Implementation Reference
- src/services/wiki.service.ts:166-194 (handler)Implements the core logic for fetching categories associated with a Minecraft Wiki page using the MediaWiki API (prop=categories), handles errors, formats titles, and returns JSON response.async getCategoriesForPage(title: string): Promise<string> { const response = await apiService.get<WikiResponse, Record<string, unknown>>("", { action: "query", titles: title, prop: "categories", }); const pages = response.query?.pages; if (!pages) { throw new Error(`Failed to get categories for "${title}"`); } const page = Object.values(pages)[0]; if (page.missing) { throw new Error(`Page "${title}" not found`); } if (!page.categories?.length) { return JSON.stringify({ title: formatMCPText(title), categories: [], }); } return JSON.stringify({ title: formatMCPText(title), categories: page.categories.map((cat) => formatMCPText(cat.title)), }); }
- src/types/tools.ts:110-123 (schema)Defines the MCP Tool schema including name, description, and input schema requiring a 'title' string parameter.export const GET_CATEGORIES_FOR_PAGE_MINECRAFTWIKI_TOOL: Tool = { name: "MinecraftWiki_getCategoriesForPage", description: "Get categories associated with a specific page.", inputSchema: { type: "object", properties: { title: { type: "string", description: "Title of the Minecraft Wiki page", }, }, required: ["title"], }, };
- src/server.ts:122-128 (registration)Registers the tool execution handler in the MCP server's CallToolRequestSchema, validates args with guard, and delegates to wikiService.getCategoriesForPage.case GET_CATEGORIES_FOR_PAGE_MINECRAFTWIKI_TOOL.name: { if (!isGetCategoriesForPageArgs(args)) { throw new Error("Invalid arguments for getCategoriesForPage"); } const results = await wikiService.getCategoriesForPage(args.title); return { content: [{ type: "text", text: results }] }; }
- src/server.ts:48-60 (registration)Registers the tool in the ListToolsRequestSchema response, making it discoverable by MCP clients.// Register tool handlers server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: [ SEARCH_WIKI_MINECRAFTWIKI_TOOL, GET_PAGE_SUMMARY_MINECRAFTWIKI_TOOL, GET_SECTIONS_IN_PAGE_MINECRAFTWIKI_TOOL, GET_PAGE_SECTION_MINECRAFTWIKI_TOOL, GET_PAGE_CONTENT_MINECRAFTWIKI_TOOL, RESOLVE_REDIRECT_MINECRAFTWIKI_TOOL, LIST_CATEGORY_MEMBERS_MINECRAFTWIKI_TOOL, LIST_ALL_CATEGORIES_MINECRAFTWIKI_TOOL, GET_CATEGORIES_FOR_PAGE_MINECRAFTWIKI_TOOL, ],
- src/types/guards.ts:65-72 (helper)Type guard function to validate input arguments conform to the tool's schema (requires 'title' string). Used in tool handler registration.export function isGetCategoriesForPageArgs(args: unknown): args is { title: string } { return ( typeof args === "object" && args !== null && "title" in args && typeof (args as { title: string }).title === "string" ); }
