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.
