How to Use the MoonMail MCP in Google ADK

Q: How do I restrict which MoonMail tools are exposed to Google ADK?

You can use the toolnames filter during setup. This lets you restrict the Google ADK agent so it can only run listcampaigns and getcampaignstats, blocking it from sending emails.

Connect MoonMail to your Google ADK pipelines to analyze campaign metrics and manage lists using Gemini.

Perplexity

Query list data directly inside Google ADK

Active contact lists are retrieved using the `list_subscribers` tool directly inside the Gemini long-context window. By using Google ADK, your agent can cross-reference this subscriber data with customer tables stored in BigQuery. This makes it easy to find inactive contacts across your Google ADK pipelines. You can instantly run MoonMail cleanup routines without exporting CSV files back and forth.

Generate and send campaigns using Google ADK and Gemini

The `create_campaign` tool formats your raw text into a styled email blast. With Google ADK, Gemini can draft highly personalized email bodies based on Vertex AI insights and prepare them for delivery. Once the copy is ready, the Google ADK agent uses `send_campaign` to dispatch the message. You get a fully automated pipeline from Vertex AI data insights to MoonMail inbox delivery.

Audit campaign performance via MCP Server tools

Retrieving campaign performance is done via the `get_campaign_stats` tool, which pulls delivery failures and open rates. Your Google ADK agent can feed these metrics back into your BigQuery enterprise analytics dashboard to track marketing ROI. You can also use `get_events` to monitor recipient actions in real time. This helps your Gemini models learn which MoonMail subject lines perform best.

Setup guide

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

Common questions about MoonMail MCP in Google ADK

You can use the tool_names filter during setup. This lets you restrict the Google ADK agent so it can only run `list_campaigns` and `get_campaign_stats`, blocking it from sending emails.

Yes, Gemini's long-context window easily handles large datasets. When you call `list_subscribers` through this MCP Server, the agent can process thousands of records at once.

Not directly, but your agent acts as the bridge. The Google ADK agent queries BigQuery, processes the audience segment, and then uses the MoonMail MCP Server tools like `add_subscriber` to update your lists.

You initialize the MCP connection using the Vinkius HTTP endpoint. Your Google ADK agent auto-discovers tools like `send_campaign` and executes them based on your business logic.

Your campaign metrics and recipient logs are transmitted securely via HTTPS. Vinkius executes the MCP Server in an ephemeral sandbox, ensuring your MoonMail credentials and stats are never stored or exposed to external networks.
