# Tool Node

The Tool node executes built-in integrations and searches, allowing workflows to interact with external data and services.

## Example Usage

### Web Search Tool

Setting the Tool Name to `web_search` creates a node that searches the internet and returns relevant results.

```
[Text Input] → [Tool Node: 'web_search'] → [Agent: "Summarize results"] → [Response]
```

## Tips

* Keep tools correctly named (e.g. `web_search`, `calculator`)
* Combine a Tool node directly before an AI node to provide real-world context for generation queries.

***

> **Pro tip:** Always pass structured output from an AI node into a Tool if the parameters require complex formatting.
