A developer encountered significant cost increases due to the Model Context Protocol (MCP) when integrating AI agents, where tool schemas consumed an excessive amount of tokens. The author found that a single server's schema alone could add 42,000 tokens to a request, leading to a 37% bill increase. To combat this, four optimization strategies were implemented: lazy-loading server schemas only when relevant, minimizing tool descriptions, and server-side filtering of tools to only expose necessary ones.
