Setup

Local Development Setup

1. Create a virtual environment:

python -m venv venv
source venv`/bin/activate`  # On Windows: venv\Scripts\activate

2. Install dependencies:

pip install -r requirements.txt

3. Create a .env file:

cp .env.example .env

4. Update the .env file with your VoIPBin API credentials:

VOIPBIN_API_URL=https://api.voipbin.net/v1.0
VOIPBIN_API_KEY=your-api-key-here
PORT=8000

Docker Setup

1. Build and run using Docker Compose:

# Build and start the container
docker-compose up --build

# Run in detached mode
docker-compose up -d

# Stop the container
docker-compose down

2. Or build and run using Docker directly:

# Build the image
docker build -t voipbin-mcp-server .

# Run the container
docker run -d \
  -p 8000:8000 \
  -e VOIPBIN_API_KEY=your-api-key-here \
  -e VOIPBIN_API_URL=https://api.voipbin.net/v1.0 \
  voipbin-mcp-server

Running the Server

Local Development

Standard I/O Mode

python src/main.py --transport stdio

SSE Mode

python src/main.py --transport sse --port 8000

Docker

The server runs in SSE mode by default when using Docker. The container exposes port 8000 for SSE connections.

Tool Usage Examples

Creating a Call

{
  "name": "create_call",
  "arguments": {
    "body": {
      "phone_number": "+1234567890",
      "agent_id": "agent_123",
      "campaign_id": "campaign_456"
    }
  }
}

Getting Call Details

{
  "name": "get_call",
  "arguments": {
    "call_id": "call_789"
  }
}

Creating a Conference

{
  "name": "create_conference",
  "arguments": {
    "body": {
      "name": "Team Meeting",
      "participants": ["+1234567890", "+0987654321"]
    }
  }
}

Sending a Chat Message

{
  "name": "send_chat_message",
  "arguments": {
    "chat_id": "chat_123",
    "body": {
      "message": "Hello, how can I help you today?"
    }
  }
}

Tool Annotations

Each tool includes annotations that provide metadata about its behavior:

• readOnlyHint: Indicates if the tool only reads data
• destructiveHint: Indicates if the tool modifies or deletes data
• idempotentHint: Indicates if repeated calls have the same effect as a single call
• openWorldHint: Indicates if the tool operates in an open world context

Error Handling

The server includes comprehensive error handling:

• Invalid API credentials
• Network connectivity issues
• Invalid request parameters
• Rate limiting
• Server errors

Development

Adding New Tools

To add a new tool:

1. Add the tool definition in the list_tools() function
2. Implement the tool handler in the voipbin_tool() function
3. Update the documentation

Testing

Run the test suite:

python -m pytest tests/

Security

• API keys are stored securely in environment variables
• All requests are authenticated
• HTTPS is enforced for API communication
• Input validation is performed on all requests
• Docker container runs as non-root user
• Health checks ensure container is running properly
