sonar — Claude Code MCP server: ASO tools for agents
Hands your agent App Store and Google Play data: app lookup, keyword research, ASO audits, review mining and revenue estimates.
claude mcp add --env SONAR_API_KEY=<SONAR_API_KEY> --env SONAR_API_URL=<SONAR_API_URL> --transport stdio sonar -- npx -y @sonarapp/mcpWhat sonar does
The server exposes 55 tools from the Sonar REST API. Several read calls run keyless: app search, ASO scoring, keyword extraction from a listing, autocomplete suggestions and top charts. The rest need an API key and credits on any plan.
Access then splits by plan. Workspace tools — tracked apps, rank history, metadata changes, review analysis, alerts — open up on Indie or higher. Portfolio rollups plus App Store Connect sales and funnel data sit behind Agency, and other plans get a 403. Anything that writes to your workspace needs a write-scope key or an OAuth sign-in.
The two AI generation tools, sonar_analyze_competitors and sonar_generate_review_insights, are unavailable on a trial and require a paid plan. sonar_app_sales and sonar_app_engagement also need an App Store Connect connection, and the funnel numbers want an Admin-role key. Both are iOS-only.
What it helps with
- find apps for a keyword and see their store ranking order
- score a listing against an ASO checklist
- pull target keywords out of an app description
- compare your keywords with a competitor's and spot the gaps
- watch daily ranks and catch rating drops
Example prompts for the agent
- Find apps in the App Store for "habit tracker" and show the ranking order
- Run an ASO audit on the app with ID 123456789 and tell me what to fix
- Pull my competitor's keywords and show where my app has gaps
