Annotation Interface McpToolArgument

@Target(PARAMETER) @Retention(RUNTIME) public @interface McpToolArgument
Binds a parameter of an McpTool method as a published tool argument.

Requiredness is inferred from the declared parameter type: T is required and Optional<T> is optional. A blank name() uses the source-level Java parameter name. Explicit names provide a stable public contract across Java refactoring. Use McpToolProperty to supply the corresponding schema metadata for a component of an ordinary typed input or output record.
