Architecture Overview

src/comfyui_mcp/

• __about__.py: Version and license metadata
• argument_parser.py: CLI argument definitions using pydantic
• base_types.py: Shared type aliases
• function_utils.py: Dynamic function wrapper generation
• workflow_loader.py: Load workflows from disk or ComfyUI API
• workflow_utils.py: Workflow preparation and invocation
• server.py: FastMCP server entry point

How It Works

1. Workflow discovery: fetch remote or local JSON.
2. Tool generation: parameters mapped into callable MCP tools.
3. Execution: runs workflow via ComfyUI API and returns image URLs as Markdown.
4. Batching: repeated invocations, seed randomization.
