Quackr MCP is an official MCP server for Quackr — virtual phone numbers for SMS verification and OTP receipt. It lets MCP-compatible clients like Claude check pricing and inventory, purchase temporary numbers, and read incoming SMS programmatically.
Configure it in your MCP client with the hosted endpoint https://mcp.quackr.io/ and an Authorization: Bearer YOUR_API_KEY header. Use the CLI command claude mcp add --transport http quackr https://mcp.quackr.io/ --header "Authorization: Bearer YOUR_API_KEY_HERE" or add it to your ~/.claude.json. For Claude Desktop, add it as a custom connector in Settings → Connectors with the same header.
