WHAT IT DOES

What roads does on Baidu Map

AI agents call roads 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.

RISK

Why roads is rated Low

This tool fetches an array of nearby roads from the Baidu Map API. It is a read-only data retrieval operation returning geographical road information. No data is created, modified, or deleted. Blast radius is minimal as misuse would only result in unnecessary API calls or exposure of location data.

From the tool's definition 'Array of nearby roads' - retrieves/queries nearby road data, purely informational with no side effects

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs roads 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 roads, this is the rule to start with:

roads Allowed

roads is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "roads": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Baidu Map, apply this rule, and every roads call is checked against it from then on.
