## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "street_number",
    "arguments": {}
  }
}
```

## 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 own definition: "Tool name 'street_number' suggests retrieval of address/location data; description is uninformative ('string')"

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Baidu Map:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "street_number": {}
  }
}
```
