ComfyUI MCP + Claude diagnosis cuts video gen workflow from 22 to 9 minutes
CanadianDocWild · reddit · 2026-09-16
A ComfyUI user describes using the ComfyUI MCP server with Claude to debug why model loading into VRAM took 8 minutes before generation even started.
With Claude guiding the monitoring process step by step, they discovered the model files were being read from a slow USB 3.0 drive instead of the NVMe SSD — Claude even inferred the drive type from measured transfer speeds. Moving the files back cut a 10-second video generation workflow with upscaling and interpolation from 22 minutes to just over 9. The takeaway: MCP-connected Claude works well for local performance diagnosis, and misplaced model files are an easy mistake to miss.
