Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

built

check_ai_built_app

Reads the public pages and public JavaScript of a web app (typically built with Lovable, Bolt, v0, Replit or similar) and reports exposed API keys, public source maps, missing security headers, stale deploys, missing error monitoring and AI model calls made from the browser. Passive check: it never logs in, submits forms or probes private routes.

diagnose

diagnose_shopify_store

Reads the public pages of a Shopify store and reports whether it offers social login and a wishlist, how many products show as sold out, and whether it runs storefronts for several countries. Reads only public pages.

site

check_site_email_security

Checks whether a domain's email is likely to reach the inbox (SPF, DKIM and DMARC records, mail servers) and whether the website has basic security in place (HTTPS, security headers, WordPress exposure, Lovable/Supabase setup). Reads only public DNS records and the public home page. The report is written in Portuguese.

RealMarket Site Check — questions

Answers built from our own checks of this server.

What can RealMarket Site Check do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_ai_built_app, check_site_email_security, diagnose_shopify_store. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is RealMarket Site Check working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 701 ms. The bar chart above shows every period we have measured.

How do I connect RealMarket Site Check?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does RealMarket Site Check need an API key?

No. RealMarket Site Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is RealMarket Site Check?

It answers our handshake in 701 ms on average, which is faster than 12% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
