Permanently delete an entry from your second brain by ID. Only call when the user explicitly asks to delete something. Confirm the entry ID using recall or list_recent first. This action cannot be undone.
AI agents call forget to permanently remove resources in Second Brain Cloudflare — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool deletes data from persistent storage without the ability to recover it. While the severity is not critical (the blast radius is limited to a single user's notes rather than infrastructure or financial systems), the irreversible nature of deletion places it in the Destructive category, which ranks above Execute and Write.
From the tool's definition "Permanently delete an entry" and "This action cannot be undone" indicate irreversible deletion of data.
Documented attack patterns abuse exactly the kind of access forget gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Second Brain Cloudflare, and nothing reaches the server without passing your rules. This is the rule we recommend for forget:
{
"version": "1",
"default": "deny",
"hide": [
"forget"
]
}forget disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Permanently delete an entry from your second brain by ID. Only call when the user explicitly asks to delete something. Confirm the entry ID using recall or list_recent first. This action cannot be undone. It is categorised as a Destructive tool in the Second Brain Cloudflare MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Second Brain Cloudflare MCP server in PolicyLayer and add a rule for forget: 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 Second Brain Cloudflare. Nothing to install.
forget 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 forget 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 forget. 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.
forget is provided by the Second Brain Cloudflare MCP server (rahilp/second-brain-cloudflare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
