合婚分析，分析两人的紫微斗数命盘匹配度
AI agents call analyze_compatibility 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 analysis and comparison of astrological charts to assess compatibility between two individuals. It retrieves and queries existing astrological data to generate an interpretation, with no side effects, data modification, code execution, or irreversible actions. This is a pure read operation typical of divination/astrology services.
From the tool's definition Tool description: '合婚分析，分析两人的紫微斗数命盘匹配度' (compatibility analysis, analyzes the matching degree of two people's Ziwei Doushu charts). The tool 'analyzes' and 'interprets' astrological data without modifying, deleting, or executing external operations.
Documented attack patterns abuse exactly the kind of access analyze_compatibility 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_compatibility:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_compatibility": {}
}
}analyze_compatibility is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
合婚分析，分析两人的紫微斗数命盘匹配度. 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_compatibility: 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_compatibility 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_compatibility 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_compatibility. 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_compatibility 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.
