java.lang.Record

io.modelcontextprotocol.server.McpServerFeatures.AsyncPromptRegistration

Record Components:

prompt - The prompt definition including name and description

promptHandler - The function that processes prompt requests and returns formatted templates

Enclosing class:

McpServerFeatures

public static record McpServerFeatures.AsyncPromptRegistration(McpSchema.Prompt prompt, Function<McpSchema.GetPromptRequest,reactor.core.publisher.Mono<McpSchema.GetPromptResult>> promptHandler)
extends Record

Registration of a prompt template with its asynchronous handler function. Prompts provide structured templates for AI model interactions, supporting:

• Consistent message formatting
• Parameter substitution
• Context injection
• Response formatting
• Instruction templating

Example prompt registration:

 new McpServerFeatures.AsyncPromptRegistration(
     new Prompt("analyze", "Code analysis template"),
     request -> {
         String code = request.getArguments().get("code");
         return Mono.just(new GetPromptResult(
             "Analyze this code:\n\n" + code + "\n\nProvide feedback on:"
         ));
     }
 )

Constructor Details

AsyncPromptRegistration

public AsyncPromptRegistration(McpSchema.Prompt prompt,
 Function<McpSchema.GetPromptRequest,reactor.core.publisher.Mono<McpSchema.GetPromptResult>> promptHandler)

Creates an instance of a AsyncPromptRegistration record class.

Parameters:

prompt - the value for the prompt record component

promptHandler - the value for the promptHandler record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

prompt

public McpSchema.Prompt prompt()

Returns the value of the prompt record component.

Returns:

the value of the prompt record component

promptHandler

public Function<McpSchema.GetPromptRequest,reactor.core.publisher.Mono<McpSchema.GetPromptResult>> promptHandler()

Returns the value of the promptHandler record component.

Returns:

the value of the promptHandler record component
