Mastra ships v1 ToolProvider runtime plus MicroVM and MySQL backends

Mastra (GitHub Releases)·low signal

The TypeScript agent framework Mastra (June 2, 2026 release) added a v1 ToolProvider runtime with server routes, editor wiring, and client SDK methods for managing OAuth-backed connections, letting stored agents pin specific connections per toolkit at execution time. It also shipped @mastra/mysql as a first-class storage backend (memory, threads, workflows, observability) and @mastra/vercel's VercelMicroVMSandbox — ephemeral Firecracker microVMs with persistent in-session filesystem, ports, and background processes. The MicroVM sandbox is the standout: per-session isolated execution is increasingly table-stakes for safely running tool/code-executing agents.
