For agent power users
Your agent is powerful. That's the problem.
OpenClaw and Hermes read files, run commands, and accept instructions from WhatsApp, Telegram, Discord, and email. Channels that other people can write to. A tricked agent can quietly send out anything it can read, and today it can read everything.
Crystor puts your important files in an encrypted vault and gives your agent one MCP door. It asks for what it needs, gets just the pages that answer, and every access lands in a log you can read. Grants are per folder and revocable at any time.
