AI agents call cust_trans_export to retrieve information from Yjzf without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
The tool exports/reads customer conversion data from the platform. Despite the broad data access (customer records, transaction data, business opportunity data), it is fundamentally a read/export operation with no stated side effects. The async polling mechanism further confirms it is retrieving pre-existing data. Severity is medium due to the sensitivity of customer and sales pipeline data being exported.

导出平台潜客转化数据。支持按城市公司、第三方平台、商机类型、商机来源、商机状态、分发标记、是否付费、第三方创建时间、首次接收时间、是否带看、是否成交、客户录入时间、签单日期等筛选。使用异步轮询方式等待导出完成。. It is categorised as a Read tool in the Yjzf MCP Server, which means it retrieves data without modifying state.
cust_trans_export accepts 12 parameters: brandId, typeOne, typeTen, branchId, numTwoGe, numTwoLt, signTmGe, signTmLt, typeSeven, branchName, numThreeGe, numThreeLt. Required: brandId, branchId, branchName, numThreeGe, numThreeLt. The full parameter table on this page comes from the server's own tool schema.
Register the Yjzf MCP server in PolicyLayer and add a rule for cust_trans_export: 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 Yjzf. Nothing to install.
cust_trans_export 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 cust_trans_export 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 cust_trans_export. 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.
cust_trans_export is provided by the Yjzf MCP server (@yjzf/mcp-server-yjzf). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
