Perplexity

Automate newsletter delivery with Google ADK

You can trigger `create_email` from your agent to push content directly to your newsletter platform. This removes the friction of manual drafting while using the reasoning capabilities of Gemini. Checking your progress is as simple as calling `get_newsletter`. The agent pulls the latest data, letting you confirm what is ready for distribution at any time.

Manage list growth within your Google ADK agent

Your agent can execute `create_subscriber` every time a new lead hits your pipeline. This keeps your records synced across your infrastructure without manual input. If a user wants to leave, `delete_subscriber` removes them instantly. You maintain compliance and list hygiene automatically as your agent manages the list lifecycle.

Audit your infrastructure using MCP Server tools

You can inspect all your automation endpoints with `list_webhooks`. This gives you visibility into how your newsletter platform talks to your other systems. Keeping track of your tags is equally straightforward with `list_tags`. Your agent can audit your entire taxonomy, ensuring your segments remain consistent across every campaign.

Setup guide

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