How to Use the Saysimple MCP in Google ADK

Q: Can Gemini models use Saysimple to send SMS via Google ADK?

Yes, the agent calls listchannels to identify available SMS channels. It then uses sendmessage with the correct channel ID to dispatch the text.

Q: How does Google ADK handle incoming webhooks?

The agent runs listwebhooks to inspect active endpoints. You can then configure Google Cloud Functions to process the incoming webhook payloads and trigger agent responses.

Connect Gemini models via Google ADK to Saysimple to scale enterprise messaging and customer support pipelines.

Long-context chat analysis with Google ADK

The `list_chats` tool feeds complete conversation histories directly into Gemini's million-token context window using this MCP integration. This allows the agent to analyze months of customer interactions in a single pass without losing track of details. After digesting the history, the agent uses `assign_chat` to route the conversation to the team member best equipped to handle the specific customer issue. It eliminates manual routing queues entirely.

Enterprise customer lookup via Saysimple MCP Server

The `get_contact` tool pulls detailed customer profiles into your Google Cloud agent workflow. The agent matches this data against your BigQuery data warehouse to enrich the context before responding. When a new user messages your business, the agent runs `create_contact` to register their details instantly. This keeps your CRM and your messaging platform synchronized in real time.

Automated template dispatch and validation

The `send_message` tool triggers pre-approved WhatsApp templates based on database triggers from Vertex AI. The agent formats the template variables as a JSON string to ensure clean delivery. Before sending, the agent runs `get_template` to verify that the template is active and matches the customer's preferred language. This step prevents failed delivery attempts due to outdated template definitions.

Setup guide

Set up Saysimple 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 Saysimple 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="Saysimple_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Saysimple tools via MCP.",
    tools=mcp_tools,
)

Common questions about Saysimple MCP in Google ADK

You configure the McpToolset with your Vinkius HTTP endpoint token. The Google ADK agent then handles all authentication headers behind the scenes for every API call.

Yes, the agent calls `list_channels` to identify available SMS channels. It then uses `send_message` with the correct channel ID to dispatch the text.

Pass a list of allowed tool names to your McpToolset configuration. This restricts the Gemini model to specific operations like `list_templates` while hiding administrative actions.

The agent runs `list_webhooks` to inspect active endpoints. You can then configure Google Cloud Functions to process the incoming webhook payloads and trigger agent responses.

The MCP server executes in a zero-trust, isolated sandbox environment. Your message payloads and customer phone numbers pass through temporary memory and are never cached or logged by Vinkius.
