While it accesses marketing automation data that could be sensitive (email templates, configurations), the read-only nature and lack of side effects places it in the Read category. From the tool's own definition: "Tool description states it 'Calls the Marketo REST API directly' to get email variables. The verb 'get' and the function of retrieving variables indicates a read operation with no modification or execution capability." ## Use case AI agents call custom_get_email_variables 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**.
