MCP's token waste and cost draw criticism from AI leaders

By PulseAugur Editorial · [1 sources] ·

The author argues that the current implementation of MCP (Model Communication Protocol) is inefficient and costly, despite its widespread adoption. Evidence from industry leaders like Garry Tan and Denis Yarats, along with internal Anthropic data, suggests that MCP's design leads to significant token waste by loading extensive tool schemas into context windows. This bloat not only increases costs but also degrades agent performance by reducing the context available for reasoning and tool selection. The author proposes solutions like using a proxy layer, such as their own `mcptoon` tool, or simply removing unused MCP servers to mitigate these issues. AI
