Gemini Enterprise Registration

Requires: A deployed agent. For Agent Runtime, deployment_metadata.json (created by agents-cli deploy) enables auto-detection. For Cloud Run or GKE, provide the agent card URL and flags directly.

Prerequisites

1. Agent must be deployed — the agent must be running and reachable
2. Gemini Enterprise app must exist — Create one in Google Cloud Console → Gemini Enterprise → Apps before registering
3. deployment_metadata.json (Agent Runtime only) — Created automatically by agents-cli deploy; contains the agent runtime ID, deployment target, the A2A flag, and the agent directory
4. Text-based agent — Live/voice (bidi) agents are not supported by Gemini Enterprise, which has no /run_live transport. Register a text-based agent instead.

Required Permissions for A2A on Cloud Run

• roles/run.servicesInvoker granted to the Discovery Engine service account (service-<PROJECT_NUMBER>@gcp-sa-discoveryengine.iam.gserviceaccount.com) on the Cloud Run service.
