How to Use the Mail Blaze MCP in Google ADK

Q: How do I initialize the Mail Blaze MCP Server in Google ADK?

Instantiate McpToolset with your Vinkius HTTP server parameters and pass it to your LlmAgent. Gemini will automatically detect the nine tools and execute them based on your prompts.

Q: Can I limit Gemini to specific Mail Blaze tools?

Yes, you can use the toolnames filter in the ADK setup to restrict access. For example, you can expose listsubscriberlists while hiding destructive tools like deletelistsubscriber.

Connect Gemini agents to Mail Blaze using the Google ADK to run data-driven marketing campaigns directly from BigQuery.

Sync enterprise data using Google ADK and Mail Blaze

This MCP Server exposes the `add_subscriber_to_list` tool to bridge the gap between your BigQuery warehouse and your active marketing lists. Your Gemini agent queries your database, finds new leads, and pushes them directly to Mail Blaze. You can also use `update_list_subscriber` to keep contact profiles updated as their status changes in Google Cloud. This keeps your segments fresh without manual export pipelines.

Draft campaigns from long-context research

The `create_new_campaign` tool takes structured output from Gemini's 1M+ token reasoning window and builds complete email campaigns. Your agent analyzes customer feedback trends and drafts highly relevant copy. Once the draft is ready, `send_email_campaign` fires the emails to your selected audience. This allows you to build autonomous marketing loops that react to business data in real time.

Audit subscriber lists and campaign performance

Using this MCP integration, the `list_subscriber_lists` tool lets your agent inspect all available lists to verify target segments before launching a campaign. It prevents sending emails to the wrong audience. Use `get_campaign_details` alongside `list_email_campaigns` to feed performance data back into Vertex AI. Your models can then analyze open rates and suggest layout changes for the next batch.

Setup guide

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

Common questions about Mail Blaze MCP in Google ADK

Instantiate `McpToolset` with your Vinkius HTTP server parameters and pass it to your `LlmAgent`. Gemini will automatically detect the nine tools and execute them based on your prompts.

Yes, your agent can read customer records from BigQuery and use `add_subscriber_to_list` to populate your lists. It can then trigger a send using `send_email_campaign` immediately.

Vinkius handles the underlying REST API authentication securely. Your Google ADK agent only needs the single endpoint token, removing the need to manage API keys inside your Google Cloud environment.

Yes, you can use the `tool_names` filter in the ADK setup to restrict access. For example, you can expose `list_subscriber_lists` while hiding destructive tools like `delete_list_subscriber`.

All transmission of campaign details and subscriber lists occurs over encrypted TLS connections. Vinkius runs the server in an ephemeral sandbox, meaning no personal data is stored on disk after the tool execution finishes.
