Manage Email Campaigns via MCP Server

The `list_templates` tool lets your agent see all available email templates. You can check if you're using the right one before sending out anything. Need to change a template? The `set_template` tool creates or updates them instantly, making sure your agents always reference current branding.

Send Emails from Google ADK

Agents can fire off emails using the `send_email` tool. This is for one-off transactional messages—think password resets or confirmations. If you're running a campaign, use `send_template`. It takes an existing template and executes the send, keeping everything organized.

Maintain Email Infrastructure

Keep your system clean with tools like `list_webhooks` and `get_webhook`. You can check if a webhook is set up correctly to catch delivery data. If something breaks, the `delete_webhook` tool lets your agent scrub old or broken endpoint configurations.

Setup guide

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