This is a straightforward B2B data enrichment tool that runs without authentication. You get company lookups by domain, email validation to check if addresses are deliverable, email pattern detection to figure out how organizations structure their addresses, and basic domain information queries. It's the kind of server you'd add when you're building sales tools, cleaning contact lists, or need to enrich lead data without signing up for enterprise APIs. The streamable HTTP transport means you can drop it into Claude without managing local processes, and the zero auth setup removes friction when you just need quick company or contact data.
