Implementation Reference
- src/mcp/handleToolCall.ts:258-289 (handler)Main execution logic for the get_paper_by_doi tool: handles arguments, dispatches to platform searchers' getPaperByDoi method based on platform ('all' tries multiple), collects results, and returns formatted JSON response.
case 'get_paper_by_doi': { const { doi, platform } = args; const results: Record<string, any>[] = []; if (platform === 'all') { for (const [platformName, searcher] of Object.entries(searchers)) { if (platformName === 'wos' || platformName === 'scholar') continue; try { const paper = await (searcher as PaperSource).getPaperByDoi(doi); if (paper) { results.push(PaperFactory.toDict(paper)); } } catch (error) { logDebug(`Error getting paper by DOI from ${platformName}:`, error); } } } else { const searcher = (searchers as any)[platform]; if (!searcher) { throw new Error(`Unsupported platform: ${platform}`); } const paper = await searcher.getPaperByDoi(doi); if (paper) { results.push(PaperFactory.toDict(paper)); } } if (results.length === 0) { return jsonTextResponse(`No paper found with DOI: ${doi}`); } return jsonTextResponse(`Found ${results.length} paper(s) with DOI ${doi}:\n\n${JSON.stringify(results, null, 2)}`); } - src/mcp/tools.ts:298-313 (registration)Tool registration entry in the exported TOOLS array used for MCP tool advertisement, defining name, description, and JSON input schema.
