NIGHT ONE
The day ComfyUI opened its MCP connector, I had an agent running a working video pipeline by that night.
- Role
- Solo: direction, integration, build
- Format
- Agentic creative pipeline + 33-second build film
- Year
- 2026 · Day one of the ComfyUI MCP public beta
- Made with
- ComfyUI MCP (Comfy Cloud) · Claude Cowork (Anthropic) · Seedance 2.0 · LTX-2.3 · ComfyUI audio generation
- Status
- Built and published the same day
- Note
- Independent build. Not commissioned by ComfyUI or Anthropic.
“In one session he compared three video models on the same prompt, saved a reusable workflow, generated an original music bed, and built a custom title card. Zero to finished, in a night.”
“The thing I judge a launch by is what people build in the first week. This time, that started night one.”
Brief
ComfyUI is a node-graph engine for generative image, video and audio. The day it opened an MCP connector in public beta, letting an AI agent drive the graph directly, I set myself a brief: connect it the day it ships, and don’t stop until a real pipeline runs.
Director’s statement
The fastest way to understand a new tool is to make something real with it before anyone has written the tutorial. By the end of the night the agent had run several video models so I could compare them side by side, saved the pipeline as a workflow I could run again, generated an original music bed, and built a title card. The agent did the wiring. I decided what was worth keeping.
Three decisions
-
01
Let the agent drive.
The graph is built and run by tool calls, not mouse clicks.
-
02
Compare before you commit.
Several models, side by side, then one select.
-
03
Save the night.
The pipeline became a reusable workflow, so the next build starts where this one ended.
Outcome
- Time-to-activation
- Same day the connector opened: zero to a working agentic pipeline in one session.
- ComfyUI cofounder Robin Huang wrote an original post about the build, and the ComfyUI company page reposted it.
- The name Night One comes from that post. Night One is now a recurring practice: when a tool drops, build something real that day.
