WHAT IT DOES

What get_user_policy does on AWS

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

RISK

Why get_user_policy is rated Low

The 'get' prefix strongly suggests a read operation that retrieves user policy data without modification. In AWS IAM context, retrieving policies is a read operation with no side effects.

From the tool's definition Tool name 'get_user_policy' indicates retrieval of policy information. No description provided, but sibling tools like 'attach_user_policy' and 'attach_group_policy' suggest this server manages AWS IAM operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_user_policy safely

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

get_user_policy Allowed

get_user_policy 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": {
    "get_user_policy": {}
  }
}

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

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