How to use the Android MCP SMS Server in Msty Claw

This guide explains how to connect the Ozeki Android SMS Gateway MCP server to Msty Claw, enabling the AI assistant to send 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 Msty Claw, and verify that everything is working by sending a test message.

Solution: How to send SMS from Msty Claw

Msty Claw is connected to the Ozeki Android SMS MCP Server through the MCP protocol, where Msty Claw 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 Msty Claw 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 Msty Claw?

Msty Claw is an AI chat application that allows you to interact with local and cloud-based large language models through a clean desktop interface. It supports MCP tool servers, enabling it to be extended with external 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.

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 Msty Claw 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 approve 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 Msty Claw in the next step.
