Get current billing period usage including streaming minutes, storage, and bandwidth consumption
AI agents call wave_get_usage to retrieve information from WAVE 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 billing usage metrics (streaming minutes, storage, bandwidth consumption) without modifying, deleting, or committing any financial transactions. It is a simple data query operation with no side effects. While the data concerns billing, the tool itself does not move money or create obligations—it only reads usage statistics. Therefore, it falls under the Read category with low severity.
From the tool's definition Tool name 'wave_get_usage' and description 'Get current billing period usage' indicate data retrieval only. The verb 'Get' and the absence of any modification, creation, deletion, or financial transaction language confirms read-only behavior.
