Install the MCP server

Published on npm as @sonarapp/mcp. Runs over stdio. No global install needed.

Claude Code

One-liner from your shell:

claude mcp add sonar \
  -e SONAR_API_KEY=aso_... \
  -- npx -y @sonarapp/mcp

Restart your session and all 63 sonar_* tools will be available.

Cursor, Claude Desktop and other clients

Add to your client's MCP config:

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

Available endpoints

10 stateless endpoints covering app lookup, keyword research, reviews, ASO scoring, revenue estimates, and top charts. All are exposed as MCP tools, and callable directly via REST.

MethodEndpoint
GET/api/v1/apps/lookup
GET/api/v1/apps/search
GET/api/v1/apps/aso-score
GET/api/v1/apps/extract-keywords
GET/api/v1/apps/reviews
GET/api/v1/apps/revenue
GET/api/v1/keywords/metrics
GET/api/v1/keywords/search
GET/api/v1/keywords/suggestions
GET/api/v1/charts/top

Or call the API directly

Standard REST API with Bearer token auth. Works with any HTTP client, agent framework, or automation tool — same data as the MCP server.

curl -H "Authorization: Bearer aso_your_api_key" \
  "https://api.trysonar.app/api/v1/apps/lookup?store=ios&id=com.example.app"

All responses return { "data": ... } on success or { "error": { "code": "...", "message": "..." } } on failure. See the full API reference or the OpenAPI 3.1 spec.

Or use it from your terminal

The companion @sonarapp/cli package exposes the same data via a sonar binary — for shell scripts, CI/CD, and one-off lookups.

npm install -g @sonarapp/cli
sonar auth login
sonar keywords search "habit tracker" --store ios --table
