Query SMS metrics in Google ADK

Your agent fetches current marketing stats using `list_automations` and `list_keywords`. It bridges the gap between your cloud data and your SMS outreach. This allows for complex reasoning where your agent evaluates campaign success before sending follow-up messages. You get a clear view of your marketing funnel without leaving the terminal.

Sync subscriber states with MCP Server tools

The `get_subscriber` tool allows your agent to pull specific user profiles for personalized messaging. It verifies user status before triggering any automated flows. If a user updates their preferences, your agent uses `update_subscriber` to reflect those changes immediately. It keeps your data current across all platforms.

Control event streams with webhooks

Configure your event-driven architecture using `create_webhook` and `list_webhooks`. Your agent maintains control over which events trigger specific marketing actions. This setup ensures you only process relevant signals from your store. You can audit active subscriptions at any time to verify your integration health.

Setup guide

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

Common questions about Postscript MCP in Google ADK

Use the `tool_names` filter when defining your `McpToolset`. This lets you whitelist only the specific server operations your agent actually needs.

Absolutely. Since your agent can access both BigQuery and the MCP server, you can join your analytics data with live subscriber info to trigger targeted SMS campaigns.

It does. The toolset integrates with the LlmAgent, allowing Gemini to reason about your SMS marketing data and execute actions based on your business logic.

You provide the necessary environment variables to the server process. The ADK establishes a secure connection to that endpoint to execute commands.

The server uses a strict transport layer. Phone numbers and contact identifiers are only transmitted when your agent explicitly requests them to perform a specific update or lookup.
