The protocol is natively supported in WorkOS AuthKit, providing a standardized way for AI tools to log into applications.", "body_md": "My thanks to WorkOS for sponsoring DF last week to promote Auth.md, their new open protocol for AI agent registration.\n\nSign-up forms were built for humans in browsers, so how do AI agents programmatically register with services? That’s the question Auth.md aims to answer. By exposing a single, machine-readable Markdown file at your service root, AI agents can dynamically discover your OAuth Protected Resource Metadata, parse required scopes, and authenticate seamlessly.\n\nMarkdown, baby. Who’d have thunk it?\n\nWith native support in WorkOS AuthKit, you can now implement this protocol out of the box, giving AI tools a standardized, secure way to log into your application.
