Keryx – One TypeScript action class, five transports (HTTP, WS, CLI, MCP, tasks)

17 hours ago

MCP-Native allows every action to automatically function as an MCP tool with built-in OAuth 2.1 authentication and typed errors.
A single action class can serve multiple purposes: HTTP endpoint, CLI command, WebSocket handler, and background task runner.
Keryx framework unifies various transports (HTTP, WebSocket, CLI, background tasks, MCP) with the same validation and error handling.
Example actions like 'Status' and 'UserCreate' demonstrate how one class can handle different request types with the same logic.
Keryx provides automatic CLI flag generation from Zod schemas and background task enqueueing via Redis.
MCP tools are automatically exposed for AI agents without additional configuration.
Comparison table shows Keryx's unique features compared to other frameworks like Hono, Elysia, NestJS, FastAPI, and Django.
Built on Bun with native TypeScript support, including features like bun test with watch mode and native fetch API.
Requires Bun, PostgreSQL, and Redis for setup.
