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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why hotel_details is rated Low

This tool queries and returns hotel metadata in read-only fashion. It fetches information about a specific hotel (gallery images, facilities, policies, room details) but does not modify data, execute external operations, delete records, or commit financial transactions. The credit cost is a usage meter, not a financial transaction. Classification as Read is appropriate.

From the tool's own definition: "Tool name 'hotel_details' and description 'Rich metadata (gallery, facilities, policies, per-room details) for a single hotel' indicate retrieval of hotel information with no modification or side effects."

## Use case

AI agents call hotel_details to retrieve information from Jinko MCP 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 Jinko MCP:

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