## Why marketo_get_smart_lists is rated Low

This tool queries and returns information about smart lists in Marketo. It does not create, modify, delete, or execute any operations; it only fetches and lists existing data. The blast radius of misuse is minimal—an agent could see smart list configurations but cannot alter them or trigger external effects. This is a classic Read operation.

From the tool's own definition: "'List smart lists' with 'metadata including filter rules and folder location' — retrieves data without modification or side effects. Pagination parameters (maxReturn, offset) indicate read-only querying."

## Use case

AI agents call marketo_get_smart_lists to retrieve information from Marketo MCP Server 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 Marketo MCP Server:

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