Users who run several AI coding agent sessions at once (for example multiple Claude Code processes, or a laptop plus a cloud workstation) share one Harness MCP sign-in. When one session signs in again, the other sessions can lose their access and have to re-authenticate, often well before they would expect, which interrupts long-running work. Please support multiple concurrent Hosted MCP sessions per user, so signing in from one process or machine does not end the others.

This matters for teams that work on several tasks in parallel with AI agents: today they either serialize their sessions or re-authenticate repeatedly.
