Key points

  • MCP simplifies AI-tool integration, but each tool definition continuously occupies context window, wasting input tokens.
  • "Tool Tax" mainly comes from two sources: input context overload and output intermediate result redundancy.
  • Optimizations like Code Mode, pre-fetching, and native CLI can reduce token consumption by over 98%.
  • Clear tool naming and description reduce model mis-calls and loop attempts, saving costs.
