Connects Claude to BounceProtect's email validation API with three straightforward tools: validate_email for single checks, validate_emails_bulk for batches up to 100, and check_credits to monitor your balance. Uses SMTP verification under the hood to catch typos, invalid domains, and dead mailboxes before you send. Setup requires a BounceProtect API key passed as an environment variable. Reach for this when you're processing contact lists, cleaning CRM data, or building signup flows and need to verify addresses without leaving your AI workflow. Each validation costs one credit, with 100 free to start.
