Get app ratings distribution
AI agents call ratings to retrieve information from Store Scraper MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing rating data from app stores. It performs a read-only operation with no capability to modify, delete, or execute actions. The blast radius of misuse is minimal—an agent could only over-query or spam requests, not compromise data integrity or trigger unintended side effects.
From the tool's definition Tool name 'ratings' and description 'Get app ratings distribution' indicate data retrieval with no side effects. The server description confirms it 'retrieves data from App Store and Google Play Store, including...ratings'.
