Can the AI fix the CSS bugs it finds?

No. The AI can only see and report on the visual state of the website through screenshots. You must apply the code fixes yourself.

Does the AI interact with buttons or forms?

No. The tools only capture static snapshots of the rendered page. The AI cannot click buttons or fill out forms to test dynamic states.

Can I audit sites that require a login?

No. The current tools capture the public-facing URL provided. They do not support authenticated sessions or navigating through login screens.

How does the AI know which viewports to use?

You tell the AI which devices or resolutions you care about in your prompt, and it uses the appropriate tool to capture those specific views.

Will the AI delete any files on my server?

No. This MCP is read-only. It only captures visual data from the URL you provide and cannot modify your website or server files.

How to audit responsive web designs with your AI

Connect ScreenshotAPI to your agent to automate visual testing. Once connected, your AI can see exactly how a site looks on a phone versus a desktop.

Ask AI about this page

Short answer

How can I use AI to check responsive web design?

Your AI uses ScreenshotAPI to take snapshots of a website at specific viewport sizes. It then analyzes these images to spot overlapping text, broken layouts, or hidden elements on mobile. You'll get a clear list of visual bugs across different devices.

Where every issue lands.

Visual audit outcomes

The AI processes the screenshots and organizes the results into these categories.

LAYOUT

Broken viewports

The AI identifies where elements overlap or bleed off the screen. You get a list of specific viewport sizes where the layout fails.

CONTENT

Text and image issues

The agent flags illegible text sizes or images that don't scale correctly. This helps you catch readability problems on small screens.

HUMAN

Manual verification

The AI flags ambiguous visual glitches that require a human eye to confirm. You decide if a minor shift is actually a bug.

REPORTS

Visual diff logs

The AI summarizes the differences between desktop and mobile renders. You receive a concise summary of the most critical visual regressions.

The workflow

What your AI does when the request arrives.

The AI handles the heavy lifting of rendering and capturing the site so you don't have to open a browser manually.

Capture desktop views
The AI takes a full-page snapshot of the target URL using the standard desktop viewport. This provides the baseline for your audit.
capture_website_screenshot
Capture mobile views
The agent switches to mobile viewports to see how the site responds to smaller screens. It captures these specific renders for comparison.
capture_mobile_view_screenshot
Analyze visual consistency
The AI compares the desktop and mobile images side by side. It looks for shifts in font size, alignment, and element positioning.
