# CERN Open Data MCP for AI Agents AI Agent Connect

> CERN Open Data is an Connector that gives your AI agent direct access to over 66,000 particle physics datasets from the Large Hadron Collider and LEP experiments. Use it to search for research records, retrieve metadata, find analysis software, and look up technical physics terms from the official CERN glossary.

## Description

Stop manually digging through the CERN Open Data Portal's web interface to find the specific research you need. This Connector lets you talk to your agent to pull data directly into your workspace. You can ask for specific collision types, search for Higgs boson records, or find the exact software needed to reproduce a published result. It handles the heavy lifting of navigating complex categories like Exotica or heavy-ion collisions, giving you clean metadata, file URIs, and abstracts in seconds. If you're looking for the technical definitions of terms like luminosity or b-tagging, you can pull those from the official glossary too. Vinkius makes it easy to plug this into your existing setup so you can focus on the physics instead of the filing. It's a direct line to the world's largest repository of open particle physics data, turning your agent into a specialized research assistant.

## Prompt Examples

**Prompt:** 
```
I need to find some datasets from the CMS experiment that focus on dark matter.
```

**Response:** 
```
I found several dark matter datasets from the CMS experiment. These records include:

- **Simulated Dark Matter Signal** (NanoAODSIM format)
- **Missing Transverse Energy Analyses**
- **Mono-jet and Mono-photon samples**

Would you like me to pull the full metadata or file list for any of these?
```

**Prompt:** 
```
What does the term 'transverse momentum' mean in the context of particle physics?
```

**Response:** 
```
According to the CERN physics glossary, transverse momentum (pT) is a measure of the momentum of a particle perpendicular to the beam axis. It's a key parameter used to identify high-energy particles and study their decay patterns.
```

**Prompt:** 
```
Are there any software tools available for reconstructing Higgs boson events?
```

**Response:** 
```
I found several analysis frameworks and reconstruction tools for Higgs physics. Notable examples include:

- **CMSSW** (CMS Software)
- **Analysis Frameworks** for Higgs searches
- **Validation Tools** for reconstruction

I can provide more specific links or documentation for any of these.
