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

```json

## Why list_secret_patterns is rated Low

This tool performs a retrieval operation on a static or semi-static collection of secret detection patterns. It does not modify, execute external commands, delete, or affect financial systems. The read of security pattern metadata poses minimal risk even if disclosed, as these are detection rules, not secrets themselves.

From the tool's own definition: "Tool name and description indicate it 'List[s] built-in secret detection patterns (denylist)' — a read-only query operation that retrieves and displays existing pattern data with no side effects."

## Use case

AI agents call list_secret_patterns to retrieve information from Todos 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 Todos:

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