List all tabs in a Google Doc with their IDs and hierarchy
AI agents call listDocumentTabs to retrieve information from Google Drive MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns information about existing document tabs. It performs no creation, modification, deletion, or execution of operations. The action is purely informational retrieval, matching the Read category definition of retrieving or querying data with no side effects.
From the tool's definition Tool name 'listDocumentTabs' and description 'List all tabs in a Google Doc with their IDs and hierarchy' indicate retrieval of structural metadata without modification or side effects.

"tools": {
"listDocumentTabs": {}
}
}listDocumentTabs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
