Remove a node from an existing scene in a Godot project
AI agents call remove_node to permanently remove resources in Godot MCP Unified — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing nodes from a scene is a destructive operation that permanently modifies the scene structure. While Godot's undo/redo system may theoretically allow recovery during an interactive session, an autonomous agent using this tool could delete critical scene nodes that define gameplay logic, UI, or other essential components. The operation is irreversible at the MCP tool level and represents data loss.
From the tool's definition The tool is named 'remove_node' and the description explicitly states it will 'Remove a node from an existing scene'. This operation irreversibly deletes nodes from a Godot scene, which cannot be easily undone programmatically by an agent.
Attacks that exploit this kind of access
Remove a node from an existing scene in a Godot project. It is categorised as a Destructive tool in the Godot MCP Unified MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Godot MCP Unified MCP server in PolicyLayer and add a rule for remove_node: 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 Godot MCP Unified. Nothing to install.
remove_node is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_node 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 remove_node. 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.
remove_node is provided by the Godot MCP Unified MCP server (pierrealexandreguillemin-a11y/godot-mcp-unified). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
