- Sampling enables servers to request LLM-generated content from clients for personalized recommendations
- Progress notifications provide real-time updates for long-running operations like flight searches
- Each user session runs in dedicated microVM with isolated resources and persistent context
- Feature available across fourteen AWS regions globally
These stateful MCP features enable complex, interactive agent workflows beyond simple request-response patterns.
