Most MCP usage is invisible.
Many of us (myself included!) expected MCP to take off as something like an “App Store” for agent-facing business logic. Companies publish servers, customers use them, ecosystems form, ???, profit.
That may still happen. But it’s not what’s happening now.
Today, there’s a small number of widely-used public servers - GitHub, Linear, maybe a handful others - and then a very long tail of servers with one or zero users. If you’re casually observing MCP usage, you’d be forgiven for thinking adoption is quite limited.
But inside modern organizations, it’s a different story. The use of MCP to serve internal data and workflows has exploded, with first-party servers solving proprietary problems. The protocol has become the standard for internal connectivity, not external distribution, and it isn’t visible on public registries because it isn’t meant for the public.
This is where the real activity is, and it’s far beyond what most people realize.
