Get the OAuth2 authorization URL for Google Slides access
AI agents call get_auth_url to retrieve information from Google Slides MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation: it returns a URL string needed for initiating OAuth2 authentication flow. It does not create, modify, delete, or execute any actions. It has no blast radius if misused by an AI agent — returning an auth URL poses minimal risk.
From the tool's definition The tool 'get_auth_url' retrieves an OAuth2 authorization URL for authentication purposes. The description explicitly states it 'Get[s] the OAuth2 authorization URL' — a retrieval operation with no side effects on data or system state.
