Vector Store Tool#

The Vector Store node is a tool that allows an agent to access content from a vector store.

On this page, you'll find the node parameters for the Vector Store node, and links to more resources.

Examples and templates

For usage examples and templates to help you get started, refer to n8n's Vector Store Tool integrations page.

Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five name values, the expression {{ $json.name }} resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five name values, the expression {{ $json.name }} always resolves to the first name.
