MOST DANGEROUS TOOLS

High Risk

The most dangerous Gmail Assistant MCP tools

Write · Medium create_draft_reply This tool creates new email drafts in Gmail, which is a reversible write operation. Write · High get_unread_and_draft_replies While fetching emails is a Read operation, the tool's primary distinguishing action is automatically creating draft replies for all qualifying emails.

2 of Gmail Assistant MCP's 3 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Gmail Assistant MCP

PolicyLayer is an MCP gateway — it sits between your AI agents and Gmail Assistant MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "create_draft_reply": {
    "limits": [
      {
        "counter": "create_draft_reply_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_unread_emails": {
    "limits": [
      {
        "counter": "get_unread_emails_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
