WHAT IT DOES

What lei_lookup does on Marketplace

AI agents call lei_lookup 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
`q`	string	—
`lei`	string	—

Parameters from the server's own tool schema.

RISK

Why lei_lookup is rated Low

Even though lei_lookup 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 lei_lookup 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 lei_lookup, this is the rule to start with:

lei_lookup Allowed

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

  "default": "deny",
  "tools": {
    "lei_lookup": {}
  }
}

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 lei_lookup call is checked against it from then on.
