WHAT IT DOES

What validate_iin does on Marketplace

AI agents call validate_iin to retrieve information from Marketplace 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
`iin`	string	Yes

Parameters from the server's own tool schema.

RISK

Why validate_iin is rated Low

Even though validate_iin 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs validate_iin safely

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

validate_iin Allowed

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

policy.json

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

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

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