Motorhead#

Use the Motorhead node to use Motorhead as a memory server.

On this page, you'll find a list of operations the Motorhead node supports, and links to more resources.

Credentials

You can find authentication information for this node here.

Examples and templates

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

Node parameters#

Session ID: the ID to use to store the memory in the workflow data.

Node reference#

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.

Single memory instance#

If you add more than one Motorhead node to your workflow, all nodes access the same memory instance by default. Be careful when doing destructive actions that override existing memory contents, such as the override all messages operation in the Chat Memory Manager node. If you want more than one memory instance in your workflow, set different session IDs in different memory nodes.
