We keep a directory of public remote MCP servers and re-check every one of them through the same health checker that powers our free MCP health tool. It sends a real JSON-RPC initialize handshake, follows up with tools/list where it can, and records what came back.
This post is the aggregate. Every number below comes from one snapshot run at 2026-08-04T00:45:56Z against 86 reachable public remote MCP endpoints — the servers in the directory that answered at the transport layer. Nothing here is modelled, sampled or estimated.
One caveat worth stating before the numbers rather than after: 86 endpoints is a curated set of well-known public servers, not a random sample of the ecosystem. It is biased toward servers that vendors publish and maintain. Read everything below as "what the visible, vendor-published part of the remote MCP ecosystem looks like", not "what all MCP servers look like".
