What they did
BonBook built an MCP server so travellers can search live flights in Claude with as much or as little detail as they like, pick an option and book without filling in forms, keeping points and status.
Result (as claimed)
A flight booked in about 35 seconds without leaving the chat.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Define the job
Say exactly what you want done and what the agent may and may not do on your behalf.
Share only what is needed
Give Claude the minimum files or access required. Avoid sharing passwords in chat when a safer login flow exists.
Review the plan
Ask the agent to show its plan or draft before it acts, and approve each step that has real consequences.
Check the result
Confirm the outcome yourself (order placed, request sent, document understood) and keep a record.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
