A Bitcoin anchored public ledger of verification itself. Every record is content addressed, timestamped through OpenTimestamps, and recomputable from the raw bytes without trusting the operator. Cite a specific verification by content address, or replay the walk and see whether the live system still matches what was anchored. Read only. No account, no key.

Measures any MCP server against five published conformance conditions and returns the verdict as a recomputable record. It runs nightly against a public register, including against itself, and its own failures stay in the history where anyone can read them. No account, no key.
