ComfyUI Clipboard Nodes In-graph replacement for ComfyUI-Clipboard-Workflow-Automator.
Clipboard-Automator
In-graph replacement for ComfyUI-Clipboard-Workflow-Automator. Instead of a separate script polling the clipboard and pushing prompts to the API, these are nodes that live inside the workflow itself: when executed, they block/poll until new clipboard content appears, then output it.

Nodes
- Clipboard Image Input (wait) →
IMAGE,MASK - Clipboard Text Input (wait) →
STRING
Both take:
| Input | Meaning |
| ---------------- | ------------------------------------------------------------------------ |
| poll_interval | Seconds between clipboard checks (default 0.5) |
| timeout | Give up after N seconds with nothing new; 0 = wait forever |
| ignore_current | On the node's first run, ignore whatever's already on the clipboard (mirrors the old script's "startup skip") |
Install
cd ComfyUI/custom_nodes
git clone https://github.com/kastelan/Clipboard-Automator.git
cd Clipboard-Automator
pip install -r requirements.txt # or: pip install .
Linux additionally needs system GTK bindings for PyGObject:
sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0
Restart ComfyUI. The nodes appear under the clipboard category.
Usage
- Add Clipboard Image Input or Clipboard Text Input where you'd
normally put
LoadImage/CLIPTextEncode's text widget. - Queue the prompt. Execution pauses on that node until you copy something.
- To get continuous monitoring like the old script: enable Auto Queue (dropdown next to the Queue button in the ComfyUI UI). The graph re-runs automatically after each completion, and the clipboard node waits for the next change each time.
- Cancel/Interrupt in the UI works normally — it breaks out of the wait
loop cleanly (via
comfy.model_management.throw_exception_if_processing_interrupted).
Why this instead of the standalone script
| | Script (clipboard.py) | These nodes |
|---|---|---|
| Runs as | separate process | part of the ComfyUI graph |
| Multiple workflows | via --profile files | just build different graphs |
| Retry/dead-letter queue | yes (own HTTP calls) | not needed — ComfyUI owns execution |
| Setup | config.toml, node titles (load_clipboard_image) | drag a node in, no config file |
| Stopping mid-wait | Ctrl+C in terminal | Cancel button in ComfyUI UI |
Trade-off: while a clipboard node is waiting, that slot in the queue is occupied (same as any other long-running node) — you can't run other prompts concurrently on the same ComfyUI instance in the meantime.
