How to Use the Buttondown MCP in Google ADK

The server exposes createsubscriber and other management tools. You can loop these calls within your agent logic for bulk updates.

Sync newsletter data with Google ADK

Your agent connects to your account using `list_newsletters`. It maps your existing content structure into your Google Cloud pipeline. You build agents that reason over your entire history of sent emails. It brings your marketing data into the same context as your BigQuery datasets.

Manage campaigns using Google ADK

Invoke `list_emails` to audit what you have already sent. The agent parses these drafts and identifies trends in your messaging. It works inside your existing Google Cloud architecture. You maintain full control over which tools the agent can actually trigger.

Subscriber data processing with Google ADK

Use `get_subscriber` to pull individual profiles into your agent's long-context window. Gemini models process these details alongside your cloud data. This setup allows for complex segmentation tasks. You define the criteria, and the agent identifies the correct subscribers.

Setup guide

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