quarkiverse/quarkus-mcp-server 1.13.0

on GitHub

Highlights

• Streamable HTTP: lazy SSE initialization — SSE is now initiated on demand (when Progress, logging, etc. are actually used) instead of eagerly at request start. This
  removes the need for transport hints to disable SSE for programmatically added features. (#725)
• Streamable HTTP: auto-init honors client metadata — when auto-init=true, the server now reads clientInfo and clientCapabilities from the _meta per-request fields, so auto-initialized clients can advertise their capabilities. (#796)
• Elicitation URL mode support — elicitation now supports the URL mode per MCP 2025-11-25. (#711)
• New quarkus-mcp-server-oidc extension — returns spec-compliant insufficient_scope challenges with required scopes and resource metadata URL when OIDC-protected MCP endpoints reject a request
• OptionalInt, OptionalLong, OptionalDouble support — tool methods can use Java optional primitive types. (#769)
