How to configure the Ozeki SMS MCP Server in Cline

This guide walks you through integrating the Ozeki SMS MCP Server with Cline, a powerful AI coding assistant extension for Visual Studio Code. By following this tutorial, you will learn how to navigate to the Cline MCP Servers panel, register the Ozeki SMS Gateway as an MCP server, and confirm that the SMS tools are connected and available for use in your conversations.

What is an MCP server?

An MCP (Model Context Protocol) server exposes tools that an AI model can call during a conversation. In this setup, the Ozeki SMS MCP Server provides SMS tools such as sending messages and listing incoming SMS. Cline connects to the MCP server over HTTP using the Streamable HTTP transport and communicates with it directly using the configured URL and API key, making it straightforward to add mobile messaging capabilities to any Cline workflow.

Cline MCP server configuration

# Navigate to the following location in Cline to open the config file:
# Cline -> MCP Servers -> Configure

# Add the following block to the configuration file
# Replace {address} with your Ozeki SMS Gateway host IP or hostname
# Replace the Bearer token with the API key generated for your MCP user account
{
  "mcpServers": {
    "Ozeki": {
      "url": "http://{address}:9529/mcp",
      "type": "streamableHttp",
      "timeout": 600,
      "headers": {
        "Authorization": "Bearer abcd1234"
      }
    }
  }
}

Steps to follow

We assume Ozeki SMS Gateway is already installed on your system and you have already created an MCP user account with an API key. You will also need Cline installed in VS Code on your system. If you have not set it up yet, follow our Cline installation guide.

  1. Open Cline and navigate to MCP Servers
  2. Add Ozeki SMS MCP Server to config
  3. Save config and verify connection

  "mcpServers": {
    "Ozeki": {
      "url": "http://{address}:9529/mcp",
      "type": "streamableHttp",
      "timeout": 600,
      "headers": {
        "Authorization": "Bearer ozkey-abc123"
      }
    }
  }
}
