Mastra
TypeScript framework for production AI agents, workflows, and MCP servers
About
Mastra is a TypeScript-first open-source framework for building production AI agents and applications. It provides agents with memory and tool use, graph-based workflows with human-in-the-loop steps, RAG, MCP server support, and built-in evals and observability, with model routing across 40+ providers. It is best for TypeScript/Node teams who want one framework from prototype to a deployed, monitored agent service.

Mastra Studio, the local development UI, then runs at http://localhost:4111. You will need Node.js and an API key for the model provider you configure.
