🖥️ Screen & Visual¶

The capture_screenshot tool lets Claude see your screen — enabling a whole new class of interactions.

macOS permissions

Grant Screen Recording permission to your terminal in
System Settings → Privacy & Security → Screen Recording

Basic Screen Awareness¶

Take a screenshot of my screen and tell me:
1. What application is in focus?
2. How many windows are visible?
3. What is the main content on screen?

Screen + Notes Combo¶

Take a screenshot, describe what's on screen in one sentence,
then add that description as a note.

Screen + Memory¶

Take a screenshot and save to memory what you observe about my current workspace setup.
Later I can ask: "What was on my screen earlier?"

Screen + Web Search¶

Take a screenshot. If there's any application, code, or topic visible that you can identify,
search the web for the latest documentation or news about it.

Screen + Analysis¶

Take a screenshot and use the analyze_topic prompt
to analyze whatever main subject is visible on screen.

Accessibility Helper¶

Take a screenshot and describe everything visible in detail,
as if explaining it to someone who cannot see the screen.

Code Review Mode¶

Take a screenshot of my screen.
If you can see any code, review it and suggest improvements.
If no code is visible, tell me what is there instead.

Workflow Documenter¶

Take a screenshot.
Then add a note describing what I appear to be working on,
formatted as: "Working on: [topic] — [brief description]"

How the image gets to Claude

The screenshot is captured as a PIL image, compressed to JPEG at 60% quality (keeping it under ~1 MB), and returned as a FastMCP Image object. Claude receives it as a base64-encoded inline image — no file upload needed.
