Perplexity

Send targeted messages with `send_message`

The `send_message` tool allows your agent to push WhatsApp messages directly. Because you're working in the Gemini ecosystem, this action integrates easily into large-scale business processes. You can pair this up with `list_templates`. This lets the agent check available message templates before deployment, ensuring the content meets brand guidelines across millions of tokens.

Fetch and manage contacts using `list_contacts`

`list_contacts` pulls a directory of all WA Smart Business contacts into your workflow. When building agents on Google Cloud, knowing this list is foundational for targeted outreach. Agents can also use `get_contact` to pull deep user profiles. This data feeds directly into the long-context reasoning capabilities of Gemini models.

Audit groups and system users with `list_groups`

Use `list_groups` when you need an overview of all active WhatsApp groups managed by WA Smart Business. This visibility is critical for auditing large-scale communications. Additionally, `list_agents` helps your agent understand the support structure in place. The LlmAgent can then route messages or tasks to the correct internal team member.

Setup guide

Set up WA Smart Business 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 WA Smart Business 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="WA Smart Business_agent",
    model="gemini-2.0-flash",
    instruction="You have access to WA Smart Business tools via MCP.",
    tools=mcp_tools,
)
