About atmosphere

Atmosphere The real-time engine for AI agents on the JVM. Tokens flow from the LLM runtime to the client through a broadcaster you can filter, gate, and observe — over WebSocket, SSE, long-polling, or gRPC, and out through MCP, A2A, and AG-UI. A plain @Agent is a full deep agent, batteries-included, and Atmosphere handles reconnect, authorization, and governance. <img src="https://github.com/Atmosphere/atmosphere/actions/workflows/ci-js.yml/badge.svg?branch=main" alt="CI:
