • A server implementation for integrating ComfyUI with Model Context Protocol (MCP).
  • Requires a running ComfyUI server; you need to host it or have access to one.

  • text_to_image: Returns the URL of the generated image. Use download_image to get the actual image.
  • download_image: Downloads images generated by other tools.
  • run_workflow_with_file: Run a workflow by providing the path to a workflow JSON file.
  • run_workflow_with_json: Run a workflow by providing the workflow JSON data directly.

Installation and Configuration

  • Set ComfyUI host and port in src/.env.
  • Add custom workflows by placing JSON files in the workflows directory.

Running the Server

  • Recommended to use UV for running the server.
  • Use Docker for containerized deployments; special considerations needed for image data and URLs.

Debugging
