Open-source MCP server for live Apple App Store competitor research
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"appstore-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# appstore-mcp <!-- mcp-name: io.github.laurmost/appstore-mcp --> An open-source MCP server for live Apple App Store competitor research. It lets AI agents search apps, fetch public App Store metadata, compare competitors side by side, and retrieve reviews and top charts as structured JSON — for market research, ASO research, and product analysis. It works with public competitor data only. The default, recommended `uvx` setup below needs no Apple developer account, no API keys, and no database (a separate, optional hosted alternative does require an API key — see [Hosted deployment](#hosted-deployment)). > Compare Duolingo, Babbel, and Busuu on the US Apple App Store. ## Setup Requires [uv](https://docs.astral.sh/uv/). Add to your MCP client config: ```json { "mcpServers": { "appstore": { "command": "uvx", "args": ["appstore-mcp"] } } } ``` - **Claude Code**: `claude mcp add appstore -- uvx appstore-mcp`, or install as a plugin: `/plugin marketplace add LaurMost/appstore-mcp` then `/plugin install appstore-mcp` - **Claude Desktop**: add the snippet above to `claude_desktop_config.json` - **Cursor**: add the snippet above to `~/.cursor/mcp.json` If your MCP client can't find `uvx`, use the absolute path from `which uvx` as the `command`. ## Hosted deployment The `uvx` setup above is still the primary, recommended way to use this server — it needs no API key. A hosted HTTP instance is also available at `https://appstore-mcp.fastmcp.app/mcp` for MCP clients that need a network-accessible endpoint instead of a local stdio process. It requires an API key, sent as an `Authorization: Bearer <key>` header. See [docs/adr/0012-additive-hosted-http-mode.md](docs/adr/0012-additive-hosted-http-mode.md) for why this is additive rather than a replacement, and the trade-offs involved. ## Tools | Tool | What it does | | --- | --- | | `search_app_store` | Search apps by keyword (slim results: id, name, developer, rating, price) | | `get_app_st…
