SMS gateway → sms8.io · SMS Gateway MCP for vibe coders & developers → mcp.sms8.io Send SMS, issue and verify OTPs, wait for incoming codes, and configure webhooks from Claude Code, Cursor, Windsurf, OpenCode and any other AI coding tool that speaks the Model Context Protocol. SMS routes through a paired Android phone via the SMS8 platform. Live server: https://mcp.sms8.io Dashboard: https://app.sms8.io Marketing site: https://sms8.io Building an app and want SMS notifications, OTPs, two-way messaging, or autonomous-agent phone verification? Most options force you to register with carrier programs, provision phone numbers, pay per message, or rent a disposable SIM per session. SMS8 routes SMS through a phone you already own. The MCP server gives your AI assistant nine tools it can call directly, so adding SMS to a project takes one prompt instead of an hour of integration work.
