## Why serac_list is rated Low

This tool retrieves and enumerates stored keys, which is a classic Read operation with no side effects. It performs a simple listing/query operation similar to 'ls' or 'list' commands. The prefix filter is a retrieval parameter, not a modification. No data is created, modified, deleted, or financial operations are involved.

From the tool's own definition: "Tool name 'serac_list' and description 'List keys in a namespace with optional prefix filter' indicate a read-only operation that queries existing data without modification."

## Use case

AI agents call serac_list to retrieve information from Serac 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 Serac:

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