AI agents call delete_entity to permanently remove resources in Novyx — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data from the knowledge graph without the ability to restore it. While the server provides audit trails and approval workflows (suggesting governance controls), the underlying operation itself is destructive. An AI agent misusing this tool could irreversibly erase important entity data.
From the tool's definition Tool name 'delete_entity' combined with description 'Delete a knowledge graph entity and all its triples' indicates irreversible deletion of data. The use of 'Delete' and 'all its triples' shows this operation cannot be undone.
Documented attack patterns abuse exactly the kind of access delete_entity gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Novyx, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_entity:
{
"version": "1",
"default": "deny",
"hide": [
"delete_entity"
]
}delete_entity disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a knowledge graph entity and all its triples. It is categorised as a Destructive tool in the Novyx MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Novyx MCP server in PolicyLayer and add a rule for delete_entity: 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 Novyx. Nothing to install.
delete_entity 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_entity 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_entity. 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_entity is provided by the Novyx MCP server (novyxlabs/novyx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
