# LocalCloud service matrix for agents

Use this matrix to decide which localhost endpoint an agent should configure before running SDK, CLI, Terraform, or integration checks. Service-specific HTML pages are canonical for human-facing capability detail.

Default LocalCloud agent workflows require no GCP account, no Google credentials, no service-account keys, and no billing project. If a service is partial or planned, stop and document the gap instead of using real Google Cloud as a fallback.
