How to Use the Google Calendar MCP in Google ADK

Q: Can I filter which Google Calendar tools are exposed to my Google ADK agent?

Lock this down easily. Use the toolnames filter in the McpToolset configuration to restrict access. This limits your Google ADK agent to specific operations, like listevents, while hiding destructive tools like deleteevent.

Q: Can Gemini models in Google ADK read full Google Calendar descriptions?

Yes, the getevent tool returns the complete details of any Google Calendar entry. This feeds deep context into the 1M+ token window of your Google ADK agent.

Q: How do I retrieve user calendar configurations?

The getsettings tool retrieves active locale and timezone preferences. Your agent uses this data to format dates correctly before writing any updates.

Connect Google Calendar to your Google ADK pipelines via this MCP Server to schedule, read, and manage events natively.

Perplexity

Synchronizing enterprise schedules within Google ADK.

The `list_events` tool retrieves upcoming meetings directly from Google Calendar to feed into your Google ADK agent. This allows your long-context Gemini models in Google ADK to reason over weeks of scheduled Google Calendar events in a single prompt. Combining this with `get_calendar_metadata` gives your Google ADK agent structural context about your Google Calendar hierarchy. Your agent uses this metadata to decide which Google Calendar to target for subsequent write actions in Google ADK.

Enterprise-grade event creation via Google ADK.

The `create_event` tool writes structured meeting data directly into Google Calendar from your Google ADK workflows. This tool maps fields like attendees, location, and description directly from BigQuery into Google Calendar. If you need to populate quick reminders, your Google ADK agent calls `quick_add_event` to parse unstructured text into Google Calendar via our MCP Server. This keeps your Google ADK scheduling pipelines moving fast without requiring manual payload construction.

Manage access permissions using this MCP Server.

The `list_acl` tool exposes access control lists for any Google Calendar to your Google ADK agent. This enables Google Calendar security auditing workflows directly inside your Google ADK agent pipelines. By retrieving these rules, the Google ADK agent verifies who has permission to view or edit Google Calendar events. This ensures your Google ADK scheduling automation respects organizational boundaries.

Setup guide

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