Cross-session real-time chat MCP server for Claude Code — channels-based daemon push, sub-2s latency, group + handshake. Part of the khimaira workspace.
Project description
khimaira-chat
Cross-session real-time chat MCP server for Claude Code. Daemon-push via claude/channel capability; sub-2s end-to-end latency.
Part of the khimaira workspace.
What it does
- Lets two or more Claude Code sessions hold a real-time chat conversation.
- Messages land in the recipient's context as
<channel source="khimaira-chat" ...>blocks via Claude Code's channels feature. - Groups + handshake — N-session rooms, all members must accept the invite before they receive messages.
- State (rooms, members, transcripts) lives in the
khimaira-monitordaemon; this MCP server is a per-session stdio subprocess that subscribes to its session's events and forwards them to the agent.
Architecture
See tasks/khimaira-chat/IMPLEMENTATION.md in the workspace root for the full design.
Claude Code session ◄── stdio ──► khimaira-chat MCP subprocess ◄── HTTP/SSE ──► khimaira-monitor daemon
Install (per Claude Code peer)
khimaira sync registers this MCP server in your Claude Code config. To launch with channels enabled (research preview):
claude --dangerously-load-development-channels server:khimaira-chat
