What location does on Baidu Map
AI agents call location to retrieve information from Baidu Map without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why location is rated Low
The tool appears to deal with geographic location data (longitude and latitude), which is a read/query operation typical of map APIs. However, the description is extremely sparse and uninformative, providing only a data structure rather than a clear action description.
From the tool's definition Tool name 'location' and description '{ lng: number, lat: number }' suggest it retrieves or returns geographic coordinates (longitude/latitude).
Attacks that exploit this kind of access
The rule that runs location safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Baidu Map, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For location, this is the rule to start with:
location is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Baidu Map, apply this rule, and every location call is checked against it from then on.
Questions about location
{ lng: number, lat: number }. It is categorised as a Read tool in the Baidu Map MCP Server, which means it retrieves data without modifying state.
Register the Baidu Map MCP server in PolicyLayer and add a rule for location: 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 Baidu Map. Nothing to install.
location 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 location 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 location. 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.
location is provided by the Baidu Map MCP server (@baidumap/mcp-server-baidu-map). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
