Capabilities
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

SiteCheck — questions
Answers built from our own checks of this server.
What can SiteCheck do?
It exposes 29 tools, read directly from the server on our last check. Among them: audit, chat, contacts, domain, email_check, embed and 23 more. 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 →
What is SiteCheck mostly used for?
Its tools cluster around markets and solana. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is SiteCheck 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 152 ms. The bar chart above shows every period we have measured.
How do I connect SiteCheck?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does SiteCheck need an API key?
No. SiteCheck completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 29 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is SiteCheck?
It answers our handshake in 152 ms on average, which is faster than 71% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is SiteCheck open source?
Yes — it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
