THE RISK

Low Risk

Why generate_ulid needs a policy

This tool generates a ULID locally — a time-sortable unique identifier. It performs a pure computation with no side effects: no data is read from external sources, no data is written or modified, no code is executed, nothing is deleted, and no financial transactions occur. It simply produces a random/time-based string value.

From the tool's definition Generate Universally Unique Lexicographically Sortable Identifier (ULID). Example: creates time-sortable unique IDs

POLICY

How to control generate_ulid

PolicyLayer is an MCP gateway — it sits between your AI agents and IT Tools MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_ulid:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_ulid": {
      "limits": [
        {
          "counter": "generate_ulid_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_ulid gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register IT Tools MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
