More resilient chat when optional MCP connectors fail

Chat is more resilient when optional MCP connectors fail: fixes a Codex connector crash, filters out unhealthy connections, and isolates errors.

Highlights

  • Chat sessions are now more resilient when an optional MCP (Model Context Protocol) connector fails or is unavailable.
  • MindMux keeps only healthy MCP connections and isolates connector errors so they can’t interrupt your conversation.

Fixes

  • Fixed a crash when spawning the Codex MCP connector (an EBADF file descriptor error).
  • Unhealthy MCP connections are now filtered out instead of being left in a broken state.
  • Optional MCP connector failures are isolated so they no longer break your chat session.
