It combines intent overlap scoring, state-aware gating, and compact schema summaries to reduce per-turn tool tokens in a simulated multi-server benchmark. ## Semantic links ## Key Takeaways - Frames the MCP/Tools Tax as recurring token cost from eager schema injection. - Uses ISO scoring, gating, and lazy schema promotion to limit context growth. - Reports large token reductions in simulation, with downstream metrics projected from those measurements. ## Context The paper targets the context and latency costs of exposing many tools to agentic LLM workflows. ## Implications Protocol-level tool selection can substantially reduce per-turn overhead in large agent systems. ## Original Reference - Title: Tool Attention Is All You Need: Dynamic Tool Gating and Lazy Schema Loading for Eliminating the MCP/Tools Tax in Scalable Agentic Workflows - Authors: Anuj Sadani, Deepak Kumar - URL: http://arxiv.org/abs/2604.21816v1 - Published: 2026-04-23T16:10:00Z - Source file: /home/rich/wiki/ai-research/raw/papers/2026-04-23_16-10-00Z_ToolAttentionIsAllYouNeed_DynamicToolGatingandLazy.md [[raw/papers/2026-05-09_1706.03762-attention-is-all-you-need.md]] ## Related Concepts - [[concepts/ai-agents/agentic-workflows-hub.md|Agentic Workflows Hub]] - [[concepts/software-development/software-development-hub.md|Software Development Hub]] - [[concepts/llm-models/llm-models-hub.md|LLM Models Hub]] - [[concepts/evaluation-benchmarks/evaluation-benchmarks-hub.md|Evaluation Benchmarks Hub]]
