      }
    }
  }
}

Streamable HTTP Transport

For web deployments, use the --http flag or HTTP_PORT env var:

HTTP_PORT=3000 npx @theyahia/cdek-mcp --http

Endpoints:

• POST /mcp — MCP JSON-RPC
• GET /mcp — SSE stream
• DELETE /mcp — session termination
• GET /health — health check

Environment Variables

Get your API keys: CDEK Dashboard > Integration > API Keys.

Sandbox Mode

Set CDEK_SANDBOX=true to use the CDEK test environment (api.edu.cdek.ru). Production uses api.cdek.ru.

CDEK publishes a shared sandbox account for integration testing:

• Client ID: EMscd6r9JnFiQ3bLoyjJY6eM78JrJceI
• Client Secret: PjLZkKBHEiLK3YsjtNrt3TGNG0ahs3kh

⚠️ CDEK rotates this shared test account from time to time. If you get OAuth token error (HTTP 401) … invalid_client, the public pair has been rotated — request your own sandbox keys from the CDEK integration dashboard (lk.cdek.ru → Integration → API Keys).

Authentication

OAuth 2.0 Client Credentials flow, handled by the OAuthStrategy in @theyahia/mcp-core:

• Automatic token acquisition on first request
• Token caching with proactive refresh shortly before expiry
• Concurrent request deduplication (a single in-flight token refresh is shared)
• Automatic retry on 401 with token invalidation

E-commerce Stack

Pair with other russian-mcp servers for a complete e-commerce AI stack:

Part of the russian-mcp series.

Demo Prompts

1. "How much does it cost to ship a 2kg parcel from Moscow to Saint Petersburg?" Uses get_cities to find city codes, then calculate_tariff_list to compare all available tariffs.

2. "Find the nearest CDEK pickup point to Red Square" Uses get_cities to resolve the Moscow city_code, then list_delivery_points with latitude: 55.7539, longitude: 37.6208, radius_km: 5 — results are filtered to the radius and sorted by distance (each annotated with координаты and расстояние_км).

3. "Create an order to send a book from Kazan to Novosibirsk, schedule courier pickup, and print the receipt" Uses create_order, then create_courier_pickup to schedule collection, and print_receipt for the waybill.

Development

git clone https://github.com/theYahia/cdek-mcp.git
cd cdek-mcp
npm install

npm run lint        # ESLint (flat config)
npm run typecheck   # tsc --noEmit
npm run build       # emit dist/
npm test            # unit tests (vitest)
npm run test:e2e    # e2e smoke test (lists tools, no real credentials)

Run the server locally against the CDEK sandbox (api.edu.cdek.ru) — use the shared test pair from Sandbox Mode or your own sandbox keys:

CDEK_SANDBOX=true \
CDEK_CLIENT_ID=<YOUR_SANDBOX_CLIENT_ID> \
CDEK_CLIENT_SECRET=<YOUR_SANDBOX_CLIENT_SECRET> \
npm run dev
