WHAT IT DOES

What policy_list does on Amazon Location Service MCP Server

AI agents call policy_list to retrieve information from Amazon Location Service MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why policy_list needs a policy

Policy listing is a read operation that retrieves policy data without side effects. Severity is medium rather than low because policy information disclosure could inform further attacks, but it has no direct destructive or financial impact. Confidence is lowered from 0.85 to 0.75 due to empty description, which prevents confirmation of the exact scope and parameters.

From the tool's definition Tool name is 'policy_list' which semantically suggests listing/querying policies without modification. The tool appears to be part of AWS Location Service MCP server.

Documented attack patterns abuse exactly the kind of access policy_list gives an agent:

POLICY

How to control policy_list

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Location Service MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for policy_list:

policy.json

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

policy_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
