MCP Registry 1.8.5 adds production diagnostics and tightens publisher validation
Model Context Protocol
MCP Registry v1.8.5 adds production performance diagnostics — request arrivals and backlog, database pool and query metrics, and slow-listing logs correlated with ingress request IDs, splitting connection acquisition, query waits, row decoding and response processing. Publisher-side it pads ECDSA P-384 signatures to fixed width, records repository.id at init so renames stay resolvable, accepts GitLab repository URLs with nested subgroups, and rejects incomplete repository metadata and invalid argument types; previously stored invalid metadata may need correction when republishing.
Why it matters
Server publishers get stricter metadata validation and operators get request-level diagnostics.
