Implementation Reference
- src/utils.ts:1010-1067 (handler)Core implementation of the tool handler: performs parallel searches across PubMed, Google Scholar, Cochrane Library, and ClinicalTrials.gov, processes results, removes duplicates, and limits to 20 results.export async function searchMedicalDatabases( query: string, ): Promise<GoogleScholarArticle[]> { console.log(`š Searching medical databases for: ${query}`); // Try multiple medical databases in parallel const searches = await Promise.allSettled([ searchPubMedArticles(query, 5), searchGoogleScholar(query), searchCochraneLibrary(query), searchClinicalTrials(query), ]); const results: GoogleScholarArticle[] = []; // Process PubMed results if (searches[0].status === "fulfilled" && searches[0].value) { searches[0].value.forEach((article) => { results.push({ title: article.title, authors: article.authors.join(", "), abstract: article.abstract, journal: article.journal, year: article.publication_date.split("-")[0], citations: "", url: `https://pubmed.ncbi.nlm.nih.gov/${article.pmid}/`, }); }); } // Process Google Scholar results if (searches[1].status === "fulfilled" && searches[1].value) { results.push(...searches[1].value); } // Process Cochrane Library results if (searches[2].status === "fulfilled" && searches[2].value) { results.push(...searches[2].value); } // Process Clinical Trials results if (searches[3].status === "fulfilled" && searches[3].value) { results.push(...searches[3].value); } // Remove duplicates based on title similarity const uniqueResults = results.filter( (article, index, self) => index === self.findIndex( (a) => a.title.toLowerCase().replace(/[^\w\s]/g, "") === article.title.toLowerCase().replace(/[^\w\s]/g, ""), ), ); return uniqueResults.slice(0, 20); // Limit to 20 results }
- src/index.ts:233-251 (registration)Registration of the 'search-medical-databases' tool with MCP server, including description, Zod input schema, and wrapper handler that calls the core implementation.server.tool( "search-medical-databases", "Search across multiple medical databases (PubMed, Google Scholar, Cochrane, ClinicalTrials.gov) for comprehensive results", { query: z .string() .describe( "Medical topic or condition to search for across multiple databases", ), }, async ({ query }) => { try { const articles = await searchMedicalDatabases(query); return formatMedicalDatabasesSearch(articles, query); } catch (error: any) { return createErrorResponse("searching medical databases", error); } }, );
- src/index.ts:237-242 (schema)Zod input schema for the tool: single string parameter 'query'.query: z .string() .describe( "Medical topic or condition to search for across multiple databases", ), },
- src/utils.ts:581-605 (helper)Helper function to format and enrich the search results with safety warnings and source information before returning as MCP response.export function formatMedicalDatabasesSearch(articles: any[], query: string) { if (articles.length === 0) { return createMCPResponse( `No medical articles found for "${query}" across any databases. This could be due to no results matching your query, database API rate limiting, or network connectivity issues.`, ); } let result = `**Comprehensive Medical Database Search: "${query}"**\n\n`; result += `Found ${articles.length} article(s) across multiple databases\n\n`; articles.forEach((article, index) => { result += formatArticleItem(article, index); }); result += `\nšØ **CRITICAL SAFETY WARNING:**\n`; result += `This comprehensive search retrieves information from multiple medical databases dynamically.\n\n`; result += `**DYNAMIC DATA SOURCES:**\n`; result += `ā¢ PubMed (National Library of Medicine)\n`; result += `ā¢ Google Scholar (Academic search)\n`; result += `ā¢ Cochrane Library (Systematic reviews)\n`; result += `ā¢ ClinicalTrials.gov (Clinical trials)\n`; result = addDataNote(result); return createMCPResponse(result); }
- src/types.ts:59-90 (helper)Type definition used for the unified article format returned by the handler and helpers.export type GoogleScholarArticle = { title: string; authors?: string; abstract?: string; journal?: string; year?: string; citations?: string; url?: string; pdf_url?: string; related_articles?: string[]; }; export type ClinicalGuideline = { title: string; organization: string; year: string; url: string; description?: string; category?: string; evidence_level?: string; }; export type DrugInteraction = { drug1: string; drug2: string; severity: "Minor" | "Moderate" | "Major" | "Contraindicated"; description: string; clinical_effects: string; management: string; evidence_level: string; };
