类 McpServerFeatures.SyncToolSpecification

java.lang.Object

io.modelcontextprotocol.server.McpServerFeatures.SyncToolSpecification

封闭类:

McpServerFeatures

public static class McpServerFeatures.SyncToolSpecification
extends java.lang.Object

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

Example tool specification:

 McpServerFeatures.SyncToolSpecification.builder()
 		.tool(Tool.builder()
 				.name("calculator")
 				.title("Performs mathematical calculations")
 				.inputSchema(new JsonSchemaObject()
 						.required("expression")
 						.property("expression", JsonSchemaType.STRING))
 				.build()
 		.toolHandler((exchange, req) -> {
 			String expr = (String) req.arguments().get("expression");
 			return CallToolResult.builder()
                   .content(List.of(new McpSchema.TextContent("Result: " + evaluate(expr))))
                   .isError(false)
                   .build();
 		}))
      .build();

SyncToolSpecification

public SyncToolSpecification(McpSchema.Tool tool,
                             java.util.function.BiFunction<McpSyncServerExchange,java.util.Map<java.lang.String,java.lang.Object>,McpSchema.CallToolResult> call,
                             java.util.function.BiFunction<McpSyncServerExchange,McpSchema.CallToolRequest,McpSchema.CallToolResult> callHandler)

参数:

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

call - (Deprected) The function that implements the tool's logic, receiving arguments and returning results. The function's first argument is an McpSyncServerExchange upon which the server can interact with the connected

callHandler - The function that implements the tool's logic, receiving a McpSyncServerExchange and a McpSchema.CallToolRequest and returning results. The function's first argument is an McpSyncServerExchange upon which the server can interact with the client. The second arguments is a map of arguments passed to the tool.
