WHAT IT DOES

What roll_dice does on VaultAssist

AI agents call roll_dice as a supporting operation in VaultAssist workflows.

RISK

Why roll_dice is rated Low

Rolling a die is a local computation that generates a random number. It does not read, write, execute, destroy, or involve financial operations. It is a self-contained utility function with no meaningful blast radius.

From the tool's definition 'Roll an N-sided die' - this is a pure random number generation utility with no side effects, data access, or external operations

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs roll_dice safely

PolicyLayer is an MCP gateway: it sits between your AI agents and VaultAssist, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For roll_dice, this is the rule to start with:

roll_dice Rate-limited

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