bank-api

Overview

The Bank API is a comprehensive design reference project for building compliant and modern APIs, with a built-in MCP server component. It implements banking industry standards including OWASP API Security, OpenAPI specification, GDPR, CCPA compliance, and JWS/JWK standards. The MCP server uses HTTP Stream Transport and supports API Key and OAuth authentication methods, allowing AI systems to interact with banking functionality through standardized protocol interfaces.
