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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "get_subscription",
    "arguments": {}
  }

```

## Why get_subscription is rated Low

The tool queries existing subscription metadata from a billing system without creating charges, modifying billing state, or triggering payment flows. While it accesses billing-related information, the act is purely informational retrieval. Severity is low because exposure would reveal billing details but not enable unauthorized transactions or data destruction.

From the tool's own definition: "Tool retrieves subscription details: 'plan, active flag, period start/end, cancel-at-period-end flag, external Paddle subscription id, and whether a payment method is on file'."

## Use case

AI agents call get_subscription to retrieve information from EchoRelay 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 EchoRelay:

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