Implementation Reference
- src/mcp/tools.ts:161-182 (registration)Registers the 'search_biorxiv' MCP tool with name, description, and input schema definition.{ name: 'search_biorxiv', description: 'Search bioRxiv preprint server for biology papers', inputSchema: { type: 'object', properties: { query: { type: 'string', description: 'Search query string' }, maxResults: { type: 'number', minimum: 1, maximum: 100, description: 'Maximum number of results to return' }, days: { type: 'number', description: 'Number of days to search back (default: 30)' }, category: { type: 'string', description: 'Category filter (e.g., neuroscience, genomics)' } }, required: ['query'] } },
- src/mcp/schemas.ts:81-88 (schema)Zod schema definition for validating input arguments to the search_biorxiv tool.export const SearchBioRxivSchema = z .object({ query: z.string().min(1), maxResults: z.number().int().min(1).max(100).optional().default(10), days: z.number().int().min(1).max(3650).optional(), category: z.string().optional() }) .strip();
- src/mcp/handleToolCall.ts:153-168 (handler)MCP tool call handler that parses arguments using schema and delegates to BioRxivSearcher.search method.case 'search_biorxiv': { const { query, maxResults, days, category } = args; const results = await searchers.biorxiv.search(query, { maxResults, days, category }); return jsonTextResponse( `Found ${results.length} bioRxiv papers.\n\n${JSON.stringify( results.map((paper: Paper) => PaperFactory.toDict(paper)), null, 2 )}` ); }
- src/mcp/searchers.ts:45-47 (helper)Initializes and registers the BioRxivSearcher instance as searchers.biorxiv for use in tool handlers.const biorxivSearcher = new BioRxivSearcher('biorxiv'); const medrxivSearcher = new MedRxivSearcher(); const semanticSearcher = new SemanticScholarSearcher(process.env.SEMANTIC_SCHOLAR_API_KEY);
- src/platforms/BioRxivSearcher.ts:68-110 (handler)Core implementation of the search logic: constructs API request to bioRxiv based on date range and category, fetches results, parses into Paper objects.async search(query: string, options: BioRxivSearchOptions = {}): Promise<Paper[]> { try { // 计算日期范围 const days = options.days || 30; const endDate = new Date().toISOString().split('T')[0]; const startDate = new Date(Date.now() - days * 24 * 60 * 60 * 1000).toISOString().split('T')[0]; // 构建搜索URL const searchUrl = `${this.baseUrl}/${startDate}/${endDate}`; const params: Record<string, any> = { cursor: 0 }; // 添加分类过滤 if (query && query !== '*') { // 将查询转换为分类格式 const category = query.toLowerCase().replace(/\s+/g, '_'); params.category = category; } logDebug(`${this.serverType} API Request: GET ${searchUrl}`); logDebug(`${this.serverType} Request params:`, params); const response = await axios.get(searchUrl, { params, timeout: TIMEOUTS.DEFAULT, headers: { 'User-Agent': USER_AGENT } }); logDebug(`${this.serverType} API Response: ${response.status} ${response.statusText}`); const papers = this.parseSearchResponse(response.data, query, options); logDebug(`${this.serverType} Parsed ${papers.length} papers`); return papers.slice(0, options.maxResults || 10); } catch (error: any) { logDebug(`${this.serverType} Search Error:`, error.message); this.handleHttpError(error, 'search'); } }
