Package eu.mrapik.minecraftservermcp.builtin

Class BuiltinTools

java.lang.Object

eu.mrapik.minecraftservermcp.builtin.BuiltinTools

public final class BuiltinTools
extends Object

Factory for McpToolDefinition instances used by built-in tool classes (*ToolSpec).

Implementations are anonymous classes that delegate McpToolDefinition.call(McpToolInvocation) to the supplied run function, passing both the invocation and a BuiltinToolContext (paths, settings, main-thread runner). This matches how third-party code would implement McpToolDefinition directly, except built-ins share BuiltinToolContext for common dependencies.

Method Details

define

public static McpToolDefinition define(BuiltinToolContext ctx,
 io.modelcontextprotocol.json.McpJsonMapper mapper,
 String id,
 String description,
 String inputSchemaJson,
 BiFunction<McpToolInvocation,BuiltinToolContext,reactor.core.publisher.Mono<io.modelcontextprotocol.spec.McpSchema.CallToolResult>> run)

Creates a definition with the given MCP name, description, JSON Schema string for inputs, and handler.

Parameters:

ctx - shared paths, settings supplier, and BuiltinToolContext.runSync(java.util.concurrent.Callable<io.modelcontextprotocol.spec.McpSchema.CallToolResult>) for main-thread work

mapper - JSON mapper used to parse inputSchemaJson into MCP schema objects

id - must equal access.*.tools.* keys and McpSchema.Tool.name()

description - short text for tools/list

inputSchemaJson - JSON Schema document for the tool's arguments

run - handler invoked for each call after access checks

Returns:

a new McpToolDefinition instance
