AI agents call deleteRawLines to permanently remove resources in ThinkMem — 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 memory storage without the ability to undo the action. The automatic shifting of subsequent lines indicates a structural modification that cannot be easily recovered.
From the tool's definition Tool name 'deleteRawLines' combined with description stating it 'deletes text content from specified line ranges in RawMemory' with automatic shift of subsequent lines. This is an irreversible deletion operation on stored data.
Documented attack patterns abuse exactly the kind of access deleteRawLines gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ThinkMem, and nothing reaches the server without passing your rules. This is the rule we recommend for deleteRawLines:
{
"version": "1",
"default": "deny",
"hide": [
"deleteRawLines"
]
}deleteRawLines 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RawMemory中指定行范围的文本内容，后续行会自动前移。. It is categorised as a Destructive tool in the ThinkMem MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the ThinkMem MCP server in PolicyLayer and add a rule for deleteRawLines: 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 ThinkMem. Nothing to install.
deleteRawLines 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 deleteRawLines 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 deleteRawLines. 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.
deleteRawLines is provided by the ThinkMem MCP server (rickonono3/thinkmem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ThinkMem, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
