Implementation Reference
- src/server.ts:51-63 (registration)Registers the MCP 'get_feeds' tool with input schema for uid and limit, description, and a handler that calls WeiboCrawler.extractWeiboFeeds and returns JSON stringified feeds.
server.tool("get_feeds", "获取指定微博用户的最新动态和帖子", { uid: z.number().describe("微博用户的唯一标识符"), limit: z.number().describe("返回的最大动态数量") }, async ({ uid, limit }) => { const feeds = await crawler.extractWeiboFeeds(uid, limit); return { content: [{ type: "text", text: JSON.stringify(feeds) }] }; } ); - src/weibo.ts:35-60 (handler)Core handler implementing the tool logic: fetches user's Weibo feeds by obtaining containerId from profile, then iteratively fetches pages of feeds until the limit is reached or no more available.
async extractWeiboFeeds(uid: number, limit: number): Promise<Record<string, any>[]> { const feeds: Record<string, any>[] = []; let sinceId = ''; try { const containerId = await this.getContainerId(uid); if (!containerId) return feeds; while (feeds.length < limit) { const pagedFeeds = await this.extractFeeds(uid, containerId, sinceId); if (!pagedFeeds.Feeds || pagedFeeds.Feeds.length === 0) { break; } feeds.push(...pagedFeeds.Feeds); sinceId = pagedFeeds.SinceId as string; if (!sinceId) { break; } } } catch (error) { console.error(`无法获取UID为'${uid}'的动态`, error); } return feeds.slice(0, limit); } - src/weibo.ts:118-137 (helper)Helper method to extract the containerId for a user's feeds from their profile API response.
private async getContainerId(uid: number): Promise<string | null> { try { const response = await axios.get(PROFILE_URL.replace('{userId}', uid.toString()), { headers: DEFAULT_HEADERS }); const data = response.data; const tabsInfo = data?.data?.tabsInfo?.tabs || []; for (const tab of tabsInfo) { if (tab.tabKey === 'weibo') { return tab.containerid; } } return null; } catch (error) { console.error(`无法获取UID为'${uid}'的containerId`, error); return null; } } - src/weibo.ts:147-169 (helper)Helper method to fetch a single page of user feeds using the feeds API URL constructed with containerId and sinceId, returning PagedFeeds structure.
private async extractFeeds(uid: number, containerId: string, sinceId: string): Promise<PagedFeeds> { try { const url = FEEDS_URL .replace('{userId}', uid.toString()) .replace('{containerId}', containerId) .replace('{sinceId}', sinceId); const response = await axios.get(url, { headers: DEFAULT_HEADERS }); const data = response.data; const newSinceId = data?.data?.cardlistInfo?.since_id || ''; const cards = data?.data?.cards || []; if (cards.length > 0) { return { SinceId: newSinceId, Feeds: cards }; } else { return { SinceId: newSinceId, Feeds: [] }; } } catch (error) { console.error(`无法获取UID为'${uid}'的动态`, error); return { SinceId: null, Feeds: [] }; } } - src/server.ts:53-56 (schema)Zod input schema defining parameters for the get_feeds tool: uid (number) and limit (number).
