Questions
What can the AI do in mailfloss?
It can verify single email addresses, submit batch verifications and read their status and results, and list verification jobs, usage reports, integrations and connections, team members, webhooks and the account timeline. It can connect, test, update, sync and disconnect email platform connections, manage keyword rules and webhooks, and erase stored verification records.
Does the AI see my mailfloss API key?
No. You paste your mailfloss API key into PipMCP once. It is encrypted at rest, never shown to the AI and never shown again after you save it. The AI only gets the results of the tools you have switched on.
Can I control what the AI is allowed to do?
Yes. Switch on only the tools you want, for example single verifications and reports. Risky actions, like canceling a batch, disconnecting an email platform or deleting a webhook, can require your approval before they run. Every tool call is logged.
Does it work with ChatGPT?
Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and 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, and you do not need a credit card to start. Paid plans are billed per completed task. You also need your own mailfloss account.
Where do I find my mailfloss API key?
In the mailfloss dashboard, go to Settings > API and copy your API key. It starts with mf_live_ and is scoped to your organization, so the AI works with that organization's jobs, connections and reports.
