🗄 Репозиторий заархивирован

Разработка переехала в theYahia/WWmcp — монорепозиторий MCP-серверов для незападных API: СНГ, MENA, Африка, LATAM, Юго-Восточная Азия. Общее ядро @theyahia/mcp-core, единый CI, единый релизный конвейер.

Актуальная версия того, что лежало здесь: servers/tkassa/

Пакет в npm прежний — @theyahia/tkassa-mcp, ставится и работает как раньше. Здесь больше ничего не обновляется. Задачи и pull request'ы — в WWmcp.

Archived — development moved to theYahia/WWmcp, a monorepo of MCP servers for non-Western APIs. The current version of this package now lives at servers/tkassa/. The npm package @theyahia/tkassa-mcp is unchanged. Please open issues and pull requests there.

SBP - Fast Payments (2)

Receipts - 54-FZ (1)

Requires TINKOFF_INVEST_TOKEN. If not set, these tools return a descriptive error.

Auth

Every request is signed with SHA-256:

Token = SHA-256(concat(sorted values of {Password, TerminalKey, ...params}))

Only scalar values participate in signing. Nested objects (Receipt, DATA) are excluded. Handled automatically.

HTTP Transport

HTTP_PORT=3000 npx @theyahia/tkassa-mcp
# or
npx @theyahia/tkassa-mcp --http 3000

Endpoints: POST /mcp (JSON-RPC), GET /health (status).

Skills

• skill-create-payment -- create a payment and get a payment URL
• skill-payment-status -- check payment status by PaymentId

Webhook Notifications

T-Kassa sends POST notifications to your notification_url (set in init_payment) when payment status changes:

{
  "TerminalKey": "your-key",
  "OrderId": "your-order-id",
  "Success": true,
  "Status": "CONFIRMED",
  "PaymentId": 123456789,
  "ErrorCode": "0",
  "Amount": 10000,
  "RebillId": 987654321,
  "CardId": 12345,
  "Pan": "430000******0777",
  "ExpDate": "1230",
  "Token": "sha256-signature"
}

Verify by computing the Token the same way (sorted values concat + SHA-256) and comparing.

Notes

• Base URL: https://securepay.tinkoff.ru/v2/
