# Tools

## Overview

Tools allow ElevenLabs agents to perform actions beyond generating text responses. They enable agents to interact with external systems, execute custom logic, or access specific functionalities during a conversation. This allows for richer, more capable interactions tailored to specific use cases.

ElevenLabs Agents supports the following kinds of tools:

::::card-grid
:::card{title="Client Tools" href="/guides/elevenagents-customization-tools-client-tools"}
Tools executed directly on the client-side application (e.g., web browser, mobile app).
