# Tools

> Explore the built-in tools available for your agents.

Tools extend what agents can do beyond text conversations. Each tool gives agents specific capabilities to interact with the real world.

## How Tools Work

When you make a request, the agent automatically selects the right tools. You don't need to specify which tool to use — just describe what you want.

**Example:** "Search for the latest news about AI regulations" → Agent uses **Web Search** tool automatically.

## Tool Selection

Agents select tools based on:

1. **Your request** — What you're asking for
2. **Available tools** — Which tools are enabled for the agent
3. **Connected services** — Which external services are configured

<Tip>
  You can limit which tools an agent has access to in the agent's settings. This is useful for creating focused agents that only handle specific tasks.

## Tool Results

Tool results appear inline in the conversation. Depending on the tool:

* **Search results** show as summarized findings with source links
* **Generated images** appear as inline images
* **File processing** shows extracted content or analysis
* **Browser** can show screenshots or extracted data
