# Barkme MCP Server

[![smithery badge](https://smithery.ai/badge/@vibeworks/barkme-mcp-server)](https://smithery.ai/server/@vibeworks/barkme-mcp-server)

A Model Context Protocol (MCP) server that provides iOS push notifications through the [Bark](https://bark.day.app/) service. Send notifications directly from Claude conversations with a simple, intelligent interface.

## Features

- **Single Tool Interface**: One `notify` tool handles all notification scenarios
- **Device Aliases**: Use friendly configurable aliases like "iPhone:key1", "macOS:key2" instead of exposing device keys to AI
- **Async-First**: Non-blocking notifications with background delivery and structured logging
- **Complete Bark API Support**: All 20+ parameters including encrypted messages and notification management
- **Update/Delete Notifications**: Modify or remove previously sent notifications using notification IDs

## Quick Start

### Prerequisites

- Node.js 20+
- A [Bark](https://bark.day.app/) device key from the iOS app ([setup tutorial](https://bark.day.app/#/tutorial))
- A MCP Client like [Claude Desktop](https://claude.ai/desktop) or [Claude Code](https://claude.ai/code)

### via npmjs


#### Claude Desktop Integration

Add to your Claude Desktop configuration file:

- **macOS/Linux**: `~/.config/claude-desktop/claude_desktop_config.json`
- **Windows**: `%AppData%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "barkme": {
      "command": "npx",
      "args": ["@vibeworks/barkme-mcp-server"],
      "env": {
        "LOG_LEVEL": "info",
        "BARK_DEVICES": "iPhone:<your key>",
        "BARK_SERVER": "https://api.day.app",
        "BARK_GROUP": "Claude",
        "BARK_RETRY": "2",
        "BARK_ASYNC": "true"
      }
    }
  }
}
```


*Restart Claude Desktop* after adding the configuration. The Barkme server will appear in the MCP tools section.
