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.

domain
check_domain
Check a domain only (no local part; anything containing "@" is refused): disposable (the domain or a parent domain is on the disposable-email-domains list), free webmail provider, look-alike (confusable) domain and a typo suggestion. Use this when you do not need the part before the @. Read-only. Same engine, keys and limits as GET /v1/domain/{domain}.
email
check_email
Check one email address against the disposable-email-domains list (CC0): disposable (domain or a parent domain is listed), role address (info@, admin@ …), free webmail provider, look-alike (confusable) domain, practical syntax, and a one-character typo suggestion for big webmail domains. List-based and offline: no MX/DNS lookup, so a valid format does not mean the mailbox exists. The address is sent in a POST body and not stored or logged. Read-only. Same engine, keys and limits as POST /v1/check.
meta
get_meta
Return the service version and build, the disposable-list version, domain and allowlist counts, the last refresh time, the upstream source and licence (CC0), and the current limits. Does not count as a check. Read-only. Same data as GET /v1/meta.

BurnerCheck — questions

Answers built from our own checks of this server.

What can BurnerCheck do?
It exposes 3 tools, read directly from the server on our last check. Among them: check_domain, check_email, get_meta. 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 BurnerCheck working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 97 ms. The bar chart above shows every period we have measured.
The registry lists BurnerCheck as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect BurnerCheck?
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 BurnerCheck need an API key?
No. BurnerCheck 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.
