Tkassa Mcp

Connects Claude to T-Kassa, the T-Bank payment gateway used across Russia. You get 16 tools covering the full lifecycle: init payments with 54-FZ compliant receipts, confirm or cancel two-step transactions, process refunds, manage saved cards and recurring charges via RebillId, generate SBP QR codes for Faster Payments System transfers, and even pull T-Invest portfolio data if you pass a token. All requests are auto-signed with SHA-256. Useful when you're building checkout flows, subscription billing, or fiscal-compliant retail systems that need programmatic access to Tinkoff's payment rails without writing your own API client.
