Set up Sonar in Claude Desktop

Add a custom connector, then sign in — no API key. Once connected, Claude Desktop can look up apps, research keywords, audit ASO, mine reviews, and estimate revenue — live from the App Store and Google Play.

Add Sonar and sign in — no API key

Claude Desktop connects to the hosted Sonar server. The first time a tool needs your account, your browser asks you to sign in to Sonar — nothing to install, no key to copy. No account yet? Start a free trial. In Claude Desktop or claude.ai, open Settings → Connectors → Add custom connector and paste the URL:

Hosted — sign in, no API key

Settings → Connectors → Add custom connector (Claude Desktop and claude.ai). The first time a tool needs your account, your browser asks you to sign in to Sonar.

Verify it works

Start a new chat — the 63 sonar_* tools appear under the Sonar connector. Using the config file instead? Fully quit Claude Desktop (Cmd+Q — closing the window isn't enough) and reopen it.

Try this first prompt

Use Sonar to run an ASO audit on Duolingo on iOS in the US store. Summarize the score and the top 3 fixes you'd make first.

What you get back: a 0–100 ASO score with itemized checks, turned into a prioritized fix list by your AI.

Prefer an API key?

For scripts, CI, the sonar CLI or the local @sonarapp/mcp server (runs via npx, no global install). Create a key in Settings → Developers — keys start with aso_, and new accounts get 50 free credits on signup. Then replace aso_your_key_here below.

With an API key (scripts, CI, local): claude_desktop_config.json

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "sonar": {
      "command": "npx",
      "args": ["-y", "@sonarapp/mcp"],
      "env": {
        "SONAR_API_KEY": "aso_your_key_here"
      }
    }
  }
}

Connected? Raid the prompt library.

Copy-paste prompts for keyword gaps, review mining, ASO audits, localization, and launch tracking — they work as-is in Claude Desktop. On the Indie plan, AI can even set up your workspace — add your app, link competitors, track keywords.
