WHAT IT DOES

What rbac_list_assignments does on Enhanced Knowledge Graph Memory Server

AI agents call rbac_list_assignments to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why rbac_list_assignments is rated Low

Even though rbac_list_assignments 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 rbac_list_assignments safely

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

rbac_list_assignments Allowed

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

  "tools": {
    "rbac_list_assignments": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every rbac_list_assignments call is checked against it from then on.
