WHAT IT DOES

What sign_list does on Uefn

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

RISK

Why sign_list is rated Low

This tool retrieves or queries data about sign actors in the level without creating, modifying, deleting, or executing anything. It is a straightforward list operation that fits the Read category definition. The low severity reflects that listing existing actors poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'sign_list' and description 'List all text/sign actors in the level' indicate a query/retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs sign_list safely

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

sign_list Allowed

sign_list 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": {
    "sign_list": {}
  }
}

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

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