Mastra rebuilds @mastra/mcp 2.0 on the MCP 2026-07-28 revision: no handshake, signed suspend/resume state
Released 23 September, @mastra/core 1.68.0 ships @mastra/mcp 2.0.0. It supports only the 2026-07-28 MCP revision and drops the initialize handshake and session headers. Tools that need input now suspend and resume through context.suspend() with signed, self-contained continuation state in place of elicitation. The release also stops durable agents persisting 'running' checkpoints by default and adds token-budgeted messageHistory trimming. It is one of the first major TypeScript frameworks to go MCP-v2-only, so older MCP clients will break against Mastra servers.
