Mastra AI — The Modern Framework for Building Production-Ready AI Agents

Mastra is a TypeScript framework designed to simplify building production-ready AI agents and workflows. It provides autonomous agents with LLM reasoning, graph-based workflow execution (with branching and parallel steps), human-in-the-loop support, built-in memory management, MCP server support, and observability tools. The guide walks through installation via CLI, setting up a project, and building a custom Data Engineer Agent that generates SQL queries and debugs pipelines — demonstrating how Mastra bridges the gap between prototype demos and real production AI systems.
