How to Use the Notion Calendar (formerly Cron) MCP in Google ADK

Q: How do I add the Notion Calendar (formerly Cron) MCP Server to my Google ADK agent?

Install the SDK, then define a McpToolset using the Vinkius HTTP transport URL. Pass this toolset into your LlmAgent initialization block, and Gemini will automatically discover the calendar tools.

Q: Can my Google ADK agent search past events in Notion Calendar (formerly Cron)?

Yes, your agent can run listevents with specific time bounds to parse past meetings. This is ideal for generating weekly activity reports or syncing meeting logs to BigQuery.

Q: Can I restrict my agent to read-only calendar access?

Yes, you can use the toolnames filter in the McpToolset configuration. Simply exclude write tools like createevent and deleteevent to prevent the agent from modifying your calendar.

Perplexity

Expose real-time scheduling links in Google ADK

`get_scheduling_links` fetches active scheduling links directly from your Notion Calendar profile. Your Google ADK agent drops these links into emails or chat threads when clients ask for booking options. This prevents your Gemini-powered agent from hallucinating URLs or pointing users to outdated scheduling pages. The model retrieves the link dynamically, ensuring it matches the current user profile.

Check calendar blocks before executing workflows

`get_free_busy` queries the active graph overlaps to see when team members are blocked or available. Your agent runs this check to verify team schedules before kicking off automated meetings. By integrating this step into your Gemini pipelines, you prevent automated scripts from overlapping with manual blocks. The tool outputs structured busy blocks that the model parses in milliseconds.

Wipe canceled meetings with this MCP Server

`delete_event` removes canceled meetings from your calendar without requiring you to open the Notion app. Your agent triggers this tool the moment a cancellation email is processed in your Google Cloud pipeline. Using this MCP Server ensures your daily schedule stays clean and immediately frees up slots for other clients. The deletion is permanent, ensuring your availability stays accurate for future booking requests.

Setup guide

Set up Notion Calendar (formerly Cron) 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 Notion Calendar (formerly Cron) 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="Notion Calendar (formerly Cron)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Notion Calendar (formerly Cron) tools via MCP.",
    tools=mcp_tools,
)
