MCP Gateway Operator: 62,726 Indexed Servers, Only ~30% Touched in 30 Days — and the New Spec Is Wire-Incompatible Both Directions
In the HN thread on the stateless MCP spec, the operator of the Glama MCP gateway (punkpeye) gave the ecosystem's clearest migration numbers: of 62,726 indexed open-source MCP servers, only about 30% saw any activity in the last 30 days, meaning the majority will never migrate. They call the new protocol 'wire-incompatible in both directions,' so an SDK bump alone is not enough, and predict the mess creates 'a legitimate opportunity for MCP gateways to become more valuable by becoming an interoperability layer.' They also confirmed state persistence was the single largest source of bugs in their gateway. Unresolved complaints in the thread: file/image uploads still pollute context windows as base64, and date-based versioning still has a year-old open issue asking for semver.
