Implementation Reference
- src/index.ts:35-71 (registration)Registration of the MCP tool 'search_papers_by_keyword' including schema and inline handler that delegates to AminerClientserver.registerTool( "search_papers_by_keyword", { title: "Search Papers by Keyword", description: "Search academic papers by keyword", inputSchema: { keyword: z.string().describe("Search keyword"), page: z.number().min(0).default(0).describe("Page number, starting from 0"), size: z.number().min(1).max(10).default(10).describe("Number of papers per page, maximum 10"), order: z.enum(["year", "n_citation"]).optional().describe("Sort order: year (by publication year) or n_citation (by citation count)") } }, async ({ keyword, page, size, order }) => { try { const result = await aminerClient.searchByKeyword(keyword, page, size, order); const formattedResult = aminerClient.formatSearchResults(result); return { content: [{ type: "text", text: JSON.stringify(formattedResult, null, 2) }] }; } catch (error) { return { content: [{ type: "text", text: JSON.stringify({ error: "Search failed", message: error instanceof Error ? error.message : 'Unknown error' }, null, 2) }], isError: true }; } } );
