Connect Claude & ChatGPT to OnSefy
Ask your AI whether a new signup looks risky before you approve it. It sends the email or phone number, and optionally the name, IP address and user agent, to OnSefy and returns the risk result. On paid OnSefy plans it can also run advanced checks and a VPN check.
Free plan, no credit card. Takes about a minute.
Try asking
“Check the risk for a new signup: [email protected] from IP 203.0.113.7.”
The AI sends the email and IP address to OnSefy and shows the risk result.
“Is +45 12 34 56 78 a risky phone number for a new account?”
It checks the phone number, with country code, and shows the result.
“Here are five signups from today. Which ones look risky?”
It checks each signup in turn and puts the results side by side.
What your AI can do
Signup risk checks
Check a new signup or user for fraud risk from an email or phone number, with optional name, IP address and user agent.
Paid plan options
On paid OnSefy plans, turn on advanced checks and a VPN check for a signup.
One focused tool
The connection has a single tool, check_signup_risk, so the AI has one clear job.
“Run a VPN check on [email protected], IP 198.51.100.4.”
It runs the check with the VPN check turned on. This works on paid OnSefy plans only.
“Check this signup with name, email and user agent.”
It sends the name and user agent along with the email, so OnSefy has more to go on.
“Check the email on this support request before we reset the account.”
It checks the email address and shows the risk result, so you can decide whether to go ahead.

Questions
What can the AI do in OnSefy?
The AI can check a new signup or user for fraud risk. It needs an email or a phone number with country code, and it can add the name, IP address and user agent. Advanced checks and the VPN check work on paid OnSefy plans. The tool only runs checks and does not change anything in your OnSefy account.
Does the AI see my OnSefy API key?
No. Your OnSefy 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. There is one tool, and you can switch it off at any time. Each check sends the signup details you give the AI to OnSefy. You can require your approval before a check runs, and 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 OnSefy account.
Why does OnSefy ask for an API host?
OnSefy uses a different address for its free and paid plans. Enter 'api' if you are on a paid plan or 'free-api' if you are on the free plan, and PipMCP sends the checks to the right place.
