WHAT IT DOES

What access_list_users does on UniFi Access MCP

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

RISK

Why access_list_users is rated Low

The tool's name 'list_users' performs a retrieval operation that queries and returns user information without modifying, deleting, or executing actions. Given the UniFi Access context where users are credentials/access identities, this is consistent with Read category tools that retrieve system state.

From the tool's definition Tool name 'access_list_users' indicates a listing/querying operation with no modification verbs. The pattern matches sibling tools like 'access_get_*' which are read operations. Tool description is empty, limiting confidence slightly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs access_list_users safely

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

access_list_users Allowed

access_list_users 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": {
    "access_list_users": {}
  }
}

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

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