Mastra 1.60.0 adds opt-in support for the stateless MCP 2026-07-28 revision and multi-round elicitation
GitHub (mastra-ai/mastra)·high signal
Released 19 Aug 2026, @mastra/core 1.60.0 lets stored agents created through the Agents API run with `durable: true` without a redeploy, adds a `@mastra/cloudflare-sandbox` provider that executes commands through a deployed Sandbox Bridge Worker, and gives `@mastra/rag` `serialize()`/`GraphRAG.deserialize()` so knowledge graphs survive restarts. `@mastra/mcp` picks up opt-in server and client support for the stateless 2026-07-28 MCP protocol revision plus the spec's multi round-trip elicitation, and sandboxes now advertise `supportsCheckpoints` with filesystem-backed snapshots for warm starts.
