Brief

Matt Van Horn's Agent Cookie continuously syncs laptop cookies, CLI tokens, and API keys to a Mac mini over an end-to-end encrypted Tailscale tailnet to prevent agents (e.g., OpenClaw or NousResearch's Hermes) from being logged out. @EXM7777 (posted 2026-06-01) advises pairing Agent Cookie with /last30days and PrintingPress for a markedly better Hermes experience (agentcookie.dev).

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.
