Ask your agent things like

  • “Which meditation apps make over $100K/month with under 5,000 ratings?”
  • “Find habit trackers earning well with fewer than 2,000 ratings.”
  • “What are users complaining about in the latest reviews of my competitor?”
  • “Compare two indie budgeting apps: downloads, revenue and ratings.”
  • “Which keywords does my app rank for that my closest competitor does not?”

How it works

The server implements the MCP Streamable HTTP transport at https://www.appstro.dev/api/mcp and is fully stateless — no sessions, no auth. Under the hood it queries the same public data sources that power appstro.dev: Apple's iTunes APIs, public download/revenue estimates, and the Google Ads Transparency Center. Please use it fairly; heavy automated scraping may be rate-limited.
