Google Cloud Vertex AI Agent Engine

Vendor key: gcp_vertex. For how source fields and scan configs fit together, see Agent Discovery Integrations.

Lists every agent deployed to Vertex AI Agent Engine in one GCP project and region. To cover more regions or projects, add one source for each.

Source fields

Field	Required	Sensitive	Default	Description
`project_id`	Yes	No		The GCP project ID (for example `my-gcp-project`), not the project name or number.
`location`	No	No	`us-central1`	The region to scan.
`service_account_key`	Yes*	Yes		The full JSON key of a GCP service account.

* Required unless your Arthur engine runs on GCP and has been configured to use its own Application Default Credentials (ARTHUR_ENGINE_GCP_VERTEX_ALLOW_ADC=true).

Scan config

Setting	Value
`query`	`""`
`query_language`	`none`
`lookback_window_seconds`	Ignored. Every scan returns every agent engine in the region.

Required permissions

The service account needs only aiplatform.reasoningEngines.list on the project. The predefined role roles/aiplatform.viewer includes it. For least privilege, grant a custom role with just that permission.
