Record Class McpSchema.ClientCapabilities

java.lang.Object

java.lang.Record

io.modelcontextprotocol.spec.McpSchema.ClientCapabilities

Record Components:

experimental - WIP

roots - define the boundaries of where servers can operate within the filesystem, allowing them to understand which directories and files they have access to.

sampling - Provides a standardized way for servers to request LLM sampling (“completions” or “generations”) from language models via clients.

Enclosing class:

McpSchema

public static record McpSchema.ClientCapabilities(Map<String,Object> experimental, McpSchema.ClientCapabilities.RootCapabilities roots, McpSchema.ClientCapabilities.Sampling sampling)
extends Record

Clients can implement additional features to enrich connected MCP servers with additional capabilities. These capabilities can be used to extend the functionality of the server, or to provide additional information to the server about the client's capabilities.

Constructor Details

ClientCapabilities

public ClientCapabilities(Map<String,Object> experimental,
 McpSchema.ClientCapabilities.RootCapabilities roots,
 McpSchema.ClientCapabilities.Sampling sampling)

Creates an instance of a ClientCapabilities record class.

Parameters:

experimental - the value for the experimental record component

roots - the value for the roots record component

sampling - the value for the sampling record component

Method Details

builder

public static McpSchema.ClientCapabilities.Builder builder()

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.

experimental

public Map<String,Object> experimental()

Returns the value of the experimental record component.

Returns:

the value of the experimental record component

roots

public McpSchema.ClientCapabilities.RootCapabilities roots()

Returns the value of the roots record component.

Returns:

the value of the roots record component

sampling

public McpSchema.ClientCapabilities.Sampling sampling()

Returns the value of the sampling record component.

Returns:

the value of the sampling record component
