# Twilio WhatsApp FastMCP Server 💬
This project provides a simple FastMCP server that allows sending WhatsApp messages using the Twilio API.
## Features
* 📲 Sends WhatsApp messages via Twilio.
* 🤖 Exposes a `send_whatsapp` tool for use with FastMCP clients (like AI models).
* 🔒 Loads configuration securely from a `.env` file.
* 🧪 Includes a basic test script (`/home/rj/Code/mcp-generated/twilio_test.py`) for direct Twilio API interaction.
## Setup
1. **Get the Code:**
Clone this repository or download the source files into `/home/rj/Code/mcp-generated/`.
2. **Create a Virtual Environment (Recommended){

### 2. Running the Test Script
-The `/home/rj/Code/mcp-generated/twilio_test.py` script provides a way to directly test sending a message using your Twilio credentials *without* the FastMCP server.
+The `/home/rj/Code/mcp-generated/twilio_test.py` script provides a way to directly test sending a message using your Twilio credentials *without* the FastMCP server. 🛠️
* **Modify the script:** Ensure the `to=` number in `/home/rj/Code/mcp-generated/twilio_test.py` is a WhatsApp number linked to your Twilio Sandbox (if using the Sandbox) or any valid WhatsApp number (if using a purchased Twilio number). The `from_` number should typically be your Twilio Sandbox number (`whatsapp:+14155238886`) or your purchased Twilio WhatsApp number.
* **Run the script:**
- ```bash
+ ```bash ▶️
python /home/rj/Code/mcp-generated/twilio_test.py
```
This will attempt to send a hardcoded message ("Is this working?") from the specified Twilio number to the specified recipient.

```bash 🌱
cd /home/rj/Code/mcp-generated/
python -m venv venv
source venv/bin/activate # On Windows use `venv\Scripts\activate`
```
3. **Install Dependencies:**
The necessary dependencies are listed in `/home/rj/Code/mcp-generated/whatsapp_server.py`. You can install them using pip:
```bash 📦
pip install twilio python-dotenv pydantic-settings fastmcp
```
Alternatively, if using the FastMCP framework features:
```bash
fastmcp install /home/rj/Code/mcp-generated/whatsapp_server.py
```
4. **Configure Environment Variables:**
* Sign up for a Twilio account if you don't have one.
* Get your Account SID and Auth Token from the Twilio Console.
* Set up the Twilio Sandbox for WhatsApp or configure a dedicated Twilio WhatsApp number.
* Create a file named `.env` in the project root directory (`/home/rj/Code/mcp-generated/`).
* Add your Twilio credentials and WhatsApp number to the `.env` file:
🔑
```dotenv
# /home/rj/Code/mcp-generated/.env
TWILIO_ACCOUNT_SID=ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
TWILIO_AUTH_TOKEN=your_auth_token_here
TWILIO_WHATSAPP_NUMBER=+14155238886 # Use your Twilio WhatsApp number (Sandbox or purchased)
```
* **Important:** Replace the placeholder values with your actual credentials and number. Ensure the `TWILIO_WHATSAPP_NUMBER` starts with a `+` and includes the country code (E.164 format). The `whatsapp_server.py` script will automatically add the `+` if it's missing from the `.env` file.
❗
* **Trial Account Note:** If you are using a Twilio trial account, the `TWILIO_WHATSAPP_NUMBER` will likely be the Twilio Sandbox number (`+14155238886`). You *must* enroll any recipient (`to_number`) phone numbers in your Twilio Sandbox via the Twilio console for messages to be delivered successfully. Sending to non-enrolled numbers requires upgrading your Twilio account.
## Usage
### 1. Running the FastMCP Server
To make the `send_whatsapp` tool available for remote calls (e.g., from an AI model integrated with FastMCP):
```bash ▶️
python /home/rj/Code/mcp-generated/whatsapp_server.py
```
The server will start and print the Twilio number it's configured to use. It will listen for incoming requests (by default via stdio, but FastMCP supports other transports). A FastMCP client can then call the `send_whatsapp` tool with `to_number` (including the `whatsapp:` prefix, e.g., `whatsapp:+15551234567`) and `message` arguments.
**Example Interaction (Conceptual):**
A client (like an AI 🤖) might send a request like this (format depends on the transport):
```json
{
"tool_name": "send_whatsapp",
"arguments": {
"to_number": "whatsapp:+15551234567",
"message": "Hello from the FastMCP server!"
}
}
```
The server will process this, call the Twilio API, and return a confirmation or error message.
### 2. Running the Test Script
The `/home/rj/Code/mcp-generated/twilio_test.py` script provides a way to directly test sending a message using your Twilio credentials *without* the FastMCP server. 🛠️
* **Modify the script:** Ensure the `to=` number in `/home/rj/Code/mcp-generated/twilio_test.py` is a WhatsApp number linked to your Twilio Sandbox (if using the Sandbox) or any valid WhatsApp number (if using a purchased Twilio number). The `from_` number should typically be your Twilio Sandbox number (`whatsapp:+14155238886`) or your purchased Twilio WhatsApp number.
* **Run the script:**
```bash ▶️
python /home/rj/Code/mcp-generated/twilio_test.py
```
This will attempt to send a hardcoded message ("Is this working?") from the specified Twilio number to the specified recipient.
