I run Serverdex, a directory that indexes the official Model Context Protocol (MCP) registry. That means I have a row for every published MCP server sitting in a database — so I pulled the numbers on all 61,855 of them and wrote up the state of the ecosystem. Here's what stood out.

1. The registry 100x'd in about a year

In September 2025 the registry held a few hundred servers. It has roughly doubled month over month through 2026:

  • Feb 2026: 845 new servers
  • Jul 2026: 3,465
  • Sep 2026: 9,427
  • Oct 2026: 16,876

October 2026 alone added more servers than existed in the entire first six months. If you've felt like MCP went from "interesting protocol" to "everyone is shipping one" overnight — the data agrees.

2. Remote won

MCP started as local stdio servers: you install a package and run it yourself. That is no longer the norm.

  • 60% of servers are remote-only — a hosted HTTP endpoint with nothing to install.
  • Only ~32% ship as a local package alone.
  • streamable-http is now the dominant transport, well ahead of local stdio.

The ecosystem has quietly shifted from "download and run" to "point your client at a URL." The median server is now something you connect to, not something you install.

3. How they ship

Of the ~24,000 servers with an installable package:

  • npm: 16,717
  • PyPI: 5,367
  • MCPB: 2,295
  • Docker (OCI): 1,794
  • NuGet: 175, Cargo: 129

MCP tooling is a JavaScript-first world, with Python a clear second.

4. A few giants, a long tail

There are 1.27 million combined GitHub stars across the index — but attention is brutally concentrated. 92 servers hold 1,000+ stars each, while the vast majority have none. The head is names you'd expect: Browser Use, Scrapling, Metabase, CCXT, the official GitHub MCP server.

5. Open by default

MIT is the default license of the MCP ecosystem by a wide margin (6,571 servers), with Apache-2.0 a distant second (778). The space is overwhelmingly open source.

Methodology

Numbers are from the Serverdex index of the official MCP registry, as of 15 November 2026: 61,855 published servers. Growth is by first-publication date. Languages, stars and licenses cover the servers with a resolvable public GitHub repository. "Remote-only" means a server advertises an HTTP endpoint and no installable package.

If you maintain an MCP server, it's probably already indexed; you can claim its page for free. And if you want a specific cut of the data (by category, by month, remote vs local over time), ask in the comments — happy to pull it.
