Verdict

Pick Infobip MCP Servers if you want a hosted/remote server with nothing to install, and you need the broadest set of tools.

Pick Slack MCP Server (korotovsky) if you prefer the more popular, battle-tested option, and you want a local (stdio) server that keeps data on your machine.

Add Infobip MCP Servers

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

  "mcpServers": {
    "infobip-mcp-servers": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.infobip.com/sms",
        "--header",
        "Authorization: App ${INFOBIP_API_KEY}"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
