# ARD manifest

> Category: API, Auth, MCP & Skill Discovery

An Agentic Resource Discovery manifest is a single index of everything machine-usable you publish: MCP servers, A2A agents, OpenAPI schemas, skills.

## Why it matters

One fetch tells an agent what you have, instead of nine probes of nine well-known paths.

## Pass criteria

/.well-known/ai-catalog.json declares specVersion, host and at least one entry.

## How to implement it

Goal: Publish an ARD (Agentic Resource Discovery) manifest so agents can discover your site's capabilities

/.well-known/ai-catalog.json declares specVersion, host and at least one entry.

The step-by-step implementation prompt is part of the paid tier. The free layer gives you the diagnosis, the evidence and the specification links.
