Mastra Agents

From memory to MCP, build stateful agents.

Use any LLM to create agents that can reason, decide, and act.

You are an enterprise search agent. You should search across internal wikis, Slack threads, and PDFs. Prioritize context based on the role of the user (such as marketing, sales, etc.)

You are a copywriting agent. Based on the current marketing copy and website, write additional content and generate an image given the product specifications of the user.

built-in agent primitives

Mastra agents come with memory, tool calling, MCP, logging, tracing, and eval primitives. Use them in a local playground or deploy to production.
