Remote MCP Servers
Servers you connect to by URL — nothing to install. All 21 317 of them have a network address, which means their uptime can actually be measured: 17 429 answered our last handshake and 4 938 ask who you are first, most of them through a browser sign-in rather than a key. Checked every 15 minutes.

Why this list is short on names you know
Vendors publish one server each. Stripe, Notion, Figma, Slack, Linear — one entry apiece, no competing copies.
What does produce dozens of entries under one name is hosting: 75 servers sit on
clauxel.com, 66 on alpic.live, most of them someone's staging
environment that ended up in the registry. They are listed here like everything else,
with whatever status they actually have.
