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

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

## Why decrypt_backup is rated Low

The 'decrypt' verb typically indicates reading/accessing encrypted data. However, confidence is reduced to 0.45 because the description is empty and uninformative, leaving interpretation vulnerable to alternative readings (e.g., decryption could enable subsequent destructive actions).

From the tool's own definition: "Tool named 'decrypt_backup' with empty description. The name suggests it decrypts (unlocks/reads) backup data rather than modifying or deleting it."

## Use case

AI agents call decrypt_backup to retrieve information from Metis Public Health 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 Metis Public Health:

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