classify
classify_asset
Classify an input as a domain, IP, package, repository, etc. No network calls — instant response. Useful for understanding what an asset is before performing a full lookup.
lookup
lookup_security_contact
Find security reporting channels for responsible vulnerability disclosure. Takes a domain, IP, URL, package name, repository, container image, mobile app, hardware device, browser extension, desktop app, or organization name. Returns bug bounty programs, security.txt contacts, VDP links, abuse contacts, and national CERT fallbacks sorted by confidence. This is informational only — not legal advice.

Lookup Disclose Io — questions

Answers built from our own checks of this server.

What can Lookup Disclose Io do?
It exposes 2 tools, read directly from the server on our last check. Among them: classify_asset, lookup_security_contact. 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 Lookup Disclose Io 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 323 ms. The bar chart above shows every period we have measured.
How do I connect Lookup Disclose Io?
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 Lookup Disclose Io need an API key?
No. Lookup Disclose Io completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Lookup Disclose Io?
It answers our handshake in 323 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
