What street_number does on Baidu Map
AI agents call street_number 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 street_number is rated Low
Based on the tool name and context (Baidu Map API server with sibling tools like adcode, address, addressComponent, city, cityCode), this tool likely retrieves or parses street number information from an address. This is a read-only data lookup. Confidence is reduced because the description is empty/uninformative ('string'), so the classification is based primarily on naming context.
From the tool's definition Tool name 'street_number' suggests retrieval of address/location data; description is uninformative ('string')
Attacks that exploit this kind of access
The rule that runs street_number 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 street_number, this is the rule to start with:
street_number 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 street_number call is checked against it from then on.

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 street_number: 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.
street_number 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 street_number 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 street_number. 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.
street_number 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.
