Keryx FAQs

Question 1

What are the benefits of Keryx's input validation and frontend integration?

Accepted Answer

Keryx uses Zod for type-safe input validation, generating automatic error responses and OpenAPI documentation. For the frontend, it provides strongly-typed API responses without manual code generation, ensuring type safety from backend to UI.

Question 2

What is Keryx?

Accepted Answer

Keryx is a fullstack TypeScript framework built on Bun that allows developers to define backend actions once and deploy them across various transports, including HTTP, WebSockets, CLI, background tasks, and AI agent tools (MCP).

Question 3

Is Keryx suitable for AI agent and LLM tool integration?

Accepted Answer

Yes, Keryx is MCP-native, meaning every action is automatically exposed as an MCP tool for AI agents and LLMs. It includes built-in OAuth 2.1 authentication, typed errors, and per-session isolation without needing separate schemas.

Question 4

How does Keryx simplify multi-transport API development?

Accepted Answer

Keryx's core idea is to 'write your controller once, and it works everywhere.' A single action class handles HTTP requests, WebSocket messages, CLI commands, background tasks, and MCP tool calls with the same inputs, validation, and responses, eliminating duplication.

Question 5

How does Keryx handle background tasks and streaming responses?

Accepted Answer

Keryx features built-in background task processing via node-resque, supporting job queuing, scheduled execution, and a fan-out pattern for parallel processing. It also enables actions to return `StreamingResponse` objects for SSE, chunked binary, and cross-transport streaming.
