```json
{
  "jsonrpc": "2.0",

## Why marketo_get_channels is rated Low

The tool performs a read-only operation that retrieves channel information from the Marketo instance. It has no capacity to modify, create, or delete data. While it provides visibility into channel progression statuses, unauthorized access would have minimal immediate impact. The severity is low because reading metadata about channels does not directly expose sensitive personal data or enable unauthorized actions.

From the tool's own definition: "Tool description states 'List all program channels' with no modification, creation, or deletion involved. This is a query operation that retrieves existing data about channels without side effects."

## Use case

AI agents call marketo_get_channels 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": {
    "marketo_get_channels": {}
  }
}
```
