WHAT IT DOES

What custom_get_lead_partitions does on Marketo MCP Server

AI agents call custom_get_lead_partitions 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.

RISK

Why custom_get_lead_partitions is rated Low

Lead partition retrieval is a read-only operation that queries existing data structures without side effects. The context of the Marketo server (managing leads, campaigns, etc.) and the 'get_' naming convention confirm this is a query operation. The [CUSTOM] notation indicates a direct API wrapper, but the operation itself remains read-only data retrieval with minimal blast radius if misused by an AI agent.

From the tool's definition Tool name includes 'get_' prefix indicating data retrieval. Description states it 'Calls the Marketo REST API directly' to query lead partitions, which are configuration/organizational objects.

Attacks that exploit this kind of access
