Anonymous health checks on 78 registry MCP servers: 51.3% complete the full call sequence
Pennyforge ran anonymous health checks on the 78 servers that responded to initialize out of 186 endpoints in the a–b slice of a public MCP registry. Only 40 of them (51.3%) made it through the full flow of initialize → tools/list → one safe tools/call.
Why it matters: Anonymous health checks on 78 registry MCP servers, with reproducible data on tiered authentication and spec version migration.
