Get tracked GTM components with optional filtering
AI agents call get_gtm_components to retrieve information from Google Tag Manager 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 information about existing GTM components and allows filtering of results. There is no indication of creation, modification, deletion, or execution of external operations. The 'no side effects' characteristic of read operations applies here—the tool simply queries and returns data about GTM configuration state without altering it.
From the tool's definition Tool name 'get_gtm_components' and description 'Get tracked GTM components with optional filtering' indicate a retrieval operation with no side effects. The verb 'Get' and presence of 'optional filtering' are consistent with data query operations.
