## Canonical Answer

The ChatGPT app gives users a familiar place to start sessions and review payment-related state while Payrail Agent keeps protected values outside model context. Use the Payrail Agent ChatGPT app to start sessions and review requests, approvals, and Payrail Agent Card state. Protected payment and identity data stays behind Payrail Agent requests instead of entering LLM-visible context.

## What It Is For

The ChatGPT app is a cross-platform Payrail Agent client. It can show Payrail Agent Card state, payment sessions, requests, top-up flows, and approval UI.

## MCP Role

The app exposes Payrail Agent flows over MCP, so ChatGPT can start or continue a session while the backend keeps request handling.

## User Control

Payment approvals and protected-data requests still go through Payrail Agent. Users may choose chat convenience for reusable Memory facts, but raw secrets and card values typed into ChatGPT are model-visible and cannot be retroactively protected by Payrail Agent.
