get_user

THE RISK

Low Risk

Why get_user needs a policy

This tool retrieves user information from the HUDU platform without side effects. It is a read-only query operation. Severity is medium rather than low because user details may include sensitive information (contact details, access roles, credentials metadata) that could be valuable if disclosed to an unauthorized agent, though the tool itself performs no dangerous actions.

From the tool's definition Tool name is 'get_user' and description states it 'Get detailed information about a specific user' — a retrieval operation with no modification or destructive capability.

POLICY

How to control get_user

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

policy.json

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

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

Create a free account and register HUDU MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
