AI Executive Synthesis
A cost-effective, self-hosted alternative to commercial SMS APIs (e.g., Twilio) for agent-based systems, leveraging existing hardware for OTP access and SMS communication.
This solution directly addresses the cost and complexity associated with commercial SMS APIs for agent-based systems. By repurposing an old Android phone and a simple relay server, it provides a highly cost-effective mechanism for agents to access OTP codes and send SMS messages. This is particularly relevant for internal tools, testing environments, or niche applications where Twilio's pricing or setup overhead is prohibitive. The ability to self-host on a low-cost VPS offers significant operational flexibility and cost control. While not a scalable enterprise solution in its current form, it highlights a market demand for pragmatic, low-cost communication channels for automated systems, especially for two-factor authentication bypass or internal notification systems. This could evolve into a more robust, open-source alternative for specific use cases.
While playing with agents I realised it might be quite handy if they could get access to OTP codes. And while at it, why not give them ability to send the SMS as well. Twillio is expensive and annoying to set up for my taste.I vibe coded simple Android app that can read/send SMS and simple relay server that acts as MCP for agents. Works surprisingly well and my old android phone from a drawer is doing something useful again.Feel free to use it if you find it useful. I put it just to a $5 vps. If it's crashed, you should be able to spin up your own instance on your own VPS just in a few minutes.
