Questions

What can the AI do in Hunter?

The AI can find and verify email addresses, search a domain, count emails, enrich people and companies, find company domains and discover companies. It can read your leads, lead lists, sequences, sequence recipients and stats, check your account and remaining credits, and save leads.

Does the AI see my Hunter API key?

No. Your Hunter 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. You choose which tools are switched on. Finding and verifying emails and saving leads can require your approval before they run, so the AI does not spend searches or change your leads without you. 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 Hunter account, and searches and verifications use your Hunter credits.

Can the AI check how many Hunter credits I have left?

Yes. The AI can read your Hunter account details, including your plan and remaining search and verification credits. Counting the emails for a domain is free and does not use credits, so the AI can check whether a domain is worth searching first.
