keryx vs Microsoft AutoGen

keryx: Keryx is a fullstack TypeScript framework built on Bun, designed to write application logic once and deploy it across various transports, including HTTP, WebSocket, CLI, background tasks, and MCP (Model Context Protocol) for AI agents. It automatically exposes all actions as MCP tools, allowing AI agents to authenticate and interact with your application's validated endpoints with type safety.; Microsoft AutoGen: AutoGen is a versatile framework for developing multi-agent AI applications that can operate autonomously or in collaboration with humans. It offers a layered, extensible design, including Core and AgentChat APIs, along with developer tools like AutoGen Studio for no-code GUI development and AutoGen Bench for performance evaluation.

When to choose:
  • You maintain an existing AutoGen v0.2 or v0.4 system, or want to run research artefacts built on it such as Magentic-One and AutoGen Bench.
  • You want to reference its layered event-driven architecture while planning a migration to Microsoft Agent Framework.
When to skip:
  • You are starting a brand-new project; Microsoft states AutoGen is in maintenance mode with no new features and recommends Microsoft Agent Framework.
  • You expect AutoGen Studio to be a turnkey production web app (the README notes Studio is for prototyping only).

Features

keryx logokeryx
01MCP-native actions: Every action is automatically an MCP tool with OAuth 2.1 authentication, typed errors, and per-session isolation for AI agents.
02Transport-agnostic Actions: A single action class handles HTTP, WebSocket, CLI, background tasks, and MCP tool calls with unified validation and middleware.
03Zod input validation: Provides type-safe parameter validation with automatic error responses and OpenAPI generation.
04Built-in background tasks: Utilizes node-resque for background job processing with fan-out patterns for parallel execution.
05Strongly-typed frontend integration: Offers end-to-end type safety for API responses with a companion Vite + React frontend, no code generation needed.
06Streaming responses: Supports SSE, chunked binary, and cross-transport streaming behavior for real-time data flow.
