How to use the Android MCP SMS Server in Jan

This guide explains how to connect the Ozeki Android SMS Gateway MCP server to Jan, enabling the AI assistant to send SMS messages directly from your Android phone. By following this tutorial, you will learn how to install the Ozeki Android SMS Gateway app, enable its built-in MCP server, register the MCP endpoint in Jan, and verify that everything is working by sending a test message.

Solution: How to send SMS from Jan

Jan is connected to the Ozeki Android SMS MCP Server through the MCP protocol, where Jan is the MCP client and the Android phone is the MCP server. The Android phone is connected to the SMS service provider through a wireless mobile network connection. When an SMS is sent, it first travels from Jan to the Android phone through the MCP protocol, and the Android phone forwards it to the SMS service provider, which delivers it to the recipient's mobile phone.

What is Jan?

Jan is an open-source desktop application that allows you to run large language models locally on your own hardware. It provides a clean chat interface, supports a wide range of model formats, and can be extended with MCP servers to add external tool capabilities such as SMS messaging, database access, and more.

What is an Android SMS MCP Server?

An Android SMS MCP Server is a Model Context Protocol server that runs directly on an Android smartphone and exposes SMS functionality — such as sending text messages and querying SIM subscriptions — as structured tools that any MCP-compatible AI client can call. Once installed and configured, the AI client can send real SMS messages through the phone's SIM card to any phone number, with a single tool call.

Steps to follow

You will need Jan installed on your system. If you have not set it up yet, follow our Jan installation guide.

1. Install Ozeki Android SMS Gateway
2. Enable MCP SMS Server
3. Jan SMS MCP Server Config
4. Add the SMS MCP Server config to Jan
5. Send a test SMS
6. Check the SMS in the SMS Gateway logs

Step 1 - Install Ozeki Android SMS Gateway

For a full tutorial on installing the Ozeki Android SMS Gateway, check out our How to install Android SMS Client and Enable Ozeki SMS Client permissions guides.

Before you can use the MCP SMS Server, you need to install the Ozeki SMS Client on your Android device. The app will serve as the local SMS gateway that Jan connects to over your Wi-Fi network. Make sure both devices are on the same local network, as this is required for the HTTP connection to work.

Step 2 - Enable MCP SMS Server

For a full tutorial on enabling the MCP server in the Android app, check out our Android MCP SMS Server configuration guide.

Open the Ozeki SMS Client app on your Android device and tap the MCP tab in the bottom navigation bar. Tap the toggle switch to start the MCP server and grant any permission requests that appear, including access to SMS messages. The toggle will switch from "Stopped" to "Running" and the API endpoint URL will appear below. Copy this URL, as you will need it when configuring Jan in the next step.

Step 3 - Jan SMS MCP Server Config

Server Name: Android SMS MCP
Transport Type: HTTP
URL: http://{address}:9531/mcp
Timeout (seconds): 120

Enable "Tools" in the Provider -> Models -> Model edit -> Capabilities

Example prompt

Send an SMS to +36301234567, the message should be "Hello from Jan".

Step 4 - Add the SMS MCP Server config to Jan

The following video shows how to add the Android SMS MCP server to Jan step-by-step. It covers navigating to the MCP server settings, registering the server, and enabling tool use on the configured model.

Open Jan and navigate to Settings. Select the MCP Servers section from the left-hand menu, where all external MCP tool servers can be registered (Figure 1).

Click the Add New MCP Server button to open the server registration form (Figure 2).

Fill in the MCP server details in the registration form. Set the Server Name to Android SMS MCP, the Transport Type to HTTP, the URL to the endpoint shown in the Ozeki SMS Client app on your Android device, and the Timeout to 120 seconds. Click Save to register the server (Figure 3).

Server Name: Android SMS MCP
Transport Type: HTTP
URL: http://{address}:9531/mcp
Timeout (seconds): 120

For the AI model to be able to call MCP tools, tool use must be enabled in the model's capabilities settings. In Jan's Settings, navigate to your AI provider and open its configuration page. In this case, open the Ozeki AI Gateway provider that you have set up previously (Figure 4).

In the provider configuration, find the model you want to use and click the Edit button next to it. Each model in Jan can be individually configured with its own set of capabilities (Figure 5).

In the model edit view, enable the Tools toggle in the Capabilities section. This tells Jan that the model is allowed to call external MCP tools during a conversation. Click Save Changes to apply the change (Figure 6).

Step 5 - Send a test SMS

The following video shows how to send an SMS message from Jan using the Ozeki Android SMS MCP server step-by-step.

Start a new chat in Jan and select the provider and model for which you enabled tool use in the previous step (Figure 7).

Type a plain language instruction in the chat prompt asking the AI to send an SMS to a specific phone number. Jan will call the Send SMS tool and process the request (Figure 8).

Send an SMS to +36301234567, the message should be "Hello from Jan".

Jan may prompt you to approve the tool use before proceeding. This is a security confirmation to ensure you are aware that an external tool is being called on your behalf. Confirm the action to allow the AI to send the SMS (Figure 9).

You will see the result of the Send SMS tool call in the chat window. A successful response confirms that the message has been passed to the Android gateway and queued for delivery (Figure 10).

Step 6 - Check the SMS in the SMS Gateway logs

The following video shows how to check the gateway logs in the Ozeki SMS Client app step-by-step. This allows you to confirm that the SMS request from Jan was received and processed successfully by the Android gateway.

Open the Ozeki SMS Client app on your Android device and navigate to the Settings tab in the bottom navigation bar to access the application settings. Tap the Log option to view the request and response history (Figure 11).

Select the MCP tab to show only MCP-related activity. Here you will see the incoming tool call requests from Jan and the responses sent back, allowing you to confirm that the SMS was dispatched successfully (Figure 12).

Summary

You have successfully configured the Ozeki Android SMS Gateway MCP server with Jan. Your Android device is now acting as a local SMS gateway that it can communicate with over your local network, enabling text messages to be sent to any phone number using plain language prompts. All SMS traffic is routed through your Android device's mobile connection, with no cloud messaging API or third-party service required.
