Introducing Msg2AgentBuilder
The First Open-Source Bridge Between Text Messaging and OpenAI Agents
Today marks a really exciting milestone for anyone building AI tools, automation workflows, or customer-facing messaging systems. Msg2AI just released its first open-source software project: Msg2AgentBuilder, a lightweight but powerful connector that lets you plug everyday text messages straight into OpenAI's Agent Builder platform.
If you've ever wished your AI agent could respond to real-world conversations coming from SMS, WhatsApp, or other chat channels, this project basically hands you that power on a silver platter. And the best part is that it's totally open-source, which means you can study it, modify it, scale it, or build something completely new on top of it.
What Msg2AgentBuilder Does
The idea behind the project is simple but game-changing. Instead of forcing users to open an app or log into a dashboard, your AI agent becomes reachable directly through text messaging. Parents asking about their kid's sports schedule, guests messaging a hotel, customers texting a business, students asking for support... all of that can now flow through an OpenAI agent automatically.
The image above sums it up nicely: OpenAI's Agent Builder on one side, real-world conversations on the other, and Msg2AgentBuilder is the pipe in the middle that keeps everything moving.
What's Inside the GitHub Release
The full open-source repository is here:
👉 https://github.com/msg2ai/msg2agentbuilder
Inside the repo, you'll find:
- Clear setup instructions
- A simple and clean code structure
- Built-in support for webhooks
- Message forwarding to OpenAI agents
- Examples you can copy and adapt
- A ready-to-run local environment
Anyone with basic Node.js experience can get this running in under ten minutes.
Video Walkthrough
If you like learning by watching instead of reading, there's a full installation walkthrough here:

The video breaks down:
- How to clone the repo
- How to configure your environment
- How to connect a phone number
- How to route inbound messages to your agent
- How to test everything live
It's beginner-friendly and really helpful if you want to follow along step by step.
Why This Release Matters
There are tons of AI tools out there, but very few open-source projects that connect AI to the communication channels people actually use every day. Texting is still the most universal format out there, and making it "AI-ready" opens the door to some wild possibilities:
- AI-powered customer service
- Smart attendance systems
- Rental property messaging
- School or sports communication
- Appointment reminders
- Automated Q&A systems
- Anything you want to handle with an agent
With Msg2AgentBuilder being open-source, developers get full transparency and total control, which is honestly a huge deal for anyone tired of black-box platforms.
A Solid First Step for the Msg2AI Open-Source Ecosystem
This release is just the start. Msg2AI is already rolling out agents across hotels, properties, events, sports programs, and even universities, and opening up their tools means a bigger community can shape what comes next.
If you build anything cool with Msg2AgentBuilder, the team would love to see it. Fork it, remix it, ship your own version, or plug it into something nobody's ever tried before.
