Question 1

What is Mastra Server?

Accepted Answer

Mastra Server is purpose-built for Mastra. Deploy on infrastructure that understands agents, workflows, memory and telemetry with zero configuration. One command takes your local agent to a live endpoint. Mastra Server exposes your agents and workflows as API endpoints automatically, handles routing and scaling and plugs into React, mobile, Slack or whatever your users already live in. Secure endpoints with JWT, Clerk, Supabase, Firebase, Auth0 or WorkOS. Your agents are part of your infrastructure.

Question 2

How does shipping a Mastra agent in one command work?

Accepted Answer

Mastra Server takes your local agent to a live endpoint with a single CLI command. The server handles request routing, middleware execution, authentication and streaming responses. Extend it with custom API routes, middleware and request context. Secure endpoints with JWT, Clerk, Supabase, Firebase, Auth0 or WorkOS. Mastra Server redacts system prompts, tool definitions and API keys from streaming responses before they reach clients.

Question 3

How does Mastra Server expose agents as API endpoints?

Accepted Answer

Mastra Server automatically exposes all registered agents and workflows as REST API endpoints when you deploy. Explore all available endpoints in the OpenAPI specification at /api/openapi.json or test them interactively in the Swagger UI at /swagger-ui. Call agent and workflow endpoints from any service, at any scale.

Question 4

How do I deploy to Mastra Server?

Accepted Answer

Mastra Server deploys with a single mastra server deploy command that creates a live endpoint with routing, scaling and infrastructure handled for you. The CLI outputs the URL of your deployed Server instance on a successful deploy.

Question 5

What authentication providers does Mastra Server support?

Accepted Answer

Mastra Server supports JWT, Clerk, Supabase, Firebase, Auth0 and WorkOS for securing agent endpoints. Configure authentication by adding an auth provider to your server configuration. Use middleware to intercept requests for authentication, logging, CORS or injecting request-specific context.

Question 6

Can I use Mastra Server with my existing HTTP framework?

Accepted Answer

Mastra Server supports adapters for Express, Hono and other HTTP servers. Custom adapters let you build support for frameworks not officially supported. The Mastra Client SDK provides a type-safe client for calling agents, workflows and tools from browser or server environments.

Question 7

How does Mastra Server handle stream data redaction?

Accepted Answer

Mastra Server redacts system prompts, tool definitions, API keys and similar data from every streaming response before sending it to clients. Stream data redaction is enabled by default for both the generated server and server adapters.
