   cd etf-flow-mcp
   ```

2. **Set Up with uv**:

## Usage

### Integrating with Claude Desktop

1. **Configure Claude Desktop**:
   Add the server to `claude_desktop_config.json` (located in `~/Library/Application Support/Claude` on macOS or `%APPDATA%\Claude` on Windows):
   ```json
   {
     "mcpServers": {
       "etf-flow-mcp": {
         "command": "uv",
         "args": ["--directory", "/absolute/path/to/etf-flow-mcp", "run", "etf-flow-mcp"],
         "env": { "COINGLASS_API_KEY": "your_coinglass_api_key_here" }
       }
     }
   }
   ```
   Replace `/absolute/path/to/etf-flow-mcp/cli.py` with the full path to `cli.py`.

2. **Restart Claude Desktop**:
   Verify the hammer icon appears in the Claude Desktop UI to confirm the server is loaded.

3. **Query Examples**:
   - "Show me the latest BTC ETF flow data in a table"
   - "Get the ETH ETF flow history"
