MCP SDK v2 maintenance
- MCP 2026-07-28 support rejects undeclared top-level inputs and advertises error envelopes, JSON Schema 2020-12, and client-visible logging.
- Public cache hints and an explicit stateless HTTP deployment align discovery and serving behavior.
- Canonical request context propagation, typed tests, Bun 1.4 packaging, synced skills, and community metadata complete the maintenance pass.
- deps: @cyanheads/mcp-ts-core ^0.10.14 → ^0.12.3; TypeScript ^6.0.3 → ^7.0.2
