Tool that runs JavaScript

Usage and specifics

Connect this tool to an agent tool port. name and description help the model select it; configure sources, templates and limits before calling. requireApproval, where available, controls operations requiring approval.

Technical type : ai_tool_code. Runtime : nodulz.

Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the credentials guide if a remote source or execution target requires access.

Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

Parameter	Type	Default	Values / limits
`name`	`string`	`"code_tool"`	-
`description`	`string`	`"Run JavaScript code"`	-
`script`	`string`	`"return args;"`	-
`parametersJson`	`string`	`""`	-
`timeoutMs`	`number`	`5000`	-; ≥ 100
`requireApproval`	`boolean`	`false`	-

Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

json

{
  "name": "code_tool",
  "description": "Run JavaScript code",
  "script": "return args;",
  "parametersJson": "",
  "timeoutMs": 5000,
  "requireApproval": false
}

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
