Brief

Agent Cookie is a tool that continuously syncs laptop cookies, CLI tokens, and API keys to a Mac mini so agents such as OpenClaw and NousResearch's Hermes remain logged in. It transmits data end-to-end encrypted over a Tailscale tailnet to avoid repeated logins during actions like adding to an Amazon cart or ordering on Instacart; see agentcookie.dev.

Why it matters

Agent Cookie continuously syncs your laptop's cookies, CLI tokens, and API keys to a Mac mini so agents like OpenClaw and NousResearch's Hermes stay logged in.

Key details

  • Sync is end-to-end encrypted over your Tailscale tailnet, eliminating repeated logins when agents perform actions like adding items to Amazon or ordering on Instacart.
  • Project landing page: agentcookie.dev; created after the author repeatedly found their Mac mini agents logged out during real tasks.

Introducing Agent Cookie. 🥷🏻🍪 For anyone running @OpenClaw or @NousResearch's Hermes on a Mac mini: I kept finding my agent logged out of everything, and it sucked. So I fixed it.

"Add this to my Amazon cart." Sorry, logged out again. "Order my usual on Instacart." Nope, not logged in anymore.
The fix: your laptop's cookies, CLI tokens, and API keys sync to your Mac mini. Continuously. Encrypted end-to-end over your Tailscale tailnet. No logging in twice.
