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.

為 AI Agent 打造的版本化檔案系統
100% 相容 POSIX 的掛載方式,讓 Agent 與沙箱使用熟悉的 Unix 工具,持久化、同步與版本歷史在底層透明處理。
毫秒級分叉工作區,在隔離分支上執行數十個 Agent,最後選出最佳結果,無需檔案鎖。
在每一步為整個檔案系統打快照,Agent 出錯時可透過一次 API 呼叫恢復任意歷史狀態。
隨時暫停 Agent 等待審核,建立審批佇列與策略閘門,然後從完全相同的工作區狀態繼續。
