WHAT IT DOES

What rename_blueprint_function does on Unreal-MCP

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

RISK

Why rename_blueprint_function is rated Medium

Renaming a Blueprint function is a write operation—it creates a modified state in the project by changing metadata. It is reversible (can be undone or renamed again), so it does not qualify as Destructive. The impact is scoped to a single function's identifier within the Blueprint system, affecting only that asset's structure.

From the tool's definition Tool directly modifies a Blueprint function's name via 'rename_blueprint_function'. The description explicitly states it performs a rename operation, which is a reversible structural change to project assets.

RECOMMENDED RULE

The rule that runs rename_blueprint_function safely

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

rename_blueprint_function Rate-limited

rename_blueprint_function 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

What risk level is rename_blueprint_function? +

rename_blueprint_function is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit rename_blueprint_function? +

Yes. Add a rate_limit block to the rename_blueprint_function rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block rename_blueprint_function completely? +
