Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@journal-search-mcpSearch for top journals on machine learning and verify their PDFs"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
journal-search-mcp
MCP Server (Node.js + TypeScript, Streamable HTTP transport) untuk pencarian dan verifikasi jurnal akademik PDF. Dipanggil oleh Claude sebagai MCP client/orchestrator. Claude tidak pernah membaca isi dokumen mentah — semua pembacaan/pemahaman konten PDF didelegasikan ke sub-agent Gemini Flash Lite yang mengembalikan JSON pendek.
Lihat specs.md (dokumen asli) untuk spesifikasi lengkap. README ini hanya ringkasan
cara menjalankan.
Instalasi
npm install
cp .env.example .env
# isi .env: TAVILY_API_KEY, GEMINI_API_KEYS, MCP_API_KEY minimalRelated MCP server: litra-paper-search-mcp
Menjalankan lokal
npm run build
npm start
# atau untuk development dengan watch mode:
npm run dev # di terminal lain: node dist/index.js setiap kali rebuildServer akan listen di http://localhost:3000 (atau MCP_PORT/PORT kalau di-set).
Cek cepat:
curl http://localhost:3000/health
curl "http://localhost:3000/test?key=ISI_MCP_API_KEY_ANDA"Endpoint MCP untuk dipasang di Claude:
http://localhost:3000/mcp?key=ISI_MCP_API_KEY_ANDAREST API (HTTP biasa)
Selain MCP, setiap tool juga bisa dipanggil lewat REST endpoint HTTP biasa — berguna untuk integrasi dengan backend non-MCP, Postman, curl, atau agent yang ingin akses JSON langsung tanpa protokol MCP.
Autentikasi
Sama seperti MCP endpoint: API key dikirim lewat query string ?key=....
POST /api/verify-pdf?key=ISI_MCP_API_KEY_ANDAKalau key salah atau tidak ada → 401 { "error": "invalid_or_missing_api_key" }.
Daftar endpoint
Method | Path | Deskripsi |
POST |
| Pencarian web umum (Tavily Search) |
POST |
| Ekstraksi konten halaman web |
POST |
| Crawl/jelajahi situs |
POST |
| Verifikasi magic bytes PDF dari URL |
POST |
| Analisis jurnal standar (worker round-robin) |

| Tool komposit: search → verify → judge |
GET |
| Daftar semua tool yang tersedia (metadata) |
Semua endpoint POST menerima Content-Type: application/json. Input body
mengikuti schema yang sama dengan tool MCP — lihat src/schemas/toolSchemas.ts.
Contoh request
# Verifikasi PDF
curl -X POST "http://localhost:3000/api/verify-pdf?key=ISI_MCP_API_KEY_ANDA" \
-H "Content-Type: application/json" \
-d '{"url": "https://example.com/paper.pdf"}'Response sukses (200):
{
"url": "https://example.com/paper.pdf",
"is_pdf": true,
"detected_signature": "%PDF-",
"http_status": 200
}Response validasi gagal (400):
{
"error": "invalid_input",
"error_detail": "url: url harus valid"
}Response tanpa/ salah API key (401):
{
"error": "invalid_or_missing_api_key"
}Discovery
curl "http://localhost:3000/api/tools?key=ISI_MCP_API_KEY_ANDA"Mengembalikan daftar 7 tool dengan nama, method HTTP, dan path masing-masing.
Tools yang tersedia
Tool | Deskripsi |
| Pass-through pencarian web umum |
| Pass-through ekstraksi konten halaman web |
| Pass-through crawl situs |
| Cek magic bytes URL — benar PDF atau bukan |
| verify → extract → judge (worker gemini-1/2 round-robin) |
| Sama seperti standard, tapi worker gemini-3 + custom prompt opsional |
| Tool komposit utama: search → verify → judge, banyak kandidat sekaligus |
Error handling
Semua tool tidak pernah throw ke MCP client — setiap kegagalan (download gagal,
bukan PDF, semua API key rate limited, JSON tidak valid dari Gemini, dll) dibungkus
jadi field error / error_detail pada JSON output. Lihat kode error lengkap di
src/types.ts (ToolErrorCode) dan §11 specs.md.
Level HTTP (di luar tool JSON):
401 invalid_or_missing_api_key500 server_misconfigured_missing_mcp_api_key400 invalid_json_body404 not_found
Testing
npm run typecheckLihat §12 specs.md untuk testing plan lengkap (unit test rate limiter, key pool,
magic bytes checker, integration test dengan PDF publik, dll — belum di-generate
otomatis di sini, tulis sesuai kebutuhan Anda dengan test runner pilihan, mis. vitest).
Deploy ke Render
Lihat render.yaml (infra-as-code) dan §14 specs.md. Ringkas:
Type: Web Service
Build:
npm install && npm run buildStart:
node dist/index.jsHealth check path:
/healthPORTotomatis di-inject Render — jangan hardcode port lain.Set semua secret (
TAVILY_API_KEY,GEMINI_API_KEYS,MCP_API_KEY) manual lewat Render Dashboard → Environment (jangan commit ke repo).
Non-goals fase ini
Worker 4 (Lightpanda/browser-rendering) — slot sudah disiapkan di
workerPool.ts, tapi memanggilnya akan return errornot_implemented.Caching hasil analisis.
OCR untuk PDF hasil scan.
Multi-user auth (hanya satu shared
MCP_API_KEY).
