AI agents call analyze_fortune to retrieve information from Ziwei without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs astrological fortune analysis and prediction by interpreting Ziwei Doushu charts across different temporal dimensions. It retrieves and analyzes existing astrological data to generate predictions and interpretations. No side effects, data modifications, code execution, or financial transactions occur.
From the tool's definition Tool name 'analyze_fortune' and description '分析运势，包括大运、流年、流月等时间维度的运势预测' (analyze fortune, including predictions across time dimensions like major cycles, yearly, and monthly) indicate data retrieval and analysis only.
Documented attack patterns abuse exactly the kind of access analyze_fortune gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ziwei, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_fortune:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_fortune": {}
}
}analyze_fortune is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

分析运势，包括大运、流年、流月等时间维度的运势预测. It is categorised as a Read tool in the Ziwei MCP Server, which means it retrieves data without modifying state.
Register the Ziwei MCP server in PolicyLayer and add a rule for analyze_fortune: 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 Ziwei. Nothing to install.
analyze_fortune 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 analyze_fortune 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 analyze_fortune. 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.
analyze_fortune is provided by the Ziwei MCP server (siwuxue/ziwei-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ziwei, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
