mcp-ph-sms 1.0

A Model Context Protocol (MCP) server for sending SMS via free Philippines APIs and managing local contacts.

MCP SMS Server (Philippines)

A Model Context Protocol (MCP) server that provides SMS capabilities (via a free API) and a local contacts management system.

Setup

1. Prerequisites: Python 3.10+, uv

2. Install Dependencies:

   uv sync
   # OR if managing manually:
   uv pip install mcp[cli] httpx pydantic pydantic-settings python-dotenv sqlmodel
   

3. Configure Environment:

   Obtain your API key from https://sms-api-ph.netlify.app.

   Create a .env file in the root directory:

   SMS_API_KEY=your_actual_api_key_here
   SMS_API_BASE_URL=https://sms-api-ph-gceo.onrender.com
   DB_PATH=sqlite:///data/app.db
   LOG_LEVEL=INFO
   

Running the Server

1. Manual Testing (Script)

To verify the database and API logic without the full MCP server:

uv run test_manual.py

This will create a test contact and attempt a dry-run SMS send.

2. Run via CLI (MCP)

To start the standard IO server (mainly for debugging or piping):

uv run main.py

Note: This will appear to hang as it waits for JSON-RPC input.

3. Run with MCP Inspector (Web UI)

If you have npx installed:

npx @modelcontextprotocol/inspector uv run main.py

Integration with Claude Desktop

To use this server with Claude Desktop, add the following to your config file:

Windows Config Path: %APPDATA%\Claude\claude_desktop_config.json
(Usually C:\Users\YOUR_USER\AppData\Roaming\Claude\claude_desktop_config.json)

{
  "mcpServers": {
    "sms-ph": {
      "command": "uv",
      "args": [
        "run",
        "--with", "mcp[cli]",
        "--with", "httpx",
        "--with", "pydantic",
        "--with", "pydantic-settings",
        "--with", "python-dotenv",
        "--with", "sqlmodel",
        "d:/User/path-to-your-mcp/mcp-ph-sms/main.py"
      ],
      "cwd": "d:/User/path-to-your-mcp/mcp-ph-sms",
      "env": {
        "SMS_API_KEY": "your_key_here"
      }
    }
  }
}

Alternative (if project is already synced via uv sync):

{
  "mcpServers": {
    "sms-ph": {
      "command": "d:/User/path-to-your-mcp/mcp-ph-sms/.venv/Scripts/python.exe",
      "args": [
        "run",
        "d:/User/path-to-your-mcp/mcp-ph-sms/main.py"
      ],
      "cwd": "d:/User/path-to-your-mcp/mcp-ph-sms",
      "env": {
        "SMS_API_KEY": "your_key_here"
      }
    }
  }
}

Important:

• Ensure uv is in your system PATH.
• cwd ensures uv picks up the .env and pyproject.toml from the correct directory.
• You can omit env in the JSON if you have the .env file correctly set up.
