Introducing Fine-Grained Authorization for Mastra (Mastra)
Mastra adds fine-grained authorization: per-user, per-resource checks gating HTTP routes, agent calls, workflow runs, tool calls, memory reads and writes, and hosted MCP servers. It supplements Mastra's role-based access control and ships in the Enterprise Edition.
In plain words
- Mastra added detailed controls for deciding which users can access specific parts of its Enterprise Edition.
- Each request can be checked against the exact user and the specific item they want to use.
- The checks cover web requests, artificial intelligence actions, automated task runs, tool use, and saved information.
- These checks work alongside broader roles such as ordinary user or administrator.
- Companies gain tighter control over what each person can see or do when broad roles allow too much.

- Malicious skills hijack agents mid-task, and debate training curbs reward hacking
