AI & automation

Use Sonar from Claude Code, Codex or Cursor

Add the hosted server once and the agent you already build with can call all 63 Sonar tools — keyword research, rankings, competitors and reviews, on both stores.

  • Free mode works without an account or API key
  • Live store data, not the model’s training data
  • REST API (1,000 req/day) and the sonar CLI on Indie
Setup instructions
Terminal
claude mcp add --transport http sonar https://trysonar.app/mcp

Codex, Cursor and Claude take one command or config block each. Without an API key, the hosted server runs in free mode.

How it works

From prompt to top-10 ranking

The same agent session that ships your code can run your ASO: research, a listing draft, and daily tracking.

Connect

Add Sonar to Claude Code, Codex, Cursor or Claude in two minutes. Free mode works without an account.

Ask

Ask in plain English. Your agent pulls search popularity, difficulty and competitor keywords for every country.

Ship

It drafts your name, subtitle and keyword field in every language for you to review.

Track

Sonar checks your rankings every day, and your agent reports what moved.

Proof

What an agent did for my own app

ReelMeal is my iPhone app. I handed its ASO to an agent running on Sonar. Real numbers from App Store Connect, including what went wrong.

An agent localized the listing for 35 storefronts

  • 0 → 47 top-10 keywords in two days
  • 19 → 90 first-time downloads a month

Draft the listing in every language

FAQ

Frequently asked questions

Claude Code, Codex, Cursor and Claude, plus any other client that speaks MCP. Add the hosted server (trysonar.app/mcp) or run the @sonarapp/mcp npm package — both expose the same 63 tools. If your agent prefers the shell or plain HTTP, the same data is in the sonar CLI and the REST API.

Your agent researches keywords and drafts your name, subtitle and keyword field in every language for you to review. On Indie, its write tools also add your app, competitors and keywords to rank tracking. Publishing stays with you: Sonar does not edit your listing in App Store Connect, so you paste in the version you approve.

Yes. Free mode needs no account: add the hosted server without an API key and the core research tools — app search and lookup, ASO score, keyword extraction, keyword suggestions, keyword metrics and top charts — work with daily limits per IP. Rank tracking and the workspace tools start with the 7-day free trial, which needs a card.

Give your agent the App Store

Connect Sonar, ask where your app ranks, and let your agent find the keywords your competitors missed. Takes about two minutes.
