// payment firewall for AI agents · MCP

Let your agents pay.
Never your bank.

An MCP server that returns a one-time UPI VPA when your rules allow — and denies everything else before it ever touches your bank.

01HOW IT WORKS
01
Agent hits checkout

The agent calls AiPay's request_payment_vpa MCP tool with the amount, the checkout URL and a screenshot.

02
AiPay runs your rules

Regex rules plus a visual context check decide allow vs deny on every request — before a single rupee can move.

03
You approve in your UPI app

On allow, AiPay returns your category's VPA and the merchant fires a normal UPI Collect you approve in GPay or PhonePe.

02RULES

Plain English in.
Precise regex out.

Describe what agents may and may not pay for. AiPay compiles it into a filter that runs on every request — block or allow, by site, description or amount. Report a charge and it writes the rule for you.

03SECURITY
Zero-trust firewall

AiPay sits between the agent and your bank; it never holds card or bank credentials.

Per-integration keys

Every agent gets its own key you can disable or revoke instantly.

Category routing, no KYC

Map spend categories to your existing UPI IDs to isolate risk.

04SETUP

Live in two lines of config

Paste into your client's MCP config, restart, and the agent gets a pay tool. It only ever holds an API key that can ask — never your bank.
