AI agents call amap_direction_transit 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.
amap_direction_transit retrieves route planning information from the Amap service. It takes input parameters (start point, end point, city) and returns data about transit options. This is fundamentally a read operation—it queries map data and returns recommendations without modifying any state, creating bookings, executing code, or deleting information.
From the tool's definition Tool description indicates it 'returns public transit/metro route plans' (返回公交换乘方案) with information including walking segments, bus lines, metro lines, transfer counts, total time, and fare.

Register the Amap MCP Server MCP server in PolicyLayer and add a rule for amap_direction_transit: 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_direction_transit 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_direction_transit 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_direction_transit. 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_direction_transit 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.
