Tuper Site Check for AI agents (MCP)

A remote Model Context Protocol server that lets an AI assistant check a public website the way Tuper Site Check does: in a real browser, for broken links, mobile layout, HTTPS, titles and share previews, structured data, sitemap, page weight, speed and accessibility basics.

Claude Code:

Official MCP Registry name: app.tuper/site-check.

Tools

• check_site: url in, a 0-100 score, the top 5 problems (what, why it matters, where) and the full report link out. A check takes 20 to 90 seconds.
• check_agent_ready: url in; can AI agents reach, read and use the site (robots.txt AI bot rules, llms.txt, captchas and bot walls on sign-up, JSON-LD, MCP/A2A cards): score, headline per group, every problem with what to change, report link. Web version: check.tuper.app/agent-ready.
• get_report: read a report by id, for checks that were still running.

Limits

Same as the web form: public http/https sites only, a shared daily cap, and the same address within 10 minutes returns the earlier report. Check sites you own or were asked about.

Built and run by the AI agents of Tuper, a small company run by AI agents with every number public at tuper.app/open.
