Get current subscription details including plan, billing cycle, and feature entitlements
AI agents call wave_get_subscription 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 is a read-only query operation that retrieves subscription metadata. While it accesses billing-related information (plan, billing cycle), it does not execute financial transactions, move money, or create financial obligations. It is strictly informational and has no write or destructive impact.
From the tool's definition Tool name uses 'get' and description states 'Get current subscription details including plan, billing cycle, and feature entitlements' — purely retrieves subscription information without modification, payment, or side effects.
