# buy_save_traveler

> Save the traveller (passenger) details a flight booking needs: legal first + last name (as on their government ID), date of birth (YYYY-MM-DD), gender, contact…

Connect to `https://mcp.agentcard.sh/mcp` with the **user's connection token** (or a `buy_token` for org-owned accounts).

**Behavior:** idempotent.

<Note>Not in the default `tools/list`. It is still callable by exact name, and appears when the client sends the `x-expert-tools: 1` header.</Note>

## What it does

Save the traveller (passenger) details a flight booking needs: legal first + last name (as on their government ID), date of birth (YYYY-MM-DD), gender, contact email, and phone. REQUIRED once before booking a flight — collect these from the user, confirm them back, then call this. Stored securely (DOB encrypted at rest) and reused for future bookings; saving again overwrites. Not needed for food/grocery merchants.
