AppSigma App Store MCP

AppSigma provides an official MCP server that exposes 22 tools for App Store Optimization (ASO). It allows AI agents to access keyword rankings, app metadata, review sentiment analysis, chart history, and competitor data. This enables automated tracking of app performance, identification of ranking opportunities, and analysis of user feedback directly within AI development environments like Claude, Cursor, and ChatGPT.
