Get current API subscription info, usage and remaining quota
AI agents call get_subscription_info to retrieve information from Majestic 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 read-only information about subscription status, API usage, and quota limits. It queries existing data without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an attacker learns about account status and usage patterns but cannot modify resources, execute operations, or cause financial transactions.
From the tool's definition Tool name 'get_subscription_info' and description 'Get current API subscription info, usage and remaining quota' indicate retrieval of account/usage metadata with no modification or side effects.
