Title: Tool Attention Is All You Need: Dynamic Tool Gating and Lazy Schema Loading for Eliminating the MCP/Tools Tax in Scalable Agentic Workflows

Source: http://arxiv.org/abs/2604.21816v1

Summary:

This paper introduces a middleware-layer mechanism that reduces tool-related token overhead by 95% through dynamic gating and lazy schema loading. It provides a critical efficiency breakthrough for scaling agentic systems to support hundreds of tools without exhausting context limits or sacrificing reasoning quality.
