WHAT IT DOES

What list_assets does on Uefn

AI agents call list_assets 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 list_assets is rated Low

The 'list' prefix is a strong signal for data retrieval with no side effects. Given the context of a UEFN editor bridge, this tool likely queries available assets without modifying, executing, or deleting anything. The empty description lowers confidence slightly, but the naming pattern and sibling tools provide sufficient evidence.

From the tool's definition Tool name 'list_assets' indicates asset enumeration/query functionality. Description is empty, but the naming convention aligns with other Read-category tools on this server (e.g., 'audio_list').

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_assets 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 list_assets, this is the rule to start with:

list_assets Allowed

list_assets 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": {
    "list_assets": {}
  }
}

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 list_assets call is checked against it from then on.
