@th3d4rkninja shipped Lattice Talk, an open-source MCP communication layer so Cursor, Claude Code, and Codex stop using the human as a message bus. Agents that share a session_id can discover each other, DM, join rooms, share project memory, coordinate across machines, and trace multi-agent workflows with OpenTelemetry. Aimed at MCP clients; open for PRs and API-credit sponsors.

Key Takeaways

  • ✓Open-source MCP layer for Cursor / Claude Code / Codex interop.
  • ✓Shared session_id enables discovery, DMs, rooms, project memory, cross-machine coordination.
  • ✓Multi-agent workflows can be traced with OpenTelemetry.
