How to Use the Mail-in-a-Box MCP in Google ADK

Q: How do I add the Mail-in-a-Box MCP Server to a Google ADK agent?

Initialize McpToolset with the Vinkius HTTP transport parameters and pass it to your LlmAgent constructor. The Gemini model will automatically discover tools like listmailusers at runtime.

Q: Can I limit which Mail-in-a-Box tools my Google ADK agent can access?

Yes. Use the optional tool name filter when defining your McpToolset to expose only specific tools like getsystemstatus while hiding password modification tools.

Q: How does Google ADK handle long-context reasoning with Mail-in-a-Box data?

Gemini can process lists of thousands of users from listmailusers within its 1M+ token window. This allows the agent to perform deep audits of your mail domains without running out of context.

Control your Mail-in-a-Box server from Gemini-powered enterprise pipelines with Google ADK.

Perplexity

Enterprise provisioning with Google ADK and Gemini

Connect your enterprise onboarding pipelines directly to your mail infrastructure. Gemini agents use `create_mail_user` to provision mailboxes for new hires based on data pulled from your Google Cloud databases. By wrapping this MCP Server in Google's `McpToolset`, your long-context Gemini models analyze employee records and generate secure passwords to execute the creation process. This integration removes the friction of manual database lookups and mailbox setup.

Dynamic mail routing and alias cleanup

Keep your mail domains clean by letting your MCP agent manage aliases based on active projects. The agent calls `list_mail_aliases` to audit current forwarders and removes inactive ones using `delete_mail_alias`. You can restrict the toolset to expose only `create_or_update_alias` if you want to prevent accidental deletions. This gives you granular control over what your Google ADK agent can modify.

Automated system health checks in Google Cloud

Monitor your mail server's performance directly from your Gemini command center. The agent runs `get_system_status` to check system health, disk usage, and DNS status across all your mail domains. Because Google ADK integrates with your cloud monitoring, you can feed these status reports into your existing logging pipelines to keep your IT team informed. No more manual terminal checks are needed to ensure your mail is flowing.

Setup guide

Set up Mail-in-a-Box 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-in-a-Box 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-in-a-Box_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Mail-in-a-Box tools via MCP.",
    tools=mcp_tools,
)
