Remote MCP Servers

Servers you connect to by URL — nothing to install. All 21 493 of them have a network address, which means their uptime can actually be measured: 12 658 answered our last handshake and 4 429 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.
