Analyze massive Constant Contact campaigns in Gemini

Gemini's million-token window is perfect for parsing years of Constant Contact history. Using the Google ADK, your agent can call `list_email_campaigns` and pull every single message you've sent. The agent uses `get_campaign_details` to grab the raw HTML and subject lines of your best-performing Constant Contact emails. By comparing this data to your BigQuery customer database, the Google ADK identifies exactly which topics drive real sales.

Sync Constant Contact lists with BigQuery via this MCP Server

Keep your cloud data warehouse in sync with your actual Constant Contact subscriber base. This MCP Server lets your Google ADK agent fetch subscriber profiles using `list_contacts` and write them directly to BigQuery. The Google ADK agent can also run `list_mailing_lists` to map your segmentation strategy directly to your backend databases. It makes it easy to target high-value customers with highly specific Constant Contact campaigns based on real-time SQL queries.

Real-time performance tracking on Google Cloud

Monitor your marketing performance without building custom dashboards. Your Google ADK agent runs `get_campaign_stats` to grab open rates, click counts, and bounce metrics directly from your Constant Contact campaigns. By calling `list_recent_campaigns`, the Google ADK agent stays updated on your latest marketing pushes. It ensures your marketing team always has the latest Constant Contact numbers ready for weekly reporting.

Setup guide

Set up Constant Contact 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 Constant Contact tools in your ADK agent.

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

# 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
