It's LIVE: MCP Registry Tracker

Hey builders,

Our updated Agent Discoverability Registry Tracker is officially live.

It's the only daily-updated, open-source map of every ChatGPT App and Claude Connector available - 1,600+ integrations, ~30,000 indexed tools, six months of unbroken daily history, every brand and every tool description in one place.

The tracker is already used by Bloomberg, The Wall Street Journal, CNBC and Modern Retail.

I just dropped the full walkthrough on YouTube with every screen, every filter, every section, in under 15 minutes.

If you're shipping into either store (or even thinking about it), watch this first. It's the fastest way to see what the agent distribution layer actually looks like right now, and how to use the data to your advantage.

Why this matters 

Six months ago the two stores had ~200 combined integrations.

Today: ~1,600. ChatGPT is up 9.7×. Claude is up 5.2×. Both curves are still steepening.

The discipline of getting your app chosen by an agent now has a measurable surface and this is the layer that measures it.

Here's what's inside. 

1. The dashboard

Live counts of every ChatGPT App and Claude Connector, plus the daily growth curve over the last six months. Filter by platform, date range, or both and see which integrations went live yesterday.

2. Category view

Filter by family - Data & Analytics, Productivity, Travel, Finance, Dev Tools etc. - and see who's on which platform. The fastest way to check whether your category is contested or wide-open before you build.

3. Brand pages

Every brand gets its own page with the full tool list, every tool description, and auth model - for both their ChatGPT app and Claude connector, side by side. The best way to see exactly how your competitors are building.

4. Tool explorer

~30,000 indexed tools across both stores. Fully searchable, filterable by platform and auth type. Type in a brand, a verb, or a tool name and pull every match instantly.

5. Claude organic discovery (new)

A first ever look at which Claude connectors are actually appearing for real prompts inside each category. Visibility, share of voice, and rank - the first measurement layer for prompt-time distribution.

Want the deep dive?

Alongside the launch we published the full data report.

What 1,597 integrations actually reveal about how ChatGPT and Claude are converging from opposite corners, why Claude connectors are 1.8× denser than ChatGPT apps, and what organic discovery changes for everyone shipping into these stores. → Read The State of the ChatGPT App and Claude Connector Stores
