    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.

    I tested ten Claude Code mods: when a guard crashes, the command still runs — only three held up

    I tested ten Claude Code mods on Claude Code 2.1.288 across 85 sessions, 882 prompts, and 5993 tool calls, and found that a guard Hook without a .catch gets skipped when it throws, so the command runs anyway. Only by adding a catch that returns deny does it fail closed.

    Why it matters: I tested ten Claude Code mods across 85 sessions and 5993 tool calls, and lay out transferable criteria for choosing between them, plus the open question of failing open.
