## Verdicts

**FlightClaw.** Hosted MCP at mcp.flightclaw.com/mcp with OAuth 2.1, PKCE and dynamic client registration, no API keys. Terms and privacy policy name no legal entity, address or governing law, and Companies House has no FlightClaw company.

**Odessia.** Odessia is a free travel concierge that books as a registered travel agent, watches prices and award seats, and keeps a public status page with a clean record since July. No outside agent can call it, standing authorisations let it pay without asking each time, and no changelog was found.

## Before you call either

### FlightClaw

1. Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move
2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking
3. Never ask for card numbers in chat. Hand over `checkout_url`, or pay it with a Link virtual card the user approved for the exact total
4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches
5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details

### Odessia

1. Don't plan to call Odessia from another agent. It answers only its signed-in owner on the web, by message or by email.
2. Check whether the owner has set a standing authorisation before assuming a booking will wait for approval.
