public static class McpServerFeatures.AsyncToolRegistration
extends Object

Registration of a tool with its asynchronous handler function. Tools are the primary way for MCP servers to expose functionality to AI models. Each tool represents a specific capability, such as:

• Performing calculations
• Accessing external APIs
• Querying databases
• Manipulating files
• Executing system commands

Example tool registration:

 new McpServerFeatures.AsyncToolRegistration(
     new Tool(
         "calculator",
         "Performs mathematical calculations",
         new JsonSchemaObject()
             .required("expression")
             .property("expression", JsonSchemaType.STRING)
     ),
     args -> {
         String expr = (String) args.get("expression");
         return Mono.just(new CallToolResult("Result: " + evaluate(expr)));
     }
 )
