Summary
Connects to the emailfinder.dev API to look up verified professional email addresses without leaving your AI assistant. You get five tools: search by name and domain, extract from LinkedIn profiles, pull all emails at a company, find decision makers by role, and validate deliverability. The first four consume credits only when they return results (1 credit for individual lookups, 5 for bulk operations), while validation is free. Useful when you're doing outreach research, building contact lists, or need to reach someone specific at a company. Requires an API key from emailfinder.dev and runs via npx in Claude Desktop, Cursor, or Kiro.
