WHAT IT DOES

What roman does on Gateway

AI agents call roman to retrieve information from Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`mode`	string	—	Direction
`roman`	string	—	Roman numeral string (to_int)
`number`	integer	—	Integer 1..3999 (to_roman)

Parameters from the server's own tool schema.

RISK

Why roman is rated Low

This is a stateless mathematical conversion utility. It retrieves or computes a representation of input data without creating, modifying, deleting, or executing any operations. The conversion is deterministic and reversible. Misuse by an AI agent (e.g., converting arbitrary numbers) poses no security risk—blast radius is zero.

From the tool's definition Tool description states 'Convert an integer (1..3999) to Roman numerals or back' — a pure conversion/transformation function with no side effects, no data modification, no external operations triggered.

RECOMMENDED RULE

The rule that runs roman safely

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

roman Allowed

roman is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "roman": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Gateway, apply this rule, and every roman call is checked against it from then on.
