Implementation Reference
- src/index.ts:86-161 (handler)The handler function for the 'get_hot_news' tool, which processes the tool call, fetches data from APIs for specified sources, formats it as markdown, and returns the response.this.server.setRequestHandler(CallToolRequestSchema, async (request) => { if (request.params.name !== "get_hot_news") { throw new McpError( ErrorCode.MethodNotFound, `Unknown tool: ${request.params.name}`, ); } try { const sources = request.params.arguments?.sources as number[]; if (!Array.isArray(sources) || sources.length === 0) { throw new Error("Please provide valid source IDs"); } // Fetch multiple hot lists const results = await Promise.all( sources.map(async (sourceId) => { const source = HOT_NEWS_SOURCES[sourceId]; if (!source) { return `Source ID ${sourceId} does not exist`; } try { const response = await axios.get<HotNewsResponse>( `${BASE_API_URL}/${source.name}`, ); const news = response.data; if (!news.success) { return `Failed to fetch ${source.description}: ${news.message}`; } const newsList = news.data.map( (item: HotNewsItem) => `${item.index}. [${item.title}](${item.url}) ${ item.hot ? `<small>Heat: ${item.hot}</small>` : "" }`, ); return ` ### ${news.name}:${news.subtitle} > Last updated: ${news.update_time} ${newsList.join("\n")} `; } catch (error) { return `Failed to fetch ${source.description}: ${ axios.isAxiosError(error) ? (error.response?.data.message ?? error.message) : "Unknown error" }`; } }), ); return { content: [ { type: "text", text: results.join("\n\n"), }, ], }; } catch (error) { const errorMessage = error instanceof Error ? error.message : "Unknown error"; return { content: [ { type: "text", text: `Error: ${errorMessage}`, }, ], isError: true, }; } });
- src/index.ts:67-81 (schema)The input schema definition for the 'get_hot_news' tool, specifying an array of source IDs.inputSchema: { type: "object", properties: { sources: { type: "array", description: generateSourcesDescription(), items: { type: "number", minimum: 1, maximum: getMaxSourceId(), }, }, }, required: ["sources"], },
- src/index.ts:62-83 (registration)Registration of the 'get_hot_news' tool in the ListToolsRequestSchema handler.this.server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: [ { name: "get_hot_news", description: "Get hot trending lists from various platforms", inputSchema: { type: "object", properties: { sources: { type: "array", description: generateSourcesDescription(), items: { type: "number", minimum: 1, maximum: getMaxSourceId(), }, }, }, required: ["sources"], }, }, ],
- src/config.ts:8-18 (helper)Configuration of available hot news sources used by the handler.export const HOT_NEWS_SOURCES: Record<number, HotNewsSource> = { 1: { name: "zhihuHot", description: "Zhihu Hot List (知乎热榜)" }, 2: { name: "36Ke", description: "36Kr Hot List (36氪热榜)" }, 3: { name: "baiduRD", description: "Baidu Hot Discussion (百度热点)" }, 4: { name: "bili", description: "Bilibili Hot List (B站热榜)" }, 5: { name: "wbHot", description: "Weibo Hot Search (微博热搜)" }, 6: { name: "douyinHot", description: "Douyin Hot List (抖音热点)" }, 7: { name: "huPu", description: "Hupu Hot List (虎扑热榜)" }, 8: { name: "douban", description: "Douban Hot List (豆瓣热榜)" }, 9: { name: "itNews", description: "IT News (IT新闻)" }, };
- src/config.ts:21-32 (helper)Helper function to generate the description string for sources used in the schema.export function generateSourcesDescription(): string { const sourcesList = Object.entries(HOT_NEWS_SOURCES) .map(([id, source]) => `{ID: ${id}, Platform: "${source.description}"}`) .join(",\n"); return `Available HotNews sources (ID: Platform):\n ${sourcesList}\n Example usage: - [3]: Get Baidu Hot Discussion only - [1,3,7]: Get hot lists from zhihuHot, Baidu, and huPu - [1,2,3,4]: Get hot lists from zhihuHot, 36Kr, Baidu, and Bilibili`; }
