This post delves into the engineering challenges that arise after deploying Multi-Tool Calling Protocol (MCP) servers, moving beyond initial setup to production realities. Key issues include tool overload leading to agent confusion and reduced reliability, context window management becoming an infrastructure concern, and the difficulty of ensuring deterministic tool calls due to ambiguous descriptions. The article also highlights that MCP servers evolve into complex distributed systems requiring attention to state management, observability, and scaling. AI
