AI Tool Response

Return a response for a tool invocation that started from an AI Tool node.

Where to Find It

In the Flow Editor, in the left palette look under AI Gateway, then drag Tool Response onto your canvas.

AI Tool Response configuration with the Output property.

What It Does

The Tool Response node sends the tool result back to the original AI Generate request so the model can continue with the returned data.

Configuration

1. Name (optional) - Provide a friendly label for the node.

2. Output (required) - The property containing the tool result.

   • Use a msg reference (default: msg.payload) to return a computed result.

   • Use a static string when you want to return a fixed response.

Outputs

• Strings are returned directly.

• Objects are stringified before being returned to the model.

Use this node at the end of a tool execution path so the model receives the tool output.
