How to Use the Apptoto MCP in Google ADK

Q: How do I register the Apptoto toolset within Google ADK?

Instantiate McpToolset with your Vinkius HTTP server parameters pointing to the Apptoto MCP endpoint. Pass that toolset object into the tools list when initializing your LlmAgent.

Q: Can I restrict which Apptoto tools my Google ADK agent can access?

Yes. Use the toolnames filter parameter when setting up your McpToolset to limit exposure of individual MCP tools. For example, you can expose listbookings while hiding createevent from specific agents.

Connect Apptoto to your Google ADK enterprise agents to analyze calendar events and sync bookings with BigQuery.

Sync calendar data with Vertex AI

This Apptoto MCP Server connects Gemini's long-context window to your schedule using `list_events` and `get_event`. Your Google ADK agent pulls months of calendar history into its 1M-token context to find scheduling conflicts. By feeding this calendar data directly into Google Cloud pipelines, you run predictive scheduling models on Vertex AI. The agent maps out your busy periods and automatically writes back new slots using `create_event`.

Query Apptoto records inside Google ADK

This MCP Server exposes customer communication preferences to Gemini via `list_lists` and `get_contact`. Your enterprise agent reads these opt-in lists to ensure your automated outreach complies with local messaging rules. Because the ADK integrates with your Google Cloud IAM, you control exactly which service accounts can query these Apptoto contact files. You run clean, governed lookups without exposing raw API tokens to the LLM.

Analyze booking trends

This integration exposes client reservation history to your agent through `list_bookings` and `get_account_check`. Gemini analyzes booking behavior over time, identifying which customers regularly reschedule their appointments. You can feed these booking records directly into BigQuery to join them with your marketing data. The ADK handles the data transfer, letting your agent run SQL queries on Apptoto history to optimize your team's availability.

Setup guide

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

Common questions about Apptoto MCP in Google ADK

Instantiate `McpToolset` with your Vinkius HTTP server parameters pointing to the Apptoto MCP endpoint. Pass that toolset object into the `tools` list when initializing your `LlmAgent`.

Yes. Use the `tool_names` filter parameter when setting up your `McpToolset` to limit exposure of individual MCP tools. For example, you can expose `list_bookings` while hiding `create_event` from specific agents.

Gemini can ingest thousands of calendar entries returned by `list_events` in a single call. The ADK feeds this entire payload into the model's context, letting it spot complex booking patterns over several months.

You can run the integration using either Stdio or HTTP transports. For cloud deployments on Google Cloud Run, the streamable HTTP transport is the most reliable option.

Your Apptoto calendar events and contact lists are processed in an isolated V8 sandbox on Vinkius. No data is used to train Gemini models, and all transit between Google Cloud and the Apptoto API is encrypted via TLS 1.3.
