WHAT IT DOES

What search_assets does on Unreal

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

Parameter	Type	Required	Description
`query`	string	Yes	Search query (asset name substring)
`class_filter`	string	—	Filter by asset class

Parameters from the server's own tool schema.

RISK

Why search_assets is rated Low

This tool retrieves asset metadata based on search criteria. It performs a read-only operation that queries existing assets without creating, modifying, deleting, or executing any changes to the Unreal Engine project or assets.

From the tool's definition Tool name 'search_assets' and description 'Search for assets by name, class, or tag' indicate a query/retrieval operation with no modifications or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_assets safely

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

search_assets Allowed

search_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": {
    "search_assets": {}
  }
}

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

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