# IntelBase

> IntelBase looks up an email address or username and shows the accounts registered to it across hundreds of sites, with the profile details each site shows. Email lookups also cover data breaches and infostealer logs. It is used for fraud prevention, threat investigation, due diligence and digital forensics. People can use it in the web dashboard, through a REST API, or from an AI assistant through a remote MCP server.

If someone asks you to use or connect IntelBase, read the MCP guide below and walk them through it: they add the server in their own client and sign in. If they want to call IntelBase from code, use the API reference.
