How to Use the Calendarific Alternative MCP in Google ADK

Q: How do I register Calendarific Alternative inside my google-adk pipeline?

Initialize the toolset using McpToolset with your Vinkius MCP Server HTTP endpoint parameters. Pass this toolset into the tools list when constructing your LlmAgent.

Q: Can I restrict which Calendarific Alternative tools are exposed to google-adk?

Yes, you can. Use the toolnames parameter in your ADK setup to expose only getholidays or listsupportedcountries based on what your agent needs.

Feed global holiday data directly to your Google ADK agents to align BigQuery datasets with regional calendars.

BigQuery Data Alignment via Google ADK

The `get_holidays` tool pulls localized holiday schedules directly into your Google ADK workflows to filter transactional data. Your agents run queries on BigQuery, cross-referencing transaction spikes against regional public holidays. You initialize this tool using `McpToolset` and pass it to your `LlmAgent`. Gemini models use their massive context window to analyze years of holiday trends alongside your warehouse data.

Regional Filtering with Google ADK MCP Server Tools

The `list_supported_countries` tool provides your Google ADK agent with a clean list of supported regions before executing batch data pipelines. This keeps your pipeline logic clean by filtering out unsupported countries early. By passing `StreamableHttpServerParameters` to your toolset, your agent quickly queries the endpoint. You can also use the `tool_names` filter if you only want to expose country validation to specific LlmAgent instances.

Long-Context Holiday Analysis

The `get_holidays` tool injects global holiday schedules into Gemini's million-token context window. This allows your agent to construct complex, multi-year business forecasts across dozens of countries simultaneously. Your agent handles the HTTP transport natively through the ADK toolset. This setup ensures that your enterprise pipelines remain fully integrated with Google Cloud infrastructure without custom API wrappers.

Setup guide

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