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

  "jsonrpc": "2.0",

## Why custom_create_landing_page is rated Medium

This tool creates new landing page assets in Marketo, which is a reversible write operation. While landing pages can be deleted, the primary action is creation/modification of data. Severity is high because an AI agent could create numerous landing pages, disrupt marketing campaigns, or pollute the asset library, though financial impact is indirect.

From the tool's own definition: "Tool name 'custom_create_landing_page' indicates creation of a landing page asset. Description states it 'Calls the Marketo REST API directly' for asset management."

## Use case

AI agents use custom_create_landing_page to create or update resources in Marketo MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Marketo MCP Server environment.
