Parameters from the server's own tool schema.
This tool exports/reads contract data from an ERP system into an Excel file. It retrieves existing records without modifying them. The medium severity reflects that it accesses potentially sensitive business contract data that could be misused if exported inappropriately, but it performs no write or destructive operations.
From the tool's definition 导出跟单合同Excel文件 (export after-sales contract Excel file from ERP system)

从ERP系统导出跟单合同Excel文件。必须先调用 brand_select 获取 brandId，再调用 branch_select 获取 branchId 和 cityCode。确认城市公司（必填，支持多选）、确认交单时间范围（选填，不指定则默认本月含今天；单次最长365天，超出时提示用户缩短范围或分批导出）。状态（选填，单选，可选值: 在办单/完结单/已撤单/已交单/未交单，不传则不筛选）。. It is categorised as a Read tool in the Yjzf MCP Server, which means it retrieves data without modifying state.
after_sales_contract accepts 7 parameters: brandId, branchId, cityCode, branchName, submitEndTm, submitStartTm, contractStatus. Required: brandId, branchId, cityCode, branchName. 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 after_sales_contract: 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.
after_sales_contract 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 after_sales_contract 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 after_sales_contract. 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.
after_sales_contract 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.
after_sales_contract is one line of Yjzf's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
