Parameters from the server's own tool schema.

RISK

Why addDocumentTab is rated Medium

Adding a tab to a Google Doc creates new document structure that can be undone or deleted. This is a write operation (creates/modifies data reversibly) rather than read (no retrieval), execute (no code/command execution), destructive (reversible action), financial (no money movement), or other.

From the tool's definition Tool name 'addDocumentTab' and description 'Add a new tab in a Google Doc' indicate creation of new content within a document. This is a reversible modification operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs addDocumentTab safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Google Drive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For addDocumentTab, this is the rule to start with:

addDocumentTab Rate-limited

addDocumentTab stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "addDocumentTab": {
      "limits": [
        {
          "counter": "adddocumenttab_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Google Drive, apply this rule, and every addDocumentTab call is checked against it from then on.
