Parameters from the server's own tool schema.
This is a read-only data retrieval and export tool. It queries an ERP system for contract information and exports results to Excel, with filtering by city, date range, contract type, and status. No write, delete, or execute operations are performed on the underlying data. The export action only extracts existing data; it does not modify the ERP system.
From the tool's definition Tool description states it "查询/导出电子合同明细Excel文件" (queries/exports electronic contract details to Excel file). Core actions are: get_contract_types (retrieves options), get_contract_states (retrieves options), query (previews data), and export (executes export).

It is categorised as a Read tool in the Yjzf MCP Server, which means it retrieves data without modifying state.
electronic_contract accepts 11 parameters: action, pageNo, brandId, branchId, cityCode, pageSize, typeList, stateList, branchName, createTmEnd, createTmBegin. Required: action, 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 electronic_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.
electronic_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 electronic_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 electronic_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.
electronic_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.
