NthFold turns codebases, spreadsheets, and OKF bundles into portable .mind files your AI can query in under a second. We’re building toward support for every major file format so your model can find what it needs wherever it lives.
Why NthFold
NthFold is not a knowledge graph.
It's a book of them. An atlas built for structured data. Before your assistant opens a file, it can ask where anything is, and find the relevant source locations down to file and line number.
Under one second
NthFold query time
Your AI spends more time thinking than querying.
How it works
From repository to query.
Connect your assistant
Create an API key in the dashboard, then install the NthFold MCP client for your editor or agent.
Snap a repository
Give your assistant a repo URL. NthFold extracts symbols and relationships into a .mind database you can download.
Ask about the structure
Your assistant translates questions into MindQL and uses the results to find relevant symbols and source locations.
Your data
Keep a copy of
your .mind file.
The database contains structural metadata like symbols, relationships, file paths, and line numbers. Download it to back it up or share it with teammates who can query it with their own accounts.
For cloud builds, NthFold temporarily clones your repository to extract its structure and deletes the clone after the build. Cloud queries use the .mind database saved to your account.
Install
Connect over MCP.
Replace the placeholder with your dashboard API key. The installer defaults to Cursor. Use --platform to choose another client.
pip install mcp
npx @nthfoldlabs/atlas-mcp install --key sk-nthfold-YOUR_KEYnpx @nthfoldlabs/atlas-mcp list lists supported clients.
