Perceptdot

AI Visual QA. visual_check(url) screenshots a page with Cloudflare Browser Rendering and finds layout bugs with Gemini 2.5 Flash. Use it from any MCP client (Claude Code, Cursor, Windsurf, Cline) or as a GitHub Action.

A typical page takes about 7 seconds, long pages up to ~20 seconds. Fully headless: no desktop or GUI needed.

Quick start

1. Get a free API key at perceptdot.com (100 credits per month, no card).
2. Add the remote MCP server. The key goes in the X-Percept-Key header.

Claude Code

claude mcp add --transport http perceptdot https://mcp.perceptdot.com/mcp --header "X-Percept-Key: YOUR_KEY"

Cursor (~/.cursor/mcp.json)

{"mcpServers":{"perceptdot":{"url":"https://mcp.perceptdot.com/mcp","headers":{"X-Percept-Key":"YOUR_KEY"}}}}

Windsurf (~/.codeium/windsurf/mcp_config.json)

{"mcpServers":{"perceptdot":{"serverUrl":"https://mcp.perceptdot.com/mcp","headers":{"X-Percept-Key":"YOUR_KEY"}}}}

Then ask your AI: "Check https://your-site.com with perceptdot".

What it checks

• DOM audit (deterministic): viewport overflow, broken images, parent overflow, low contrast.
• AI review: each tile of the page is reviewed by Gemini 2.5 Flash for layout problems, with severity (high / medium / low).

Desktop (1280px), tablet (768px) and mobile (375px) viewports are supported.

---

Pricing

1 credit = 1 tile = a 1280×1600 px slice of the page. A short page is about 1 credit, a long landing page about 3–5 credits.

Privacy

Screenshots are not stored. They are sent to Google (Gemini API) and Cloudflare (Workers AI, fallback) for analysis. Analysis results (summary and issues, never screenshots) are cached for up to 10 minutes per URL and viewport. Google may use data sent to unpaid Gemini API tiers to improve its products, so do not check pages that contain personal data.
