AI agents call delete_product to permanently remove resources in AI Cognitive Nexus — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes product records and associated knowledge bases without the ability to undo the action. While the blast radius is bounded to product data rather than system-wide resources, the irreversible nature of deletion and the potential loss of knowledge base content—which may be important for multi-agent workflows on this system—classifies this as Destructive.
From the tool's definition Tool name is 'delete_product' and description states '删除一个指定的产品记录及其知识库' (delete a specified product record and its knowledge base). The use of 'delete' (删除) indicates irreversible removal of data.
Documented attack patterns abuse exactly the kind of access delete_product gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AI Cognitive Nexus, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_product:
{
"version": "1",
"default": "deny",
"hide": [
"delete_product"
]
}delete_product disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

删除一个指定的产品记录及其知识库。. It is categorised as a Destructive tool in the AI Cognitive Nexus MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the AI Cognitive Nexus MCP server in PolicyLayer and add a rule for delete_product: 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 AI Cognitive Nexus. Nothing to install.
delete_product 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_product 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_product. 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_product is provided by the AI Cognitive Nexus MCP server (simonutd/ai-cognitive-nexus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AI Cognitive Nexus, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
