距离测量。计算多个起点到一个终点的驾车距离和时间。用于比较不同出发点的可达性。
AI agents call amap_distance to retrieve information from Amap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and calculates geographic distance and transit time information based on provided coordinates or locations. It performs no mutations, has no side effects, triggers no external operations with unpredictable consequences, and involves no financial transactions. It is a straightforward read operation on map data.
From the tool's definition Tool name 'amap_distance' and description '距离测量。计算多个起点到一个终点的驾车距离和时间。用于比较不同出发点的可达性' (distance measurement; calculate driving distance and time from multiple starting points to one endpoint; used to compare reachability from different departure points).

距离测量。计算多个起点到一个终点的驾车距离和时间。用于比较不同出发点的可达性。. It is categorised as a Read tool in the Amap MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amap MCP Server MCP server in PolicyLayer and add a rule for amap_distance: 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 Amap MCP Server. Nothing to install.
amap_distance 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 amap_distance 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 amap_distance. 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.
amap_distance is provided by the Amap MCP Server MCP server (zengzeruidd-a11y/amap-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
