WHAT IT DOES

What sign_set_text does on Uefn

AI agents use sign_set_text to create or update resources in Uefn, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Uefn environment.

RISK

Why sign_set_text is rated Medium

This tool creates or modifies text data on a sign asset, which is a reversible write operation typical of content creation in a game editor. No deletion, execution of arbitrary code, or financial impact. Severity is medium because modifying game assets could affect intended creative content, but changes are easily undoable via undo/revert in the editor.

From the tool's definition Tool name 'sign_set_text' indicates modification of text content on a sign object in UEFN. The 'set' verb and context within a Fortnite editor environment suggests updating existing sign data.

RECOMMENDED RULE

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

sign_set_text Rate-limited

sign_set_text stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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