Connect Claude & ChatGPT to Email Hippo
Ask your AI whether an email address is real before you send to it or accept a sign-up. It checks the address with Email Hippo and tells you if it is deliverable, what the mailbox and domain checks found, whether it is a disposable, role or free-mail address, and its risk score.
Free plan, no credit card. Takes about a minute.
Try asking
“Is [email protected] a real, deliverable address?”
The AI verifies the address and tells you whether it is deliverable, with the mailbox and domain check results.
“Is this sign-up using a throwaway email?”
It checks the address and reports whether it is flagged as disposable.
“Check these five addresses from the event list before I import them.”
It verifies each address in turn and sums up which ones look deliverable and which do not.

Questions
What can the AI do in Email Hippo?
The AI can verify one email address at a time. For each address it gets deliverability, mailbox and domain checks, disposable, role and free-mail flags, and a risk score. It does not send any email.
Does the AI see my Email Hippo credentials?
No. Your Email Hippo API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.
Can I control what the AI is allowed to do?
Yes. Email Hippo has one tool, verify_email, which only reads. You can switch it off at any time or require your approval before each check. Every tool call is logged.
Does it work with ChatGPT?
Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.
What does it cost?
PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Email Hippo account. Checks run through your own Email Hippo MORE API key.
Can the AI check a whole list?
Yes, one address at a time. Give the AI a short list and it runs a check for each address and sums up the results. Each address is a separate call.
