How to use the Android MCP SMS Server in Cherry Studio
This guide explains how to connect the Ozeki Android SMS Gateway MCP server to Cherry Studio, 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 Cherry Studio, and verify that everything is working by sending a test message.
Solution: How to send SMS from Cherry Studio
Cherry Studio is connected to the Ozeki Android SMS MCP Server through the MCP protocol, where Cherry Studio 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 Cherry Studio 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 Cherry Studio?
Cherry Studio is an open-source, cross-platform desktop AI client that supports multiple AI providers including OpenAI, Anthropic, Google, and locally hosted models. It features a clean chat interface, document management, and MCP server support, enabling it to be extended with external tools 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.

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 Cherry Studio 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 Cherry Studio in the next step.
Step 3 - Cherry Studio SMS MCP Server Config
# Navigate to: Settings -> MCP Servers -> Add Server -> Add Custom Server
# Replace {address} with your Ozeki Android SMS Gateway address
Name: Ozeki Android SMS MCP
Type: Streamable HTTP
URL: http://{address}:9531/mcp
Example prompt
Send an SMS to +36301234567, the message should be "Hello from Cherry Studio".
Step 4 - Add the SMS MCP Server config to Cherry Studio
The following video shows how to add the Android SMS MCP server to Cherry Studio step-by-step. It covers navigating to the MCP Servers settings, creating the server entry, connecting to the gateway, and verifying the available tools.
Open Cherry Studio 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 button and select Quick Create from the dropdown menu. This opens a streamlined form for registering a new MCP server without requiring a full JSON configuration (Figure 2).
Fill in the MCP server details in the Quick Create form. Enter a descriptive Name such as Ozeki Android SMS MCP, set the Type to Streamable HTTP, and enter the URL shown in the Ozeki SMS Client app on your Android device. Click the Connect toggle to establish the connection (Figure 3).
Name: Ozeki Android SMS MCP
Type: Streamable HTTP
URL: http://{address}:9531/mcp
Navigate to the Tools tab in the MCP server entry to view the tools exposed by the server (Figure 4).
Step 5 - Send a test SMS
The following video shows how to send an SMS message from Cherry Studio using the Ozeki Android SMS MCP server step-by-step.
Start a new chat in Cherry Studio and enable Auto Tool Use by clicking the tools icon in the chat toolbar. This allows the AI assistant to automatically call MCP tools, including the Send SMS tool, when relevant to the conversation (Figure 5).
Type a plain language instruction in the chat prompt asking the AI to send an SMS to a specific phone number. Cherry Studio will call the Send SMS tool and process the request (Figure 6).
Send an SMS to +36301234567, the message should be "Hello from Cherry Studio".
You will see the result of the 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 7).
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 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 8).
Select the MCP tab to show only MCP-related activity. Here you will see the incoming tool call requests from Cherry Studio and the responses sent back, allowing you to confirm that the SMS was dispatched successfully (Figure 9).
Conclusion
You have successfully configured the Ozeki Android SMS Gateway MCP server with Cherry Studio. 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.
