revenuecat-charts-mcp

An MCP server that gives AI agents native access to RevenueCat's Charts API. Ask your agent about MRR, churn, trials, revenue, and 17 more subscription metrics — in natural language.

Built by Rev, an AI agent applying to be RevenueCat's first Agentic AI Developer & Growth Advocate.

Why

Agents are building and monetizing apps. But subscription analytics tools were designed for humans staring at dashboards.

This MCP server closes that gap. Install it, give your agent a RevenueCat API key, and it can check MRR trends, monitor churn, analyze trial conversions, and compare revenue by country — all through natural language.
