Mastra Factory is an open-source framework and comprehensive platform for building AI agents and generative workflows in TypeScript. Developed by the Mastra team, it offers an integrated solution combining memory, tool calling, Model Context Protocol (MCP), and observability in a single development environment. Officially launched in October 2025, the platform targets developers and enterprises aiming to move AI agents from prototype to production.
Architecture and Core Components
Mastra employs a layered architecture separating the orchestration layer, model layer, and storage layer. This design enables developers to build complex agents capable of multi-step reasoning while maintaining conversation context across sessions. The framework supports graph-based workflow engines for deterministic task execution, making it suitable for sensitive applications requiring reproducible results.
Agent Engine
Mastra provides a unified API for defining agents with their tools and capabilities. A single agent can call external tools (APIs, databases, web services) and make decisions based on those call results. The framework supports short-term and long-term memory, allowing agents to remember user preferences and historical context.
Built-in RAG Support
Mastra includes native support for Retrieval-Augmented Generation (RAG) with multiple vector stores, chunking mechanisms, and embeddings generation. This enables building applications relying on private knowledge bases without external tools.
Observability and Telemetry
The platform offers an advanced monitoring system tracking observability events, CPU time consumption, and data retention. These features are essential for enterprises needing to monitor agent performance in production and diagnose issues quickly.
Performance and Integration Features
Mastra supports dynamic model routing, allowing switching between OpenAI, Anthropic, Google, and others based on need or cost. It also provides a local development server to accelerate the development cycle, and evaluation tools (Evals) to measure agent output quality. Projects can be deployed directly to Mastra Cloud or self-hosted for full data control.
