What place_id does on Baidu Map
AI agents call place_id 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 place_id is rated Low
Given the Baidu Map server context and sibling tools that are all read/query operations, 'place_id' most likely retrieves or looks up a place ID. The description 'string' is uninformative, which lowers confidence. No evidence of write, execute, destructive, or financial behavior.
From the tool's definition Tool name is 'place_id' and description is merely 'string' — uninformative. Based on sibling tools (address, business, city, area) and the Baidu Map API context, this likely retrieves a place identifier.
Attacks that exploit this kind of access
The rule that runs place_id 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 place_id, this is the rule to start with:
place_id 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 place_id call is checked against it from then on.
Questions about place_id
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 place_id: 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.
place_id 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 place_id 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 place_id. 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.
place_id 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.
