从双端队列模式ListMemory的前端或后端弹出元素，遵循先进先出或后进先出原则。
AI agents use popDequeElement to create or update resources in ThinkMem — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ThinkMem environment.
This tool modifies list memory by removing elements from either end of a deque structure. While 'pop' operations typically return the removed element (suggesting reversibility in principle), the primary effect is to mutate the memory state.
From the tool's definition popDequeElement removes/modifies elements from a deque data structure ('从双端队列模式ListMemory的前端或后端弹出元素'), which constitutes data modification. The operation is reversible if the removed element is preserved elsewhere, but modifies the underlying memory structure.
Documented attack patterns abuse exactly the kind of access popDequeElement 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 popDequeElement:
{
"version": "1",
"default": "deny",
"tools": {
"popDequeElement": {
"limits": [
{
"counter": "popdequeelement_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}popDequeElement stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Register the ThinkMem MCP server in PolicyLayer and add a rule for popDequeElement: 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.
popDequeElement is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the popDequeElement 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 popDequeElement. 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.
popDequeElement 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.
