Record Class McpStatelessServerFeatures.SyncToolSpecification

java.lang.Object

java.lang.Record

io.modelcontextprotocol.server.McpStatelessServerFeatures.SyncToolSpecification

Record Components:

tool - The tool definition including name, description, and parameter schema

callHandler - The function that implements the tool's logic, receiving a McpSchema.CallToolRequest and returning results.

Enclosing class:

McpStatelessServerFeatures

public static record McpStatelessServerFeatures.SyncToolSpecification(McpSchema.Tool tool, BiFunction<McpTransportContext,McpSchema.CallToolRequest,McpSchema.CallToolResult> callHandler)
extends Record

Specification of a tool with its synchronous handler function. Tools are the primary way for MCP servers to expose functionality to AI models.

SyncToolSpecification

public SyncToolSpecification(McpSchema.Tool tool,
 BiFunction<McpTransportContext,McpSchema.CallToolRequest,McpSchema.CallToolResult> callHandler)

Creates an instance of a SyncToolSpecification record class.

Parameters:

tool - the value for the tool record component

callHandler - the value for the callHandler record component

Method Details

builder

public static McpStatelessServerFeatures.SyncToolSpecification.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.

tool

public McpSchema.Tool tool()

Returns the value of the tool record component.

Returns:

the value of the tool record component

callHandler

public BiFunction<McpTransportContext,McpSchema.CallToolRequest,McpSchema.CallToolResult> callHandler()

Returns the value of the callHandler record component.

Returns:

the value of the callHandler record component
