-**A:** The annotated layer is stable for development and testing, but it depends on the official MCP Java SDK **2.0.0-M3** (a milestone release). Pin versions, run your own integration tests, and expect possible SDK API changes before 2.0 GA before relying on it in production.

+2. **MCP SDK release candidate**: This project depends on MCP Java SDK **2.0.0-RC1** (pre-release candidate). Pin versions and retest when upgrading.
 3. **ASYNC is not reactive**: `type: ASYNC` selects the async MCP server API; handlers wrap blocking Java methods in `Mono.fromCallable(...)`. Annotated methods do not return `Mono`/`Flux`.
 4. **Singleton components**: One instance per component class is shared across concurrent requests. Keep components stateless or thread-safe.
 5. **Default Required**: The default `required` value for `@McpToolParam`, `@McpPromptParam`, and `@McpJsonSchemaProperty` is `true`.
