Get details of a specific annotation in a Google Analytics 4 property.
AI agents call ga4_admin_api_get_annotation to retrieve information from Google Analytics 4 Admin MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves annotation details from a GA4 property. It performs a read-only operation with no capability to modify, delete, or execute actions. The blast radius of misuse is minimal — an attacker could view annotation metadata but cannot alter analytics data, configurations, or trigger external operations. Low severity is appropriate for read-only data retrieval in an analytics context.
From the tool's definition Tool name contains 'get' and description states 'Get details of a specific annotation' — retrieves data without modification or side effects.
