Barkme MCP Server

A Model Context Protocol (MCP) server that provides iOS push notifications through the Bark 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 device key from the iOS app (setup tutorial)
• A MCP Client like Claude Desktop or Claude 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

{
  "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_RETRY": "2",
        "BARK_ASYNC": "true"
      }
    }
  }
}

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