Mastra is an open-source TypeScript framework for building, deploying, and observing AI agents and workflows. It gives JavaScript developers typed agents, durable workflows, memory, MCP tool support, and built-in observability so prototypes can scale into production.
Mastra is an open-source TypeScript framework for building, deploying, and observing AI agents and workflows. It gives JavaScript developers typed agents, durable workflows, memory, MCP tool support, and built-in observability so prototypes can scale into production.
Define agents with instructions, models, tools, and runtime behavior, then compose typed workflow steps with retries and branching in TypeScript.
Give agents long-lived context with observational memory, semantic recall, and thread-aware storage.
Traces, metrics, logs, and datasets show every model call, tool call, and handoff in a searchable timeline.
Score agent runs against repeatable checks and experiments before changes reach production.
可在終端自由重塑的極簡編程代理
用 TypeScript 擴充建構命令、工具、快捷鍵、浮層、子代理或權限攔截，也可從 npm 與 git 以套件形式安裝。
AGENTS.md 指令、專案層級 SYSTEM.md、按需技能、提示範本與可自訂壓縮，讓上下文視窗完全可控。
