What it does
MCP server for the Verifox API, which verifies email deliverability and finds business email addresses. Useful for developers building applications that need to validate emails or locate contact information at companies.
- Verify whether a single email address is deliverable and check for catch-all, disposable, or role-based accounts.
- Bulk-verify a list of email addresses and retrieve delivery scores for each one.
- Find business email addresses by providing a person's name and company domain.

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.
