MOST DANGEROUS TOOLS

High Risk

The most dangerous MCP Outlook tools

Write · Medium create_calendar_event This tool creates calendar events, which are reversible modifications to user data. Write · Low create_contact This tool creates a new contact record in Outlook, which is a write operation that modifies the Contacts folder by adding data. Write · Medium create_draft_email Creating a draft email is a reversible write operation—it stores new data (an unsent email) that can be modified or deleted. Write · High send_email Sending emails creates new messages and transmits them to recipients—a reversible write operation (emails can be recalled in some cases, but generally constitute committed communication).

5 of MCP Outlook's 17 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP Outlook

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

Rate limit write operations

{
  "create_calendar_event": {
    "limits": [
      {
        "counter": "create_calendar_event_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "download_email_attachment": {
    "limits": [
      {
        "counter": "download_email_attachment_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register MCP Outlook — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
