## Why get_certificate_authority is rated Low

This tool retrieves certificate authority information, which is a read-only query operation. It does not modify, delete, execute, or move any resources. The blast radius is minimal as it only exposes certificate metadata needed for secure connections. Confidence is high because the verb 'get' and 'retrieve' semantics are unambiguous.

From the tool's own definition: "Tool name 'get_certificate_authority' and description 'Get the certificate authority for a Memorystore for Valkey instance' indicate a retrieval operation with no side effects."

## Use case

AI agents call get_certificate_authority to retrieve information from 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 Mcp:

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