通过快递公司编码、收寄件地址、下单时间、历史物流轨迹信息来预估快递送达的时间；用于在途快递的到达时间预估
AI agents call estimate_time_with_logistic to retrieve information from Kuaidi100 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes existing logistics data to provide time estimations. It queries package tracking information and history to predict delivery arrival times, which is a read-only operation with no impact on actual system state or data modification. The low severity reflects minimal risk if misused—inaccurate time estimates cause inconvenience but no irreversible harm or financial loss.
From the tool's definition Tool description states it estimates delivery time based on logistics company code, addresses, order time, and historical logistics information ("预估快递送达的时间").
Documented attack patterns abuse exactly the kind of access estimate_time_with_logistic gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kuaidi100 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for estimate_time_with_logistic:
{
"version": "1",
"default": "deny",
"tools": {
"estimate_time_with_logistic": {}
}
}estimate_time_with_logistic is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

通过快递公司编码、收寄件地址、下单时间、历史物流轨迹信息来预估快递送达的时间；用于在途快递的到达时间预估. It is categorised as a Read tool in the Kuaidi100 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kuaidi100 MCP Server MCP server in PolicyLayer and add a rule for estimate_time_with_logistic: 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 Kuaidi100 MCP Server. Nothing to install.
estimate_time_with_logistic is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the estimate_time_with_logistic 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 estimate_time_with_logistic. 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.
estimate_time_with_logistic is provided by the Kuaidi100 MCP Server MCP server (kuaidi100-api/kuaidi100-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kuaidi100 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
