AI agents call input_tips 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.
Based on naming convention and context within a map/navigation API (Amap), 'input_tips' likely retrieves search suggestions or autocomplete data. This is a read-only operation with no state modification or side effects. Severity is low as it only returns informational data. Confidence is moderate (0.6) due to missing description.

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 input_tips:
{
"version": "1",
"default": "deny",
"tools": {
"input_tips": {}
}
}input_tips is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

input_tips. 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 input_tips: 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.
input_tips 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 input_tips 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 input_tips. 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.
input_tips 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.
