Dynamic Tool Retrieval: Scaling Agent Tool Registries Beyond 100 Tools
When an agent has access to hundreds or thousands of tools, listing all of them in the context window is token-wasteful and degrades model performance. Dynamic tool retrieval — selecting the relevant subset of tools at runtime using embeddings or a lightweight classifier — is how production agentic platforms scale.
What is a Tool Registry in AI Agent Systems?

Instead of hardcoding tool availability, a registry lets agents discover, select, and invoke tools dynamically, making agent systems far more flexible and maintainable.
