AI agents call forget_memory to permanently remove resources in SLayer — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The name 'forget_memory' strongly implies removing or erasing stored memory entries, which is typically an irreversible destructive operation. However, the empty description significantly lowers confidence. Given sibling tools include 'delete_datasource' and 'delete_model' (explicitly destructive), 'forget_memory' likely follows the same destructive pattern for memory-related data.
From the tool's definition Tool name 'forget_memory' suggests irreversible deletion of stored memory/state; description is empty providing no additional context.
Documented attack patterns abuse exactly the kind of access forget_memory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SLayer, and nothing reaches the server without passing your rules. This is the rule we recommend for forget_memory:
{
"version": "1",
"default": "deny",
"hide": [
"forget_memory"
]
}forget_memory disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

forget_memory. It is categorised as a Destructive tool in the SLayer MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the SLayer MCP server in PolicyLayer and add a rule for forget_memory: 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 SLayer. Nothing to install.
forget_memory 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_memory 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_memory. 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_memory is provided by the SLayer MCP server (motleyai/slayer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SLayer, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
