This tool performs a straightforward data retrieval operation—converting a place name into coordinates. It is a read-only query with no capability to modify data, execute code, delete information, or trigger external side effects. The blast radius of misuse is minimal, as worst-case scenarios involve receiving incorrect or unexpected coordinate data, which cannot cause harm to systems or data integrity.

PolicyLayer is an MCP gateway — it sits between your AI agents and Ziwei Astrology MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for geocode_location:
{
"version": "1",
"default": "deny",
"tools": {
"geocode_location": {}
}
}geocode_location is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
