Overview
Atmosphere is a real-time AI agent runtime for the JVM. A single @Agent class runs on Spring AI, LangChain4j, Anthropic, or other runtimes behind one SPI, with token streaming, tool calls, human approvals, and governance. It streams over WebSocket, SSE, gRPC, and more, and exposes MCP, A2A, and AG-UI endpoints, with built-in memory, planning, a virtual filesystem, and sub-agent delegation.
