Mastra: the factory infographic
A leading open-source TypeScript framework for building production AI agents.
What the company does
In normal terms
Open-source TypeScript framework and enterprise platform for building, iterating and managing production-grade agents.
Mastra gives developers the parts to build agents, workflows and tool integrations, and a platform to run and manage them in production.
In lay terms
Mastra is a Lego kit for building AI assistants, plus a garage for keeping them running.
The risks it faces, especially from AI agents
In normal terms
- Easy to add tools. Frameworks make adding tools and integrations easy; each one widens what the agent can reach.
- Many agents, little record. Teams ship many agents quickly; few write down what each is for or who owns it.
- Shared state and secrets. Agents share memory, keys and state; a leak in one reaches the others.
In lay terms
- Easy to add tools. With Lego it is easy to add one more arm, and every arm can grab something.
- Many agents, little record. Lots of robots in the garage, no labels on any of them.
- Shared state and secrets. All the robots share one toolbox and one set of keys.
How RiskMandate helps
- Reachwhat it can actually access or affectThe tools and integrations each Mastra agent is wired to.
- Mandatewhat the business authorisedThe workflow it was built for.
- Gapthe difference: the riskTools registered but not needed for that workflow.
- Barrierswhat really stands in the wayFramework guards, approvals and tests, named with evidence.
- Provenancewho owns it, who reviewed it, which versionThe owner and version of each agent in the platform.
In normal terms
A behaviour policy could be generated from a Mastra agent's own definition (its tools and workflows) and kept beside the code, so every agent ships with a record of its reach and mandate. Encrypted shared state (sgit vaults) answers the shared-secrets risk.
In lay terms
Mastra builds the robots; RiskMandate puts a label on each one: what it is for and what it must not touch.
A first line for the conversation: Every Mastra agent already declares its tools. We could turn that into a behaviour policy automatically. Worth a try?
