About

Strands Agents runs the agent loop inside your own process and has no hosted control plane. The README lists turn limits, token budgets and cancellation, plus tools, structured output, MCP connections and multi-agent patterns. It also lists memory, sessions, streaming, guardrails, tracing and evals among its areas. A harness package assembles a complete agent, and a CLI can chat with it from a terminal.

Use cases: agent-orchestration
