Open-source, peer-to-peer cookie and token sync pairs two Macs so agents like OpenClaw and Hermes can stay authenticated for carts, orders, and API calls.

Why it matters
Agents that can click, buy, and call private APIs are only useful if they stay authenticated. A lightweight, peer-to-peer login and token sync removes a common failure point for Mac mini agent rigs, pushing real-world automation beyond toy demos.
Matt Van Horn (@mvanhorn) introduced Agent Cookie, an open-source tool that keeps Mac-hosted AI agents logged in by syncing cookies, bearer tokens, and API keys between machines, in a thread on X. It targets setups running OpenClaw or NousResearch's Hermes on a Mac mini, where agents often lose sessions needed to shop, book, and fetch data across consumer services.
