How to send SMS through SMPP from OobaBooga
This guide explains how to connect OobaBooga to Ozeki SMS Gateway's built in SMS MCP server, enabling the AI assistant to send and receive SMS messages through your own on-premises SMS gateway. You will learn how to install Ozeki SMS Gateway, create an MCP user account, generate an API key, register the MCP endpoint in OobaBooga, and verify the setup by sending a test message.
Solution: How to send SMS from OobaBooga
OobaBooga connects to the SMPP SMS MCP Server through the MCP protocol, where OobaBooga acts as the MCP client and Ozeki SMS Gateway acts as the MCP server. Ozeki SMS Gateway is installed on your local machine or server and connects to the SMS service provider over the internet using an SMPP client connection. When an SMS is sent, it first travels from OobaBooga to the Ozeki SMS Gateway as an MCP tool call, and the gateway forwards it to the SMS service provider over SMPP, which delivers it to the recipient's mobile phone.
What is Oobabooga Text Generation Web UI?
Oobabooga Text Generation Web UI is an open-source web interface for running large language models locally on your own hardware. It supports a wide range of model formats and backends including llama.cpp, as well as GPU-accelerated inference for NVIDIA and AMD graphics cards. It also supports MCP servers, which allows it to be extended with external tools such as SMS messaging.
What is an SMPP SMS MCP Server?
An SMPP SMS MCP Server is a standardized software bridge that uses the Model Context Protocol to connect AI assistants (like Claude) to an SMS gateway system such as Ozeki SMS Gateway, which in turn delivers messages to the mobile network over an SMPP client connection. It exposes tools like "send_message" or "list_incomings" that an AI can autonomously call to perform real-world texting tasks without custom coding. This allows users to simply ask an AI to "send John a reminder text" and have the AI securely execute the action through the server. The SMS MCP Server built into Ozeki SMS Gateway also makes receiving SMS messages possible.

OobaBooga MCP server configuration
# MCP Servers field, format: {url},{Authorization header}
# Replace the address with your SMS Gateway address and the Bearer token with your token
http://{address}:9529/mcp,Authorization: Bearer your-bearer-token
Example prompt
Send an SMS to +36301234567, the message should be "Hello from Oobabooga TextGen".
Add the SMS MCP Server config to OobaBooga
The following video shows how to add the Ozeki SMPP SMS MCP Server to OobaBooga step-by-step.
Open Oobabooga Text Generation WebUI in your browser, then locate and open the sidebar panel on the right side of the interface. Scroll down until you find the MCP servers field, which accepts MCP server entries in a comma-separated format (Figure 1).
In the MCP Servers field, enter the Ozeki SMS Gateway URL followed by a comma and the Authorization header as shown below. Replace the URL with the address of your Ozeki SMS Gateway installation and the Bearer token with the API key you generated for your MCP user account (Figure 2).
http://{address}:9529/mcp,Authorization: Bearer your-bearer-token
Send a test SMS
The following video shows how to send an SMS message from Oobabooga Text Generation WebUI using the Ozeki SMPP SMS MCP server step-by-step.
In the Oobabooga chat input, type your SMS request in plain language and press the Send button. The AI model will interpret the request, select the appropriate MCP tool, and invoke it to deliver the message through the gateway (Figure 3).
Send an SMS to +36301234567, the message should be "Hello from Oobabooga TextGen".
The tool result will appear in the Oobabooga chat. A successful response confirms that the message was submitted to the gateway and handed off for delivery (Figure 4).
Check the SMS in the SMS Gateway logs
The following video shows how to check the SMS in the logs in Ozeki SMS Gateway step-by-step.
Open Ozeki SMS Gateway in your browser and navigate to the MCP user details page by clicking on the MCP user entry in the Users and applications panel (Figure 5).
In the event log, you should see an entry for the outgoing message, including the recipient number and message text, confirming that it was successfully processed by the gateway (Figure 6).
Conclusion
In this guide, you have learned how to connect Oobabooga WebUI to Ozeki SMS Gateway's built-in SMS MCP Server and use it to send SMS messages directly from the chat interface. By installing the gateway, setting up an SMPP connection to the mobile network, creating an MCP user account, and registering the MCP endpoint in OobaBooga, you now have a fully functional on-premises SMS integration that your locally hosted AI model can use to communicate with any mobile phone.
