AI agents call getBaziDetail to retrieve information from Bazi MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns Bazi calculation results based on input parameters (solar or lunar datetime and gender). It is a read-only operation that retrieves data without side effects, modifying data, executing code, deleting data, or affecting financial systems. The low severity reflects that misuse would only result in retrieval of fortune-telling calculations with no real-world impact.
From the tool's definition Tool name is 'getBaziDetail' and description states it retrieves (获取) Bazi information based on time and gender inputs. No modification, deletion, or execution of external operations is performed.

Register the Bazi MCP server in PolicyLayer and add a rule for getBaziDetail: 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 Bazi MCP. Nothing to install.
getBaziDetail 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 getBaziDetail 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 getBaziDetail. 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.
getBaziDetail is provided by the Bazi MCP server (shuangzixing1976/bazi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
