Convert address to geographic coordinates using Amap API.
AI agents call geocode to retrieve information from XiaozhiMCP-MapNAVI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries geographic data (address-to-coordinate conversion) and returns results without side effects. It matches the Read category definition: retrieves or queries data with no side effects. Severity is low because misuse (e.g., geocoding an arbitrary address) causes no harm—it simply returns public geographic information.
From the tool's definition Tool description states 'Convert address to geographic coordinates' — a pure data retrieval operation with no modification, deletion, or execution of external commands. The Amap geocoding API is a standard read-only lookup service.
Documented attack patterns abuse exactly the kind of access geocode gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and XiaozhiMCP-MapNAVI, and nothing reaches the server without passing your rules. This is the rule we recommend for geocode:
{
"version": "1",
"default": "deny",
"tools": {
"geocode": {}
}
}geocode is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Convert address to geographic coordinates using Amap API. It is categorised as a Read tool in the XiaozhiMCP-MapNAVI MCP Server, which means it retrieves data without modifying state.
Register the XiaozhiMCP-MapNAVI MCP server in PolicyLayer and add a rule for geocode: 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 XiaozhiMCP-MapNAVI. Nothing to install.
geocode 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 geocode 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 geocode. 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.
geocode is provided by the XiaozhiMCP-MapNAVI MCP server (rickeylaiii/xiaoai_mapmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from XiaozhiMCP-MapNAVI, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
