Lists all tabs in a Google Document, including their hierarchy, IDs, and structure.
AI agents call listDocumentTabs to retrieve information from Google Workspace MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns metadata about document structure without creating, modifying, deleting, or executing anything. It is a pure read operation that retrieves information about an existing resource. The low severity reflects minimal blast radius—accessing this information alone does not enable harmful actions without subsequent write/execute/destructive operations.
From the tool's definition Tool name 'listDocumentTabs' and description 'Lists all tabs in a Google Document, including their hierarchy, IDs, and structure' indicate a retrieval operation with no modification, deletion, or execution of code.

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Workspace MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for listDocumentTabs:
{
"version": "1",
"default": "deny",
"tools": {
"listDocumentTabs": {}
}
}listDocumentTabs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists all tabs in a Google Document, including their hierarchy, IDs, and structure. It is categorised as a Read tool in the Google Workspace MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Google Workspace MCP Server MCP server in PolicyLayer and add a rule for listDocumentTabs: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Google Workspace MCP Server. Nothing to install.
listDocumentTabs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the listDocumentTabs rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for listDocumentTabs. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
listDocumentTabs is provided by the Google Workspace MCP Server MCP server (sputnicyoji/google-workspace-mcp-with-script). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Google Workspace MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
