Tool reveals 99.9% of live MCP servers aren't ready for the July 2026 spec

Roee Tsur built a scanner that probed 4,356 reachable MCP servers and found only one compliant with the upcoming 2026-07-28 spec revision. For indie developers shipping MCP-based tooling, this is an early warning: the ecosystem is almost entirely behind, and the compliance window is closing. The open-source checker gives makers a concrete way to audit their own servers before the deadline.
