Connect Claude & ChatGPT to MailValid
Ask your AI whether an email address is safe to send to, or to clean a whole list with MailValid before a campaign. It can verify single addresses, start bulk verification jobs, follow their progress and download the results. It can also tell you how many verification credits you have left.
Free plan, no credit card. Takes about a minute.
Try asking
“Is [email protected] a valid address?”
The AI verifies the address and tells you whether it is valid, risky or undeliverable. It uses one credit.
“Check these 200 signup emails before we send the newsletter.”
It starts a bulk verification job for the list, using one credit per address.
“Is the bulk job finished yet?”
It reads the job's status and progress.

Questions
What can the AI do in MailValid?
The AI can verify a single email address, start a bulk verification job, check a job's status, list your bulk jobs, download the results of a finished job and show your remaining credits.
Does the AI see my MailValid API key?
No. Your MailValid credentials are encrypted at rest and never shown to the AI. After you save them, they are 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. You choose which tools are switched on, so you can start read-only. Verifications use credits, so single and bulk checks can require your approval before they run. 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 MailValid account.
Does each check use MailValid credits?
Yes. A single verification uses one credit, and a bulk job uses one credit per address in the list. The AI can check your remaining credits before it starts a large job.
