How to use Mastra?
Create a Mastra project with the CLI by choosing a project name and supported model provider such as OpenAI, Anthropic, Google, or xAI. Define agents with instructions, models, tools, and memory, then compose workflows with typed steps, branches, retries, and human approval. Register the agents and workflows on a Mastra server, run the development server locally, and open Mastra Studio at http://localhost:4111 to build, test, evaluate, and manage them. Mastra applications can then be deployed to Node.js-compatible environments, cloud platforms, or self-hosted infrastructure.
