Open-source ComfyUI MCP toolkit lets Claude Code drive video models on an 8GB laptop GPU
KeyAdventurous3113 · reddit · 2026-09-04
A developer packaged an open-source (MIT) setup that lets MCP-capable agents like Claude Code and Cursor drive a local ComfyUI, running heavy video models (MiniMax H3, Wan 2.1, LTX-Video) on an 8GB laptop GPU with no cloud account or per-generation billing.
What's inside:
- A paste-ready MCP config running local ComfyUI
- A comfylocal pure-REST fallback skill: zero-dependency Python client that keeps working when the MCP server is offline
- Hard-won 8GB field notes: GGUF/fp8 only; resolution is the real VRAM lever (0.9MP OOMs where 0.4MP runs); block-swap vs. peak memory; fal.ai offload for jobs that won't fit
- Minimal API workflow examples plus golden rules that prevent classic agent failures (assuming nonexistent model files, submitting UI graph format to /prompt, forgetting a Save node)
Usage: clone the repo, hand it to your agent, and say "read the README and set me up" — it pastes the config, installs the skill, and smoke-tests the connection.
The author is upfront that this is a stitching job: the MCP server is the community project artokun/comfyui-mcp (kept as default because it edits the live graph node-by-node and ships model-family expertise, key for squeezing 20GB models onto 8GB), with Comfy-Org's official comfy-mcp/comfy-skills wired up as an alternative.
