Agent Use Interface (AUI) – let users bring their own AI agent
As I started building AI integrations, I came to realize that for many projects, the the best agentic experience is one that simply enables the user's personal agent to take actions within your app. The existing options like MCP or A2A are quite involved and for simple apps that are already URL parameter driven, those options seem like overkill. This led me to prototype the Agent Use Interface (AUI) spec. The idea is simple: a lightweight, open spec that makes any app "agent-navigable." You drop an XML file at /agents/aui.xml that describes the URL-parameter-driven actions your app supports, like search, create, filter, etc. And that way any AI agent can read aui.xml, understand what's possible, and construct URLs on behalf of the user. That's it. No SDK. No auth flow. No API keys. Just a catalog of what your app can do, written for LLMs to understand. Is there something like this that already exists? Is the approach too simple to be useful? If your app already supports Universal Links or is otherwise URL parameter driven you could probably add support for AUI in an afternoon.

✨ AI 요약
Agent Use Interface (AUI) is a lightweight, open specification that allows applications to be navigated by AI agents. It works by providing an XML file that describes URL-parameter-driven actions an app supports, enabling any AI agent to understand and construct URLs for user actions.

중요한 이유
AUI provides a simple, open standard for making any URL parameter-driven application discoverable and actionable by AI agents without requiring SDKs or authentication.
주요 기능
- Enables AI agents to interact with applications via URL parameters.
- Uses a lightweight XML file (/agents/aui.xml) to define app capabilities.
- Supports actions like search, create, and filter through URL parameters.
- Eliminates the need for SDKs, authentication flows, or API keys.
사용 사례
- A content creator uses their personal AI assistant to automatically update their blog's metadata by providing the AI with a link to the AUI definition, allowing the AI to construct the necessary URL parameters to trigger the update action within the blogging platform.
- A project manager integrates AUI into their team's internal task management tool. This allows their AI agent to parse project updates and automatically create new tasks or assign existing ones by interacting with the tool's defined actions through URL parameters, streamlining workflow management.
- A developer building a simple note-taking application implements AUI. This enables users' AI agents to directly create new notes, search existing ones, or apply tags by simply understanding the XML file and generating the correct URLs, without needing a complex API integration.
