AI-Powered Java/Spring Boot code review API with Alipay AI Pay support.
API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps. Routebase keeps API design, testing, mocking and documentation on one living source of truth, and this MCP server exposes that workspace to AI agents. Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Turn any public webpage into JSON with AI, save it as a live JSON API, and call it from your agent.
