Reliable Messaging Through the MCP Server

Need to talk to a client? You can send SMS, WhatsApp, or Viber messages using tools like `send_sms` and `send_whatsapp_message`. The Google ADK agent routes the message through Vonage's platform. This keeps your communication flow organized. Whether it’s an outbound text or a service chat, the agent handles the API call to get the job done.

Managing Identity and Webhooks with Google ADK

For secure interactions, use the verification tools. Your agent can start 2FA flow via `start_verification` and then confirm it using `check_verification_code`. You also manage inbound data by calling `update_number_webhook`, which sets the callback URL for SMS traffic. This control is key when running complex, long-context workflows that rely on accurate real-time updates.

Checking Vonage Status and Pricing with Google ADK

Before sending a blast of messages, check the books. Run `get_account_balance` to see your current credit. Need pricing info? Use `get_country_pricing` for specific countries before scheduling an SMS run. This oversight lets you build fiscally responsible agents that don't hit a budget wall mid-run.

Setup guide

Set up Vonage MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Vonage tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Vonage_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Vonage tools via MCP.",
    tools=mcp_tools,
)
