AI agents call delete_entities to permanently remove resources in PlayCanvas Editor MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting entities in a game/3D editor is an irreversible operation that removes game objects and cannot be undone by the tool itself (undo is typically a separate editor feature, not part of this tool's contract). This represents permanent loss of content within a project. While scoped to non-root entities, the blast radius remains significant as an agent could delete many critical scene components.
From the tool's definition Tool name is 'delete_entities' with description 'Delete entities (not root)'. The verb 'delete' combined with entity removal action constitutes irreversible data destruction in a 3D scene.

Documented attack patterns abuse exactly the kind of access delete_entities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PlayCanvas Editor MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_entities:
{
"version": "1",
"default": "deny",
"hide": [
"delete_entities"
]
}delete_entities disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete entities (not root). It is categorised as a Destructive tool in the PlayCanvas Editor MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the PlayCanvas Editor MCP Server MCP server in PolicyLayer and add a rule for delete_entities: 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 PlayCanvas Editor MCP Server. Nothing to install.
delete_entities 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 delete_entities 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 delete_entities. 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.
delete_entities is provided by the PlayCanvas Editor MCP Server MCP server (playcanvas/editor-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
