Implementation Reference
- src/tools/search.ts:26-83 (handler)The main execution handler for the search_videos tool. It calls searchVideos helper, filters video results, formats them into a readable text output, handles pagination and count limits, and returns MCP-formatted content blocks.
async ({ keyword, page, count }) => { try { const searchResult = await searchVideos(keyword, page) || {} if (!searchResult.result || searchResult.result.length === 0) { return { content: [ { type: "text", text: `No videos found related to "${keyword}".`, }, ], } } // 过滤出视频结果并限制数量 const videoResults = searchResult.result .filter((item) => item.result_type === "video")?.[0] ?.data?.slice(0, count) as VideoSearchItem[] const formattedResults = videoResults .map((video, index) => { return [ `${index + 1}. "${video.title}" - ${video.author}`, ` BV ID: ${video.bvid}`, ` Views: ${video.play?.toLocaleString()}`, ` Danmaku: ${video.danmaku?.toLocaleString()}`, ` Likes: ${video.like?.toLocaleString()}`, ` Duration: ${video.duration}`, ` Published: ${formatTimestamp(video.pubdate)}`, ` Description: ${video.description?.substring(0, 100)}${video.description?.length > 100 ? "..." : ""}`, ].join("\n") }) .join("\n\n") return { content: [ { type: "text", text: [ `Search results for "${keyword}":`, formattedResults, `Found ${searchResult.numResults} related videos in total, currently showing ${videoResults.length} results from page ${page}.`, ].join("\n"), }, ], } } catch (error) { return { content: [ { type: "text", text: `Failed to search videos: ${error instanceof Error ? error.message : String(error)}`, }, ], } } } - src/tools/search.ts:10-25 (schema)Input validation schema using Zod for the search_videos tool parameters: keyword (required string), page (optional int >=1, default 1), count (optional int 1-20, default 10).
