Builds are back up. Our recommendation now: revoke and rotate keys for any env variables stored on Mastra platform.
To reiterate: we have no evidence of impact.

Mastra's platform is hosted on Railway and thus Mastra platform users are affected by the ongoing Railway security incident.
Comms here as things evolve.
We redesigned the Mastra trace viewer so you can follow an agent run as a conversation instead of digging through a tree of spans
Quick demo with real runs from our docs agent
My ambition is for everyone building with Mastra to use Mastra Observability for their traces
This week we shipped
- Thread View
- Metrics API
- Trace imports
- And now trace queries
Live Workshop: Build a Company Brain with Mastra Connect xitter.cf/i/broadcasts/1RJjpbZyd…
Join Charlie and I tomorrow for a workshop on how to build a company brain with Mastra Connect!
You'll learn to:
- Connect an agent to your knowledge bases
- Give it tools to look things up and take action
- Put it in your team's Slack 🚀

Stitching together traces turn by turn and reading span trees is not it 😮💨
Thread View shows you the conversation the way your user experienced it. Add feedback, or dig into the trace behind any turn
Live workshop: Build a ChatGPT Plugin with Mastra xitter.cf/i/broadcasts/1OGwbnkOL…
Before Mastra Connect, giving an agent access to company tools like Notion, Linear, or Slack meant handling OAuth and writing tools yourself, or using a third-party platform.
Now you can connect those accounts with 𝚖𝚊𝚜𝚝𝚛𝚊 𝚌𝚘𝚗𝚗𝚎𝚌𝚝 𝚊𝚍𝚍 and give your agents hundreds of ready-made tools, all within Mastra!
We shipped a new template for monitoring competitor pages.
A page edit doesn't always mean an important update. Use Jev to evaluate each change, and decide if it matters to you.

Wrote the complete guide to running an eval loop with Mastra

If you've got Mastra tools, you're most of the way to a ChatGPT plugin extension.
Thursday, we're wiring one up live, from MCP server to sidebar panel.
Come join us!

Live workshop: Build Secure Agents with Auth and FGA xitter.cf/i/broadcasts/1jGXgBpAw…
Authentication tells you who's signed in. It doesn't tell you whether they're allowed to read a thread, run an agent, or call a tool.
Tomorrow I'm building that layer live with Mastra's fine-grained authorization.
Come join me!

Do not miss!
Jev was announced last week. This week, to help devs dive in, @mastra shipped: workflows classifier, tool approval classifier checks, classifier as judge scorers, classifier as a processor.
@abhiaiyer and I are diving into it all tomorrow. Come thru!
