-Version 2 is currently in pre-alpha development, making it unstable for production use
-Requires peer dependency on Zod v4 for schema validation, adding complexity to setup
-May be over-engineered for simple context provision scenarios that don't need full MCP protocol

•Production LLM application monitoring to track performance, costs, and identify issues in real-time
•Prompt engineering and management for teams collaborating on optimizing model prompts and tracking versions
•LLM evaluation and testing to measure model performance across different datasets and use cases

•Building MCP servers that provide tools, resources, and prompts to LLM applications
•Creating MCP clients that consume standardized context from various servers
•Integrating MCP capabilities into existing Express or Hono web applications
