# Tool Node

> Connect to external services and APIs

Add [Dify tools](/en/2.7.x/use/workspace/tools) to your workflows as standalone nodes.

This lets your workflows interact with external services and APIs to access real-time data and perform actions, like web searches, database queries, or content processing.

**To add and configure a tool node**:

1. On the canvas, click **Add Node** > **Tools**, then select an action from an available tool.

2. Optional: If a tool requires authorization, click **Set Up Authorization** when prompted and enter its credentials.

3. Complete any other required tool settings.
