Introducing Mastra CLI Actions for Claude Code, Cursor, and Codex

Claude Code, Cursor, and Codex can now test drive your Mastra projects with CLI Actions.

Coding agents have been able to write Mastra code for a while now — through Mastra skills and the MCP docs server. What they couldn’t do was run projects.

CLI Actions expose the same functionality as Studio, but as commands your coding agent can use to run agents and workflows, search memory, investigate failures, and improve agents.

For example, imagine your agent’s response is wrong. You describe what’s happening to your coding agent; it pulls the trace, spots the problem, edits the instructions, then runs an experiment to confirm the fix — all by itself.
