## Why mmp_list is rated Low

This tool retrieves and displays information about available packages without modifying, deleting, or executing anything. It is purely informational, matching the Read category profile (list, fetch, search). The blast radius of misuse is minimal—an agent listing packages cannot cause data loss or financial harm.

From the tool's own definition: "Tool name 'mmp_list' and description 'List available MMP packages' indicate a query/enumeration operation with no side effects."

## Use case

AI agents call mmp_list to retrieve information from Pypi:dense Knowledge 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 Pypi:dense Knowledge:

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