What city does on Baidu Map
AI agents call city 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 city is rated Low
Given the server context (Baidu Map API) and the tool name 'city', this likely retrieves city-related geographic information. Read is the most appropriate category for a lookup/query operation. Confidence is low due to the uninformative description.
From the tool's definition Tool name is 'city'; description is uninformative ('string') — no further detail provided.
Attacks that exploit this kind of access
The rule that runs city 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 city, this is the rule to start with:
city 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 city call is checked against it from then on.
Questions about city
string. 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 city: 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.
city 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 city 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 city. 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.
city 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.
