Query program members from Marketo with filtering options.
AI agents call query_program_members to retrieve information from Marketo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries existing program member data from Marketo without creating, modifying, or deleting any records. It has no side effects beyond fetching information. The filtering options are for narrowing the query scope, not for making changes. This is a standard Read category tool with low risk if misused by an AI agent, as it only exposes data that may already be accessible to the user.
From the tool's definition Tool name 'query_program_members' and description 'Query program members from Marketo with filtering options' indicate data retrieval with filtering capabilities. The verb 'query' and lack of any modification language confirm read-only operations.
