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.

Tool calls & MCP

Execute real-world actions

Long-term + working memory

Recall relevant context

Logs, traces, and evals

Trace execution & score output

Orchestrate agent networks

Compose agents with workflows for increased reliability

Agentic workflows

Specify execution paths for increased control

Assemble a team of agents for increased power

context and guardrails

Customize your agents' tools, dynamically inject context, and enforce guardrails.

Human in the loop

Suspend/resume for human review

Runtime context & auth

Configure access from dynamic user context

Security & guardrails

Guard against prompt injection and data leaks
