Grok Build shipped v1.0.33 with stronger MCP, memory, and long-session reliability: MCP tool results can include structured JSON, cancel/timeout notifies the server to stop work, /memory supports two-press delete for real notes, and compaction checkpoints survive the 30-day cleanup so long agent workflows keep context. Elon Musk amplified the update.
