Hi everyone,

I recently built an open-source project for TP-Link TL-MR100 routers that provides a local web interface for managing SMS messages directly through the router.

🔗 GitHub: https://github.com/Incognito-Coder/TP-Link-MR100-SMS

 

What is it?

MR100 SMS Desk is a lightweight, completely local Node.js application that communicates with the router’s internal SMS interface.

Instead of relying on the router’s built-in web interface, the project provides a dedicated dashboard for managing SMS messages.

 

✨ Features

• 📥 Read Inbox messages
• 📤 View Sent messages
• 📝 Create and manage Drafts
• ✉️ Send SMS messages
• 🗑️ Delete SMS messages
• ✅ Mark messages as read
• 🌍 Support for both GSM-7 and Unicode SMS
• 📱 Multipart SMS support
• 🇮🇷 Proper Persian / RTL message rendering
• 🔐 Implements the router’s encrypted login and API communication
• 🔒 Credentials, cookies, encryption keys and SMS data are kept in memory only
• 🌐 Runs locally on 127.0.0.1 by default
• 🚫 No cloud service or third-party server is required

The project reverse-engineers and implements the encrypted communication used by the MR100’s /cgi_gdpr interface, including the RSA/AES-based authentication and request protocol.

🖥️ Standalone Builds

The project can also be compiled into standalone executables, so Node.js does not need to be installed on the target computer.

 

Currently supported builds include:

• Windows x64
• Linux x64
• Linux ARM64
• macOS ARM64

 

🔧 Requirements

For running from source:

• Node.js 22+
• A computer connected to the same LAN as the router
• A compatible TP-Link MR100 router

After starting the application, simply open:

http://127.0.0.1:3781

and enter your router’s local IP address, username and password.

 

⚠️ Compatibility

This first release targets the legacy MR100 firmware communication protocol using AES-128-CBC.

Some newer firmware versions use AES-GCM with a separate authentication tag and are not currently supported.

I created this project primarily because I wanted a simple way to access and manage the MR100’s SMS functionality from a computer without depending on the router’s original web interface.

I’d be very interested to hear from other MR100 owners about their hardware/firmware versions and whether the project works for them.

If you have a different MR100 firmware version, please share the hardware version and firmware version so compatibility can be investigated.

 

Feedback, testing results, bug reports and contributions are very welcome! 🙌
