Why random_phone is rated Low
This tool produces synthetic data (random phone numbers) deterministically without side effects, system queries, or external state changes. It is a data generation utility that falls under the Read category as a data-producing function with no reversible or irreversible modifications to real systems. Severity is low because misuse would only generate harmless synthetic values with no operational impact.
From the tool's definition Tool generates random phone numbers using Faker library; described as 'Generate random phone number(s)' with no indication of data retrieval from actual systems, modification, execution, or destructive operations.
Attacks that exploit this kind of access
The rule that runs random_phone safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For random_phone, this is the rule to start with:
random_phone is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every random_phone call is checked against it from then on.
