READgoogle.list_capabilities

• Contract tier: agent_ready
• Risk: read
• Catalog version: google-2026.07.12.2

Use this local read-only navigation tool to return Google ToolManifest counts or the complete lossless provider-owned descriptor catalog. This is a local, read-only navigation operation. It requires a valid MAD MCP Portal grant but does not contact Google or require Google OAuth credentials.
