An MCP server that enables AI agents to perform cryptocurrency payments through the Bitnovo Pay API. It provides capabilities to create payments (direct on-chain via create_payment_onchain and web-based via create_payment_link), retrieve payment status, and generate high-quality QR codes, while giving access to a currencies catalog. The server exposes eight MCP tools: create_payment_onchain, create_payment_link, get_payment_status, list_currencies_catalog, generate_payment_qr, get_webhook_events, get_webhook_url, and get_tunnel_status. It supports automatic webhook delivery through three tunnel providers (ngrok, zrok, manual) to expose webhook endpoints for real-time notifications. It is designed for multi-LLM environments including OpenAI ChatGPT, Google Gemini, and Claude. QR outputs are high quality (512px default, up to 2000px) with branding and interpolation optimizations. The architecture is stateless, with privacy-by-default data masking, HTTPS enforcement, HMAC validation, and nonce-based replay protection. Reliability is enhanced with built-in retry and timeout handling. Deployment is flexible, including cloud options (Railway) and Docker-based setups, with environment variable configuration (BITNOVO_DEVICE_ID, BITNOVO_BASE_URL, BITNOVO_DEVICE_SECRET). Prerequisites include Node.js 18+ and a Bitnovo Pay account.
