Interface Notifications

All Known Subinterfaces:

ContextNotifications

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Notifications

Emits structured MCP notifications/message logs.

This is the public logging surface. The single abstract method log(LoggingLevel, String, Object) carries all behavior; the other methods are pure delegating conveniences, so implementations (including lambdas) only implement that one method. Threshold and capability gating, plus the wire-shape construction, live in the internal implementation — never in this interface.

Method Summary

Modifier and Type	Method	Description
default void	error(String logger, @Nullable Object data)	Emits an error-level log message.
default void	info(String logger, @Nullable Object data)	Emits an info-level log message.
default void	log(LoggingLevel level, @Nullable Object data)	Emits a structured MCP log message without a logger name.
void	log(LoggingLevel level, @Nullable String logger, @Nullable Object data)	Emits a structured MCP log message.
default void	warning(String logger, @Nullable Object data)	Emits a warning-level log message.
