How to Use the Cronofy MCP in Google ADK

Q: What's the setup for Google ADK?

You'll pip install google-adk and define an McpToolset pointing to your Vinkius server URL. Pass that toolset to your LlmAgent, and it's ready to start making calls.

Perplexity

Schedule Across Your Entire Org

Use `get_free_busy` to find when your whole team is free, pulling data from their mixed Google, iCloud, and Exchange accounts. The `query_availability` tool lets your Gemini agent find the first available slot that meets complex criteria. Since Google ADK is designed for long-context reasoning, your agent can analyze availability across hundreds of people for a company-wide event. It can process the results from Cronofy and cross-reference them with data you already have in BigQuery.

Let Gemini Agents Manage Calendars

Give your Google ADK agent the power to `create_event` for project kickoffs or `delete_event` when a meeting is cancelled. Cronofy handles the connection to each user's calendar provider behind the scenes. This is perfect for building internal tools on Google Cloud. You can create an agent that listens to a Pub/Sub topic and automatically books a post-mortem meeting by calling Cronofy's `create_event` tool through this MCP Server.

Integrate Calendars into Your GCP Workflow

The `read_events` and `list_calendars` tools give your agent a full picture of a user's schedule. Cronofy unifies calendar data so your agent doesn't have to deal with three different APIs. Imagine an agent that pulls a user's upcoming meetings with `read_events`, then fetches related project documents from Google Drive. With Google ADK, you can build agents that combine Cronofy's calendar data with other Google Cloud services.

Setup guide

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

Common questions about Cronofy MCP in Google ADK

First, your Gemini agent queries BigQuery. Based on the results, it can then use the Cronofy `create_event` tool, exposed via the MCP Server, to book the meeting across the right users' calendars.

Yes, that's the point. Cronofy unifies Google Calendar, iCloud, and Microsoft Exchange. Your Google ADK agent just uses one set of tools, like `read_events`, and gets data from all of them.

Definitely. Google ADK is built for complex, long-context tasks. Your agent can monitor schedules over time, use `get_free_busy` to find complex availabilities, and manage events without losing context.

You'll `pip install google-adk` and define an `McpToolset` pointing to your Vinkius server URL. Pass that toolset to your `LlmAgent`, and it's ready to start making calls.

It processes calendar event information, user profiles, and availability data. The entire operation runs in a Vinkius zero-trust sandbox, ensuring that your agent's access to this scheduling data is contained and secure within your GCP environment.
