A developer identified a significant token overhead issue in MCP agents, where the LLM repeatedly received extensive JSON tool definitions, consuming a large portion of the token budget. This inefficiency, costing thousands of dollars daily at scale, stems from MCP's default implementation that sends all tool schemas regardless of relevance. The developer proposed and implemented three solutions: client-level schema pruning using embeddings to filter relevant tools, compressing schemas by replacing verbose descriptions with concise domain terms, and dynamically generating schemas based on the LLM's immediate needs rather than sending a static, comprehensive list.
