How to Use the CERN Open Data MCP in Google ADK

Q: How do I integrate CERN Open Data with Google ADK?

Use the McpToolset class to connect to the server endpoint. Your Google ADK agent will then auto-discover the available tools for querying physics data.

Q: Can I search for Higgs boson data using CERN Open Data with Google ADK?

Yes. Use the searchdatasets tool with the query string 'Higgs boson' to retrieve all relevant records.

Q: Does CERN Open Data provide statistics for Google ADK agents?

Yes, getportalstatistics gives you a breakdown of records by type and experiment. This helps your agent understand the landscape of available information.

Bring Large Hadron Collider datasets into your Google ADK agent workflows for direct analysis and research.

Targeted dataset discovery for Google ADK

Your agent can execute `search_datasets` to perform full-text queries against the entire portal. It returns metadata including event counts, which you can use to prioritize high-value records. Integrating this with your existing infrastructure is simple. The MCP Server provides the metadata, and your agent handles the logic for what to do with those records.

Physics category filtering

Use `list_categories` to see the full range of research, from Higgs boson searches to heavy-ion collisions. Your agent can then use `search_by_category` to drill down into specific physics domains. This level of granularity lets your agent focus on relevant data. It stops you from wasting cycles on irrelevant records by using the built-in subcategory parameters.

Resolve and list data files

When you have a specific DOI, use `get_record_by_doi` to find the corresponding dataset record. Follow this up with `list_record_files` to get the checksums and URIs for the actual ROOT files. This chain of tools gives your agent a direct path to the data. It moves from a simple identifier to the actionable file links required for processing.

Setup guide

Set up CERN Open Data 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 CERN Open Data 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="CERN Open Data_agent",
    model="gemini-2.0-flash",
    instruction="You have access to CERN Open Data tools via MCP.",
    tools=mcp_tools,
)

Yes. Use the `search_datasets` tool with the query string 'Higgs boson' to retrieve all relevant records.

Yes, `get_portal_statistics` gives you a breakdown of records by type and experiment. This helps your agent understand the landscape of available information.

The server provides the URIs for ROOT and EOS files through the `list_record_files` tool. Your agent can then hand these links off to your data processing jobs.

The server acts as a read-only gateway to public physics data. It never requests or stores personal identifiers, ensuring your Google ADK agent environment remains isolated from sensitive user data.
