AI agents call role_pc_list 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.
This tool fetches configuration data (role type lists) needed by other tools. It performs a read-only query operation that retrieves reference information without creating, modifying, deleting, executing code, or moving money. The blast radius of misuse is minimal—an attacker could only see what role types exist in the system. This is characteristic of a Read category tool.
From the tool's definition Tool name 'role_pc_list' and description indicate it 'retrieves/gets a list of role types (角色类型列表)' for use in subsequent exports. The description explicitly states it is called 'before' another export tool to obtain valid roleType values.

获取新房开发商回款导出的角色类型列表。调用新房开发商回款导出（new_house_developer_repayment_export）前，必须先调用此工具获取有效的 roleType 值，再传入导出工具的 roleType 参数。. It is categorised as a Read tool in the Yjzf MCP Server, which means it retrieves data without modifying state.
role_pc_list accepts 2 parameters: brandId, branchId. Required: brandId, branchId. 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 role_pc_list: 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.
role_pc_list 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 role_pc_list 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 role_pc_list. 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.
role_pc_list 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.
