API and MCP server

Everything on AppInsider, in your own tools: a JSON API for scripts and dashboards, and an MCP server so Claude, ChatGPT, Cursor and other AI assistants can answer questions from live app data.

MCP server for AI assistants

Add AppInsider as a remote MCP server (streamable HTTP) and your assistant can look up charts, downloads, revenue, active users, keywords and market size while it works.

Claude (claude.ai or the desktop app): Settings → Connectors → Add custom connector, and paste your URL with the key in it:

https://appinsider.io/mcp.php?key=YOUR_API_KEY

Other clients that let you set headers: URL https://appinsider.io/mcp.php with Authorization: Bearer YOUR_API_KEY. Or through mcp-remote:

{
    "mcpServers": {
        "appinsider": {
            "command": "npx",
            "args": [
                "mcp-remote",
                "https://appinsider.io/mcp.php",
                "--header",
                "Authorization: Bearer ${APPINSIDER_KEY}"
            ],
            "env": {
                "APPINSIDER_KEY": "ai_…"
            }
        }
    }
}
