Cross-Claude MCP – Let multiple Claude instances talk to each other
Multi-Claude coordination via message bus—fills real isolation gap across Claude Code/Desktop/ai.

MCP handoff between Claude and Codex sessions, but orchestration tools already exist.

Every AI session starts with a blank slate. Whatever you built up in the last session, like architecture decisions, debugging history, the reasoning behind every choice, is all gone. So youu re-explain from scratch.
Khala fixes the handoff at the source. Instead of writing a summary file, the sending session packages its full context and delivers it directly to a named inbox. The receiving session picks up exactly where the sender left off. Works across any MCP-compatible tool (Claude, Cursor, Codex, ChatGPT, etc.).
