Story

@mastra/core 1.68.0 ships @mastra/mcp 2.0.0 supporting only the 2026-07-28 MCP revision, dropping the initialize handshake and session headers. Tools needing input now suspend and resume via context.suspend() with signed self-contained state. It also stops durable agents persisting "running" checkpoints by default. Older MCP clients break against Mastra servers after this.
