What it does
MCP server that finds and verifies work email addresses for contacts using your own provider API keys. You supply keys to email providers, set spending limits, and get back email addresses with attribution to which provider found them and exact costs spent from your accounts.
- Build a prospect list by submitting contacts with company domain or LinkedIn URL and receiving verified work emails with cost attribution per provider.
- Control email finding costs by setting per-provider spending caps and choosing which providers to query in what order.
- Compare provider performance on your own contact set by seeing which providers successfully found emails and how much you spent at each.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
