Test Gemini API connection
AI agents call test_gemini_connection to retrieve information from Gemini MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Testing a connection is a read-only diagnostic operation with no side effects; it queries the API endpoint to confirm availability without creating, modifying, or deleting any data. Low severity since misuse has minimal blast radius.
From the tool's definition 'Test Gemini API connection' — a connectivity/health-check operation that verifies the API is reachable
