What rename_niagara_node_pin does on Unreal-MCP
AI agents use rename_niagara_node_pin 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.
Why rename_niagara_node_pin is rated Medium
Renaming a node pin is a reversible modification of asset metadata (the pin's name/label) within the Unreal Engine editor. This is a Write operation because it creates or modifies data reversibly. The severity is medium because incorrect renames could break node connections or create workflow confusion, but the effect is limited to a single pin and is easily undone via undo operations typical in modern editors.
From the tool's definition Tool explicitly performs 'Rename' action on a pin within a Niagara node in a scratch pad graph, which modifies metadata of an existing asset without deleting or executing arbitrary code.
Attacks that exploit this kind of access
The rule that runs rename_niagara_node_pin 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_niagara_node_pin, this is the rule to start with:
rename_niagara_node_pin 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 Unreal-MCP, apply this rule, and every rename_niagara_node_pin call is checked against it from then on.
Questions about rename_niagara_node_pin
Rename a dynamic pin on any node in a scratch pad graph. It is categorised as a Write tool in the Unreal-MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Unreal MCP server in PolicyLayer and add a rule for rename_niagara_node_pin: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Unreal-MCP. Nothing to install.
rename_niagara_node_pin is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the rename_niagara_node_pin 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.
Set action: deny in the PolicyLayer policy for rename_niagara_node_pin. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
rename_niagara_node_pin is provided by the Unreal MCP server (aadeshrao123/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
