openaso — App Store Optimization for AI agents

openaso is a hosted MCP server that gives AI agents real App Store Optimization data from Apple's public app-store APIs: keyword ranks, search-autocomplete suggestions, keyword popularity (real Apple Search Ads popularity where available), competitor intelligence, review mining, chart positions, local metadata keyword-coverage analysis, and account-scoped daily rank tracking.

• Website / signup: https://openaso.ai
• Endpoint: https://mcp.openaso.ai/mcp (Streamable HTTP, stateless)
• Official MCP registry: ai.openaso/openaso
• Docs: https://openaso.ai/docs · tool contracts: https://openaso.ai/tools
• Agent-readable docs: https://openaso.ai/llms.txt and https://openaso.ai/llms-full.txt (every docs page is also served as markdown at its URL + .md)

This repository is the public home of openaso: connection docs, examples, and the issue tracker. The server's source code is proprietary and is not published here.

Quick start

1. Create a free account and mint an API key at https://openaso.ai (free tier: 500 tool calls/day, 500 tracked app × keyword × storefront combinations).
2. Connect your client.

Claude Code

claude mcp add openaso --transport http https://mcp.openaso.ai/mcp \
    --header "Authorization: Bearer YOUR_KEY"

Any MCP client (JSON config)

{
  "mcpServers": {
    "openaso": {
      "url": "https://mcp.openaso.ai/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Authentication is Authorization: Bearer <key> (an x-api-key header also works).

Tools

Everything is per-storefront: ranks, availability, suggestions and popularity differ by country, so tools take an explicit countries list (default ["US"]).

Why agents like it

Apple indexes an app's title (30 chars), subtitle (30) and hidden keyword field (100) as one combined word pool — an app can rank for any query assembled from words across those fields. openaso's tools are built around that model: audit finds the candidates, coverage scores a draft's pool locally, rank/volume verify against the real store. The full model is explained in the docs (agents: llms.txt).
