AI agents call utility_clear_sector to permanently remove resources in TdxQuant MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool clears (empties) custom sector data. '清空' in Chinese means to completely empty/wipe out, which is an irreversible destructive operation. An AI agent misusing this could permanently delete all user-defined custom sector configurations, which cannot be undone. This falls squarely in the Destructive category.
From the tool's definition 清空自定义板块 — '清空' means 'clear/empty', indicating irreversible deletion of all custom sector data
Documented attack patterns abuse exactly the kind of access utility_clear_sector gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and TdxQuant MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for utility_clear_sector:
{
"version": "1",
"default": "deny",
"hide": [
"utility_clear_sector"
]
}utility_clear_sector disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Register the TdxQuant MCP Server MCP server in PolicyLayer and add a rule for utility_clear_sector: 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 TdxQuant MCP Server. Nothing to install.
utility_clear_sector 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 utility_clear_sector 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 utility_clear_sector. 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.
utility_clear_sector is provided by the TdxQuant MCP Server MCP server (lingfan/tdxquant-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from TdxQuant MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
