How to Use the Japan e-Stat MCP in Google ADK

Q: Does the Google ADK framework support searching Japan e-Stat?

Absolutely. You register the searchjapanstatistics tool within your McpToolset. Your agent can then invoke it whenever it needs to find a table ID for a specific topic.

Inject Japan's national statistics into your Google ADK agents for enterprise-grade regional analysis and reporting.

Native integration for Google ADK agents

The Japan e-Stat MCP server plugs into your Google ADK environment via standard HTTP transport. It allows your agents to query national statistics without leaving your existing Google Cloud infrastructure. Use `search_japan_statistics` to map out available datasets before your agent begins its core processing. It keeps your development cycle tight and focused on the data that matters.

Query granular government datasets

Your agent uses `get_japan_stats_data` to pull specific values, time periods, and area data. This is how you move from vague market assumptions to concrete, government-verified figures. It handles the complexity of the e-Stat schema on the backend. Your code simply receives the clean, structured data it needs to power your Gemini-based reasoning.

Support for high-volume enterprise agents

The architecture supports both Stdio and HTTP, giving you flexibility in how you host your agent. You can easily restrict exposed tools using the tool_names filter to keep your agent's scope tight. This is essential when running agents that manage multiple data pipelines. You control exactly what the agent can access from the national database at any given time.

Setup guide

Set up Japan e-Stat 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 Japan e-Stat 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="Japan e-Stat_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Japan e-Stat tools via MCP.",
    tools=mcp_tools,
)

Common questions about Japan e-Stat MCP in Google ADK

Absolutely. You register the `search_japan_statistics` tool within your `McpToolset`. Your agent can then invoke it whenever it needs to find a table ID for a specific topic.

Run a search query first to get the correct table ID. Once the agent has the ID, it passes that to `get_japan_stats_data` to retrieve the actual numbers.

Yes. Since your agent runs within the ADK, you can easily pipe the results from the MCP server into BigQuery or other storage solutions for long-term analysis.

It provides a direct, low-latency bridge to official Japanese data. You avoid the maintenance of building custom scrapers for government websites.

The server acts as a clean conduit for public statistical data. All communications are restricted to your specific query parameters, ensuring no sensitive information leaves your agent's environment.
