FAQ
ASO MCP questions
Yes. Add the hosted server at https://trysonar.app/mcp and sign in: the first time a tool needs your account, your browser opens the Sonar sign-in. Claude Code, Codex, Cursor, Claude and ChatGPT all support it (in ChatGPT, open the Sonar app and connect it). Without an account, free mode serves the core research tools (app search, app lookup, ASO score, keyword extraction, keyword suggestions, keyword metrics and top charts) with daily limits per IP. API keys are for scripts, CI, the CLI and the local npm package.
Run claude mcp add --transport http sonar https://trysonar.app/mcp, then ask a question. Claude Code opens your browser to sign in the first time a tool needs your account. Guides for Codex, Cursor, Claude and ChatGPT are on the Connect your AI page.
An App Store Optimization MCP server exposes ASO data (keyword metrics, rankings, reviews, listing metadata) as tools an AI agent can call through the Model Context Protocol. Instead of copying numbers out of a dashboard, your agent researches keywords, checks rankings and analyzes competitors right in the conversation.
Anything that speaks MCP: Claude Code, Codex, Cursor, Claude (desktop and web), ChatGPT, Cline, Windsurf and custom agents built on the MCP SDK. Use the hosted URL and sign in, or run @sonarapp/mcp locally with npx. ChatGPT uses the Sonar app instead of a URL.
Everything the Sonar API does: keyword research with difficulty and Apple's own search popularity on iOS, ASO audits, review mining, revenue estimates, daily rank tracking and competitor gap analysis. Write tools let your agent set up tracking and read the results back over time.
Scraper MCP servers return raw listing data. Sonar's tools return computed ASO metrics: keyword difficulty, Apple-reported search popularity, validated rankings, ASO audit scores and revenue estimates.
Free mode needs no account. Signing up adds 50 free credits; prepaid packs start at $10 (no subscription, credits never expire). The Indie plan ($29/mo) adds tracking for 10 apps and 2,500 keywords with daily rank history your agent can query.
