WHAT IT DOES

What util_ratio does on Delx MCP Server

AI agents call util_ratio to retrieve information from Delx MCP Server 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
`a`	integer	Yes	Input field: a.
`b`	integer	Yes	Input field: b.

Parameters from the server's own tool schema.

RISK

Why util_ratio is rated Low

Even though util_ratio only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs util_ratio safely

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

util_ratio Allowed

util_ratio 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": {
    "util_ratio": {}
  }
}

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

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