What AI agents can do with CERN Open Data 16 Tools for Particle Physics
Use these tools to search, filter, and retrieve metadata for over 66,000 particle physics datasets from the LHC.
Check cern opendata status
Verify that the connection to the InvenioRDM framework is active. This ensures your queries will work correctly.
Get glossary
Retrieve definitions for physics terms like luminosity or transverse momentum. This is great for accurate science communication.
Get portal statistics
Get a high-level overview of all datasets and record types on the portal. It shows the scope of available data.
Get record by doi
Find a specific dataset using its official DOI link. This is useful when you have a reference from a publication.
Get record
Pull full metadata, abstracts, and file summaries for a specific record. Use this to see the details of a search result.
List categories
See all research categories like Higgs physics or Exotica. It shows the total dataset counts for each topic.
List experiments
View the list of experiments and their total dataset counts. Use this to see which collaborations have the most data.
List record files
Get the file names, sizes, and URIs for a specific dataset. This helps you see what's inside a record before downloading.
Search by category
Filter the repository by specific research topics and subcategories. It lets you drill down into specific physics areas.
Search by collision energy
Find data based on specific TeV or GeV energy levels. This is a primary way to scope LHC Run data.
Search by collision type
Filter results by collision types like proton-proton or lead-lead. Use this to focus on specific topologies.
Search by experiment
Scope your search to a specific collaboration like CMS or ATLAS. This is the fastest way to filter by organization.
Search datasets
Run a full-text search across all records with multiple filters. This is your primary tool for finding specific data.
Search documentation
Find guides and policies for using specific datasets. This helps you understand the data processing workflows.
Search software
Locate analysis frameworks and reconstruction tools. Use this to find software like CMSSW for your research.
Search supplementaries
Find technical configuration files needed to reproduce results. These are essential for extending published analyses.
A Connector is a URL. Vinkius runs it: hosting, security, governance, observability.
You're looking at one of 5,800+ managed Connectors. The real value isn't the catalog. It's the control plane that secures, governs, audits, and manages every interaction between your agents and the tools they use.
No Shadow AI
Every agent action is visible, approved, and auditable. Nothing runs outside your governance.
Absolute agent control
Fine-grained permissions for every agent, MCP, and tool. Instantly revoke access and audit every execution.
Cost control per token
Spend broken down to the token, tool, and agent. Budgets and hard limits. No surprise invoices.
Managed & monitored infra
We operate the runtime, authentication, scaling, retries, and monitoring. Your team manages AI, not infrastructure.
Data protection, DLP by design
Sensitive data is filtered before reaching the model. Access is governed so agents receive only the information they're allowed to use.
Token optimization, real savings
Lower AI costs by delivering the right context instead of unnecessary tools. Better accuracy, faster responses, and fewer wasted tokens.
CERN Open Data MCP for Particle Physics Research
This is for researchers and data scientists who need to move past the web interface and get straight to the data records.
Particle Physicist
Finds specific reconstruction configurations and collision datasets for new research papers without clicking through dozens of web pages.
Data Scientist
Identifies labeled physics datasets for training machine learning models for anomaly detection or particle identification.

Frequently Asked Questions
How can I find Higgs boson data with CERN Open Data? +
You can ask your agent to search by category or experiment. It will scan the 66,000+ available records and return a list of relevant datasets, including metadata like event counts and file sizes.
Does CERN Open Data help me find research software? +
Yes, you can search for specific analysis frameworks, reconstruction tools, and validation software. It provides titles, descriptions, and direct links to the software used in published results.
Can CERN Open Data include the physics glossary? +
Yes, it includes over 1,000 glossary entries. Your agent can pull definitions for technical terms like luminosity, b-tagging, and various detector components.
How do I get the files for a specific DOI? +
You can simply provide the DOI to your agent. It will resolve the DOI to the correct CERN Open Data record and provide you with the file distribution summary and URIs.
Can I see how many datasets are in the CMS experiment? +
Yes, your agent can pull portal statistics to show you the total count of datasets for CMS, along with other experiments like ATLAS and ALICE.
Is there a way to find data for specific collision energies? +
You can filter searches by specific energy levels, such as 13 TeV or 7 TeV. This helps you quickly isolate data from specific LHC runs.
Do I need an API key to use this server? +
No. The CERN Open Data Portal API is completely public and requires no authentication. Simply subscribe to this server and enter any placeholder value in the API key field to start querying particle physics datasets immediately.
What kind of data can I access from CERN? +
You can access over 66,000 datasets from major LHC experiments (CMS, ATLAS, ALICE, LHCb) and legacy experiments (DELPHI, OPERA). This includes real collision data, Monte Carlo simulations, derived datasets, analysis software, physics glossary entries, and detailed documentation. Data covers Higgs boson searches, Dark Matter studies, exotic particle searches, heavy-ion physics, and more.
Can I use CERN data for machine learning projects? +
Absolutely. CERN provides labeled datasets specifically designed for ML applications, including particle identification, jet classification, event reconstruction, and anomaly detection. Use the search tools with queries like 'machine learning' or filter by file type 'csv' or 'nanoaodsim' to find ML-ready formats. The CMS experiment alone has published thousands of simulated datasets with known physics labels.
