The most dangerous SmartTools tools

Destructive · High remove_duplicates Remove duplicate lines, with optional trim, case-insensitive matching, sorting or keeping only the duplicated lines. Runs on smart-tools.xyz Destructive · High vat_calculator Add VAT to a net amount or remove it from a gross amount. Runs on smart-tools.xyz.

69 of SmartTools's 73 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control SmartTools

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

Deny destructive operations
{
  "remove_duplicates": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

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

Cap read operations
{
  "data_converter": {
    "limits": [
      {
        "counter": "data_converter_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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

FAQ

Questions about SmartTools

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

Yes. The SmartTools server exposes 2 destructive tools including remove_duplicates, vat_calculator. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How many tools does the SmartTools MCP server expose? +

73 tools across 3 categories: Destructive, Execute, Read. 4 are read-only. 69 can modify, create, or delete data.

How do I enforce a policy on SmartTools? +

Register the SmartTools 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 SmartTools tool call.

Deterministic rules across all 73 SmartTools tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
