Use case
The permission layer between agents and your files
Agent permissions today are binary: no files, or all of them. Crystor adds the layer in between. Files live in an encrypted vault, agents connect to a local MCP server, and each agent sees only the folders you grant it. Zero trust, in the plain sense: nothing is visible by default, and every request is checked at one door.
Answers come back as the pages that match, not the tree. Every request and every response is logged, and shutting off an agent is one click, not a reinstall.
