MCP Service Changelog

​

v2.9 (2026-10-22)

​

🚀 Core Update: Stateless Search Pagination Mechanism

• Stateless Pagination Token (nextPageToken):
  • Added nextPageToken in searchHotels response. Callers can pass this token in multi-turn conversations when requesting “next batch” or pagination to explore candidate hotels continuously.
• Dynamic Page Size (size):
  • Supports custom hotel count per page (default: 5, flexibly configurable from 1 to 10).
• Anti-Drift Parameter Snapshot:
  • Paged requests automatically inherit the initial query’s destination, dates, stars, and price filters, preventing LLM parameter drift during multi-turn interactions.
• Incremental Availability Probing:
  • The server utilizes real-time incremental probing, returning immediately upon matching target inventory, significantly reducing multi-turn pagination latency.

💳 Core Update: Multi-Platform Checkout & Payment Routing

• Mutually Exclusive Payment Payload by Host Environment:
  • Returns paymentUrl (Web checkout string) for web and browser environments.
  • Returns miniProgramPayInfo (Native checkout object) for WeChat Mini Program or mobile native environments.
  • Strictly mutually exclusive based on host environment, eliminating payload confusion.
• Safe Nulling for Non-Pending States:
  • For orders that are confirmed, cancelled, or expired past the 30-minute window, the payment field is safely set to null to prevent broken navigation.
• Standardized Payment Tools:
  • Synchronously upgraded createHotelBookingWithPaymentURL, getHotelOrderDetail, and searchHotelOrders to maintain uniform payment data structures.
