```

### Manual Installation

Configure Claude for Desktop:

Open your Claude for Desktop App configuration at `~/Library/Application Support/Claude/claude_desktop_config.json` and add:

```json
{
    "mcpServers": {
        "bluesky-mcp": {
            "command": "npx",
            "args": ["-y", "@semihberkay/bluesky-mcp"],
            "env": {
                "BLUESKY_IDENTIFIER": "your.handle.bsky.social",
                "BLUESKY_PASSWORD": "your-app-password"
            }
        }
    }
}
```

### Required Environment Variables
