Get started

The ARD specification is open and available now. Pick the path that fits you:

• Use it in a chatbot: Add a connector, such as GitHub's Agent Finder or Hugging Face Discover, to Claude, ChatGPT, Copilot, or Gemini so your assistant can discover tools, skills, and agents for a task — and you decide what to install.
• Publish your first catalog: Follow the publishing guide to host an ai-catalog.json file on your own domain and make your agentic resources discoverable in minutes.
• Build a client: Use the client guide to discover and invoke agentic resources at runtime, instead of hardcoding them into your agent.
• Read the specification: Dig into the ARD specification — the full data model, search and federation semantics, and the trust model.
• Get involved & give feedback: ARD is developed in the open. Browse the code and reference implementations on GitHub, and share feedback, questions, bug reports, or proposed changes through the ARD-spec issue tracker.

The agent ecosystem works best when it is decentralized and open. ARD is our contribution to keeping it that way — we'd love your feedback, and your catalog.
