Bouncer Email Verification MCP Server

ClaudeCommunityby Bouncer

Bouncer brings professional email verification straight into Claude. Ask in plain language, for example "check these addresses" or "clean this list before Friday's campaign", and Claude verifies them with Bouncer and immediately makes sense of the results. No exports, no CSV uploads, no switching tabs. Verification and analysis happen in a single step. WHAT YOU CAN DO - Verify a single address in real time and get the result in seconds - Verify a handful of addresses instantly, or whole lists of up to several thousand in one batch - Check domains: does it accept mail, is it catch-all, free or disposable? - Run a toxicity check to catch addresses from data breaches, spam traps and known abusers - Check your remaining credits without opening the dashboard WHY IT'S DIFFERENT Claude doesn't just trigger the verification, it understands the results. It can split a list into safe and risky addresses, explain why a specific email would bounce, recommend what to remove before a campaign, and turn everything into a table or a CRM-ready CSV. You can keep asking follow-up questions: "Which of these are role-based?", "What percentage of the list failed?", "Prepare a version for import." Claude picks the right verification method on its own: real-time for one address, synchronous for a few, and a single complete batch for lists. You don't need to know or configure any tools. SAME RESULTS AS THE BOUNCER APP AND API Every address gets one of four statuses (deliverable, risky, undeliverable, unknown) plus quality flags: disposable, role-based, free provider, catch-all and full mailbox. Unknown results don't consume credits. SECURE BY DESIGN - Standard OAuth 2.1: no API keys or passwords pasted into the chat - Every connection appears as a dedicated, labeled API key in your Bouncer dashboard - Revoke access instantly by deactivating the key - Verified addresses are not stored by the connector; only anonymized tool-usage statistics are collected
