Supabase's MCP packages cut over to the v2 wire protocol today, and if you consume them, the next upgrade is not optional.

All three published MCP packages released breaking versions that move off the monolithic `@modelcontextprotocol/sdk` to the split v2 packages [1][2][3]. The peer dependency is now `@modelcontextprotocol/server`, so consumers must install the new package. Realtime also hardened its replication watchdog to restart the slot when it's not active [4], and the Studio quietly shipped a Workers list page behind a feature flag [5]. The docs team migrated 47 BigQuery-era log queries to the ClickHouse engine and retired the Logs Explorer, repointing every link at the SQL Editor [6]. If you're touching MCP integrations today, verify your package manifest before anything else. Everything else is steady motion, with 59 commits and 57 PRs across the period.
