AI agents call list-tabs to retrieve information from MCP-Google-Doc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'list-tabs' indicates it retrieves or enumerates tabs (likely document sections or sheets) without creating, modifying, or deleting data. This is a read-only query operation with no side effects. While the description is empty, the naming convention and context of sibling tools provide sufficient evidence.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-Google-Doc, and nothing reaches the server without passing your rules. This is the rule we recommend for list-tabs:

"version": "1",
"default": "deny",
"tools": {
"list-tabs": {}
}
}list-tabs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
