MOST DANGEROUS TOOLS

Critical Risk

The most dangerous VaultAssist tools

Destructive · High batch_delete_gmail_emails This tool permanently removes email messages without possibility of recovery (beyond Gmail's trash bin with limited retention). Destructive · High clear_completed_tasks While the description says tasks are 'marked as hidden' rather than permanently deleted, 'clearing' completed tasks is a bulk irreversible operation that removes visibility of all completed tasks at once. Destructive · High delete_event Deleting a calendar event cannot be undone and removes data permanently. Destructive · High delete_gmail_email Deleting email is irreversible and destroys data.

45 of VaultAssist's 79 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control VaultAssist

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

Deny destructive operations

{
  "batch_delete_gmail_emails": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "find_and_replace_doc": {
    "limits": [
      {
        "counter": "find_and_replace_doc_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "about": {
    "limits": [
      {
        "counter": "about_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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.

FAQ

Questions about VaultAssist

Can an AI agent delete data through the VaultAssist MCP server? +

Yes. The VaultAssist server exposes 10 destructive tools including batch_delete_gmail_emails, clear_completed_tasks, delete_event. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through VaultAssist? +

The VaultAssist server has 33 write tools including find_and_replace_doc, get_or_create_gmail_label, batch_modify_gmail_emails. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach VaultAssist.

How many tools does the VaultAssist MCP server expose? +

79 tools across 3 categories: Destructive, Read, Write. 34 are read-only. 45 can modify, create, or delete data.

How do I enforce a policy on VaultAssist? +

Register the VaultAssist MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every VaultAssist tool call.

Deterministic rules across all 79 VaultAssist tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
