Solution: How to send SMS from Kilo Code

Kilo Code is connected to the Ozeki Android SMS MCP Server through the MCP protocol, where Kilo Code 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 Kilo Code 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 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.

To use this solution you need to install the Android app on your Android phone.

Steps to follow

You will need Kilo Code installed in Visual Studio Code on your system. If you have not set it up yet, follow our Kilo Code installation guide.

  1. Install Ozeki Android SMS Gateway
  2. Enable MCP SMS Server
  3. Kilo Code SMS MCP Server Config
  4. Add the SMS MCP Server config to Kilo Code
  5. Open Kilo Code and 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 Kilo Code 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 Kilo Code in the next step.

Step 3 - Kilo Code SMS MCP Server Config

# Configuration file location:
C:\Users\%USERPROFILE%\.config\kilo\kilo.jsonc

# Add the following block inside the "mcp" property in kilo.jsonc
# Replace {address} with your Ozeki Android SMS Gateway address
"mcp": {
  "Ozeki": {
    "type": "remote",
    "url": "http://{address}:9531/mcp",
    "enabled": true,
    "timeout": 15000
  }
}

Example prompt

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

Step 4 - Add the SMS MCP Server config to Kilo Code

The following video shows how to add the Android SMS MCP server to Kilo Code step-by-step.

Navigate to the Kilo Code configuration directory at C:\Users\%USERPROFILE%\.config\kilo\ using File Explorer. Simply type %USERPROFILE%\.config\kilo into the File Explorer address bar and press Enter (Figure 1).

Navigate to Kilo Code config folder

Open the kilo.jsonc file in a text editor such as Notepad. This file stores all Kilo Code configuration, including any MCP servers (Figure 2).

Open kilo.jsonc file in text editor

Locate the mcp property in the file. If it does not exist yet, add it as a new block. Then insert the Android SMS MCP server entry as shown below. Replace {address} with the IP address shown in the Ozeki SMS Client (Figure 3). 

"mcp": {
  "Ozeki": {
    "type": "remote",
    "url": "http://{address}:9531/mcp",
    "enabled": true,
    "timeout": 15000
  }
}

Step 5 - Open Kilo Code and send a test SMS

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

Launch Visual Studio Code. Kilo Code will automatically load the updated configuration file and connect to the registered MCP servers on startup (Figure 4).

Launch VS Code
Figure 4 - Launch Visual Studio Code

Open the Kilo Code panel in Visual Studio Code and type a plain language instruction in the prompt asking the AI to send an SMS to a specific phone number. Kilo Code will call the Send SMS tool and process the request (Figure 5). 

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

Open Kilo Code and ask AI to send an SMS

You will see the result of the Send SMS tool call in the panel. A successful response confirms that the message has been passed to the Android gateway and queued for delivery (Figure 6).

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 Kilo Code 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 7).

Summary

You have successfully configured the Ozeki Android SMS Gateway MCP server with Kilo Code. 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.
