Package io.modelcontextprotocol.spec

Record Class McpSchema.InitializeRequest

java.lang.Object

java.lang.Record

io.modelcontextprotocol.spec.McpSchema.InitializeRequest

Record Components:

protocolVersion - The latest version of the Model Context Protocol that the client supports. The client MAY decide to support older versions as well

capabilities - The capabilities that the client supports

clientInfo - Information about the client implementation

meta - See specification for notes on _meta usage

All Implemented Interfaces:

McpSchema.Meta, McpSchema.Request

Enclosing class:

McpSchema

public static record McpSchema.InitializeRequest(String protocolVersion, McpSchema.ClientCapabilities capabilities, McpSchema.Implementation clientInfo, Map<String,Object> meta)
extends Record
implements McpSchema.Request

This request is sent from the client to the server when it first connects, asking it to begin initialization.

Parameters:

protocolVersion - the value for the protocolVersion record component

capabilities - the value for the capabilities record component

clientInfo - the value for the clientInfo record component

meta - the value for the meta record component

InitializeRequest

@Deprecated
public InitializeRequest(String protocolVersion,
 McpSchema.ClientCapabilities capabilities,
 McpSchema.Implementation clientInfo)

Deprecated.

Method Details

builder

public static McpSchema.InitializeRequest.Builder builder(String protocolVersion,
 McpSchema.ClientCapabilities capabilities,
 McpSchema.Implementation clientInfo)

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.

protocolVersion

public String protocolVersion()

Returns the value of the protocolVersion record component.

Returns:

the value of the protocolVersion record component

capabilities

public McpSchema.ClientCapabilities capabilities()

Returns the value of the capabilities record component.

Returns:

the value of the capabilities record component

clientInfo

public McpSchema.Implementation clientInfo()

Returns the value of the clientInfo record component.

Returns:

the value of the clientInfo record component

meta

public Map<String,Object> meta()

Returns the value of the meta record component.

Specified by:

meta in interface McpSchema.Meta
