Periscope MCP server

Periscope is a helper that gives your AI a set of website testing skills. Instead of just chatting, your AI can open a web page, click around, fill in forms, log in, and tell you what passed or failed. It is handy for anyone who has to check a website before launch or keep an eye on it afterward, even if you are not a tester.

What this MCP server does

You ask your AI to check a website, like whether a page loads or a form works. The AI calls Periscope, which opens the page in a headless browser (a browser with no visible window). Periscope clicks, types, and checks things, then hands back clear answers, screenshots, and a list of problems. Your AI reads that and tells you what it found in the chat.

What you can do with it

• Test a single web page and get a screenshot plus a list of issues
• Crawl a whole site and audit every page it finds
• Fill in forms automatically with realistic test data
• Log into a site and keep that login for later tests
• Check accessibility, SEO, and AI-readiness of pages
• Run Lighthouse performance scores
• Mock network responses to test how a page behaves

Try asking your AI

• “Test https://example.com and tell me what is broken”
• “Crawl my site and run a full audit, then save a report”
• “Log into my app with the saved login and check the dashboard loads”
• “Check the accessibility of the signup page”

What it gives back to you

You get back clear answers, not just screenshots. For example, a check might say passed: true or false with the actual value it found. You also get lists of issues, saved report files, and screenshots you can look at. Everything shows up in your chat as text and file paths.
