Streamable HTTP (remote / Docker)

⚠️ The HTTP transport exposes money-moving tools. It requires a Bearer token, binds to 127.0.0.1 by default, and validates Host/Origin (DNS-rebinding protection). Never expose it directly to the internet — put it behind an authenticating reverse proxy / mTLS. See SECURITY.md.

MCP_AUTH_TOKEN="$(openssl rand -hex 32)" HTTP_PORT=3000 npx -y @theyahia/yookassa-mcp --http

Then call /mcp with Authorization: Bearer <MCP_AUTH_TOKEN>.

Endpoints:

• POST /mcp -- MCP Streamable HTTP transport (Bearer auth required; stateless — POST only)
• GET /health -- unauthenticated health check ({ "status": "ok", "tools": <count> })

Environment Variables

Variable	Required	Description
YOOKASSA_SHOP_ID	Yes	Shop ID (Settings -> Shop)
YOOKASSA_SECRET_KEY	Yes	Secret key (Integration -> API Keys)
YOOKASSA_PAYOUT_AGENT_ID	Payouts	Gateway id (agentId) for the Payouts product (Settings -> Payouts)
YOOKASSA_PAYOUT_SECRET_KEY	Payouts	Secret key for the Payouts gateway
HTTP_PORT	No	Port for HTTP transport (default 3000); enables --http mode
MCP_AUTH_TOKEN	HTTP only	Required in HTTP mode. Bearer token clients must send on /mcp
HTTP_HOST	No	Bind address for HTTP mode (default 127.0.0.1; set 0.0.0.0 to expose — only behind a proxy)
MCP_ALLOWED_HOSTS	No	Comma-separated Host allowlist (default 127.0.0.1:<port>,localhost:<port>)
MCP_ALLOWED_ORIGINS	No	Comma-separated browser Origin CORS allowlist (default: none — browser origins rejected)
YOOKASSA_DEBUG	No	Set to 1 to trace each request (method/path/status/latency/idempotency-key) to stderr — never logs secrets, the auth header, or request bodies

Test mode / safety

This server drives real money operations. While developing:

1. Create a test shop in the YooKassa dashboard and use its YOOKASSA_SHOP_ID / YOOKASSA_SECRET_KEY.
2. Confirm you are in test mode by calling get_shop_info — expect "test": true — before switching to a live shop.
3. In a live shop, create_payment, create_refund, create_payout, create_recurring_payment, save_payment_method, and capture_payment move real funds and are irreversible. These tools are annotated as destructive so MCP clients can prompt before running them.
4. The HTTP transport is unauthenticated-by-default-refused and binds to localhost — see SECURITY.md before any remote deployment.

Tools (20)

Payments (9)

Tool	Description
create_payment	Create a payment with amount, description, payment method. Returns payment URL. Supports receipts and metadata
get_payment	Get payment details by ID -- status, amount, confirmation URL, metadata
capture_payment	Confirm a two-step payment (capture held funds). Partial capture supported
cancel_payment	Cancel a payment (pending or waiting_for_capture)
list_payments	List payments with filters by status, date range, and pagination
save_payment_method	Save a payment method for recurring charges (card binding)
create_recurring_payment	Charge a saved payment method (no user interaction)
create_sbp_payment	Create a payment via SBP (Russian fast payment system)
create_split_payment	Split payment for marketplaces -- distribute funds among partners

Refunds (3)

Tool	Description
create_refund	Full or partial refund by payment ID
get_refund	Get refund details by ID
list_refunds	List refunds with optional payment filter

Receipts (2)

Tool	Description
create_receipt	Fiscal receipt (54-FZ) -- items, VAT codes, customer contacts
list_receipts	List receipts by payment or refund ID

Payouts (2)

⚠️ Payouts are a separately-activated YooKassa product with their own gateway credentials (YOOKASSA_PAYOUT_AGENT_ID + YOOKASSA_PAYOUT_SECRET_KEY), not the shop's payment key. Sending a raw card number requires a PCI DSS certificate — without it, collect the recipient via the payout widget and pass payout_token. Payouts are asynchronous (poll get_payout).

Tool	Description
create_payout	Payout to bank card / YooMoney wallet / SBP, or via payout_token
get_payout	Get payout status and details by ID

Webhooks (3)

Tool	Description
create_webhook	Register a webhook URL for events (payment.succeeded, refund.succeeded, etc.)
list_webhooks	List all registered webhooks
delete_webhook	Delete a webhook by ID

Account (1)

Tool	Description
get_shop_info	Shop info -- ID, status, test mode, fiscalization (YooKassa has no balance endpoint)

Demo Prompts

Create a payment for 5000 RUB for order #123 with SBP as payment method

Set up a recurring subscription: bind the card with 1 ruble, then charge 999 RUB monthly using the saved method

Show all successful payments for the last 7 days and create a refund of 2500 RUB for payment pay_xxx

Architecture

• Auth: HTTP Basic Auth (YOOKASSA_SHOP_ID:YOOKASSA_SECRET_KEY)
• Base URL: https://api.yookassa.ru/v3/
• Idempotence-Key: one stable UUID v4 per logical POST/DELETE request, preserved across retries (a retried request is de-duplicated by YooKassa, never double-charged). Callers may pass an explicit key.
• Timeout: 35 seconds (above YooKassa's ~30s server-side answer window, so slow-but-successful operations are not aborted client-side)
• Retry: 3 attempts on 429/5xx/timeout with exponential backoff (1s, 2s, 4s); retries reuse the same Idempotence-Key, so they are safely de-duplicated
• Transport: stdio (default) or Streamable HTTP (--http / HTTP_PORT)
