# Eleven Incumbents Agreed on How Agents Find Tools. The Two Companies Whose Agents Actually Run Weren't There.

> ARD's technical story is a discovery layer. Its guest list is a distribution story — and for a solo founder, distribution is the part that decides whether an agent ever finds you.

## Key takeaways

- On June 17, 2026, eleven vendors — Google, Microsoft, Salesforce, ServiceNow, Snowflake, Cisco, Databricks, GitHub, GoDaddy, Hugging Face, and NVIDIA — published the Agentic Resource Discovery (ARD) draft: a way for an agent to find and verify a tool before it connects, via an `ai-catalog.json` manifest on a publisher's own domain plus registries that index those manifests.
- ARD is deliberately not an execution protocol — it complements MCP and A2A rather than replacing them, pointing an agent at a resource that it then connects to over that resource's native protocol. That technical modesty was covered when the draft landed.
- What crystallized this week is the reading of the guest list. The Information framed it as the incumbents teaming up to 'beat back' Anthropic and OpenAI — the two companies whose clients most agents actually run inside, and the two names conspicuously absent from the signatories.
- The signatories are precisely the companies that own the enterprise systems of record (Salesforce, ServiceNow, Snowflake), the largest clouds (Google, Microsoft), and the code and model hubs (GitHub, Hugging Face, NVIDIA). Owning the layer where agents discover capabilities is a positioning move over who owns the shelf.
- For founders the lesson isn't which protocol wins. It's that discovery is becoming the agent era's distribution chokepoint — the successor to search-engine SEO and app-store ranking — and the cheap, forward-compatible hedge is to publish your own `ai-catalog.json` on your own domain, stay registry-neutral, and keep your call layer standard (MCP) so you can be listed wherever the discovery layer settles.

## At a glance

| Era | Who owned discovery | How you got found | The chokepoint |
| --- | --- | --- | --- |
| Web (2000s) | Google's index | SEO — rank in the results page | The search engine |
| Mobile (2010s) | Apple / Google app stores | ASO — rank in store search | The store gatekeeper |
| Agent (2026–) | Whoever owns the registry an agent queries | Be in the catalog the agent trusts | The discovery registry |
| The ARD bet | 11 incumbents' shared catalog format | Publish ai-catalog.json, get crawled | Whose registry the agent defaults to |

## By the numbers

- **June 17, 2026** — ARD draft published under Apache 2.0, built on the Linux Foundation AI Catalog data model
- **11** — launch contributors — Anthropic and OpenAI not among them
- **~97M** — monthly MCP SDK downloads by March 2026 (the layer ARD sits in front of, not against)
- **~10,000** — active public MCP servers in the registry by mid-2026
- **0** — model labs (Anthropic, OpenAI) on the ARD signatory list — the story the technical write-ups underplayed

**The short version:** [ARD](/posts/agentic-resource-discovery-ard-vs-mcp.html) — the Agentic Resource Discovery draft eleven vendors published on June 17 — is technically a modest thing: a way for an agent to *find* a tool before it connects. The story that crystallized this week is not the mechanics. It's the guest list. The eleven signatories are the companies that own the enterprise data, the clouds, and the code and model hubs. The two companies whose clients most agents actually run inside — Anthropic and OpenAI — aren't on it. If you build for the agent era, the number that should catch your eye isn't a version tag. It's the zero: zero model labs on the list.
When ARD landed, the [write-ups](/posts/agentic-resource-discovery-ard-vs-mcp.html) — this desk's included — led with what it *refuses to be*. It isn't an execution protocol. It doesn't replace [MCP](/posts/how-to-authenticate-a-remote-mcp-server.html), which by March 2026 was clearing roughly 97 million SDK downloads a month across some ten thousand public servers. ARD points an agent at a resource and steps aside; the agent connects over that resource's own protocol. A publisher drops an `ai-catalog.json` on its own domain, registries crawl it, and an agent asking "who can process a refund in euros?" gets ranked, verifiable answers. It complements MCP and [A2A](/posts/a2a-vs-acp-vs-agntcy-agent-interop-protocols.html). All true, all still true.
But "it's just a discovery layer" is exactly the sentence that let the more interesting fact sit unexamined for a month.
Read the signatories as a shelf, not a standards body
Line the eleven up by what they actually own. Salesforce holds the customer records. ServiceNow holds the workflows. Snowflake holds the data. Google and Microsoft hold the two largest clouds. GitHub and Hugging Face and NVIDIA hold the code, the models, and the silicon. These are the companies that already sit between a business and its own information — the systems of record. What they agreed on is not really a file format. It's a shared answer to the question *"when an agent goes looking for a capability, whose index does it search?"*
> The web taught us who owns discovery owns distribution. In the agent era, the index isn't a search engine — it's a registry, and eleven incumbents just proposed one they all endorse.

