Foundry-ML simplifies access to machine learning-ready datasets in materials science and chemistry.

• Search & Load - Find and use curated datasets with a few lines of code
• Understand - Rich schemas describe what each field means
• Cite - Automatic citation generation for publications
• Publish - Share your datasets with the community
• AI-Ready - MCP server for Claude and other AI assistants

Quick Start

pip install foundry-ml

from foundry import Foundry

# Connect
f = Foundry()

# Search
results = f.search("band gap", limit=5)

# Load
dataset = results.iloc[0].FoundryDataset
X, y = dataset.get_as_dict()['train']

# Understand
schema = dataset.get_schema()
print(schema['fields'])

# Cite
print(dataset.get_citation())

Cloud Environments

For Google Colab or remote Jupyter:

f = Foundry(no_browser=True, no_local_server=True)

CLI

foundry search "band gap"
foundry schema 10.18126/abc123
foundry --help
