## Transports

Streamable HTTP

## Authentication

Google Cloud authentication: OAuth 2.0 using Application Default Credentials (ADC) in supported Google clients, or a client OAuth ID/secret or bearer token in compatible third-party clients. The principal needs mcp.tools.call plus the underlying product permissions; API key authentication is only available for services that explicitly support it.

## Tools

- **explore_schema**: Explores the topology schema via multi-hop BFS traversal from starting label names within a domain schema.
- **generate_discovered_resources_topology**: Generate the topology for all discovered (including non-registrable) resources for given project based on the view option and filters. Constructing filters requires valid node labels, edge labels, and properties, which can be retrieved in bulk via get_schema or incrementally explored via explore_schema .
- **get_domain**: Retrieve details about a specific, named topology domain.
- **get_schema**: GetSchema returns the complete schema (supported node and edge labels and properties for a domain) to construct filters. Alternatively, explore_schema provides incremental exploration of the topology schema.
- **list_domains**: ListDomains method returns all available topology domains in a specific location.