[The Information](https://www.theinformation.com/newsletters/applied-ai/google-microsoft-team-beat-back-anthropic-openai) put the frame bluntly: the incumbents teaming up to beat back Anthropic and OpenAI. Take the technical modesty at face value and that headline looks overheated — ARD genuinely doesn't fight MCP. But distribution power has never lived in the execution layer. It lives in the layer that decides *which* of many equivalent tools gets chosen. That's the layer ARD standardizes, and it's the layer the model labs — the ones supplying the actual agent capabilities — did not sign.
Discovery is the new SEO, and the new App Store
Every platform era has a chokepoint where being good stops being enough and being *found* takes over. In the web era it was Google's index, and a generation of companies learned to spend on SEO. In the mobile era it was the app stores, and the same companies learned app-store optimization and paid the 30% toll. The agent era's chokepoint is taking shape now, and it is the registry an agent trusts when it asks what tool to use.
If that registry consolidates into a catalog controlled by the companies that already own your customer's data, your top-of-funnel runs through a shelf you don't stock. That is the risk worth naming — not "I picked the losing protocol," but "the discovery layer fragmented into registries I have to court one by one, and the biggest one is run by a competitor."
What to actually do this week
Nothing dramatic, and nothing that bets the product. Publish an `ai-catalog.json` on your own domain today — it is nearly free, it is forward-compatible, and domain ownership doubles as cryptographic identity, so it costs you a hedge and buys you a listing wherever discovery settles. Keep MCP as your real call layer so an agent that finds you can always *use* you, on any client. And design your distribution so it never depends on a single vendor's directory to be reachable.
ARD may or may not be the standard that wins; it's a four-week-old draft the labs haven't wired into their runtimes, and a treaty is only as real as the armies that honor it. But the thing it points at — that in the agent era, whoever owns discovery owns distribution — is not a draft. That part is already load-bearing, and the guest list is the tell.

## FAQ

### What is Agentic Resource Discovery (ARD)?

A draft specification, published June 17, 2026 under Apache 2.0, for how an AI agent discovers and verifies a tool, API, skill, or other agent before connecting. A publisher hosts a machine-readable `ai-catalog.json` at a well-known path on its own domain; registries crawl those manifests and answer an agent's natural-language query with ranked, verifiable matches. It is built on the Linux Foundation AI Catalog Working Group's data model.

### Is ARD a competitor to MCP?

No — not at the protocol level. MCP defines how an agent invokes a tool; ARD defines how it finds the tool in the first place. Once ARD locates a resource, the agent connects over that resource's own protocol, which may be an MCP server, an A2A agent, or an ordinary API. ARD explicitly complements both. The competition is strategic, over whose discovery registry agents default to, not technical.

### Who backs ARD, and who doesn't?

Eleven launch contributors: Google, Microsoft, Salesforce, ServiceNow, Snowflake, Cisco, Databricks, GitHub, GoDaddy, Hugging Face, and NVIDIA. Anthropic and OpenAI — whose clients are where most agents actually run — are absent, which is the detail most of the coverage this week has fixed on.

### What should a solo founder do about it?

Treat discovery as your new top-of-funnel and hedge cheaply. Publish an `ai-catalog.json` on your own domain so any registry can index you (domain ownership doubles as identity), keep MCP as your actual call layer so you stay executable everywhere, and don't architect your distribution to depend on any single vendor's catalog. It's early to bet a product on agents finding you through ARD specifically — but the manifest is nearly free to ship and forward-compatible.

### Why does the discovery layer matter more than it sounds?

Because whoever owns the index an agent trusts decides which of many equivalent tools the agent picks — the same power Google's ranking had over web traffic and the app stores had over installs. In the agent era, being technically excellent isn't enough if the registry the agent queries never surfaces you.
