How to Use

1. In the Browser (Demo or Live Data)

Click "Launch App" above. Enter your MarketCheck API key in the settings gear for live data, or explore with demo data.

Chat apps also require an LLM API key (Anthropic, OpenAI, or Google Gemini).

2. As an MCP App (AI Assistants)

Add the MarketCheck MCP server to Claude, VS Code, or any MCP-compatible host:

{
  "mcpServers": {
    "marketcheck-apps": {
      "url": "https://apps.marketcheck.com/mcp?api_key=YOUR_KEY"
    }
  }
}

Then ask the AI to use the chat tool.
