Cosmos Week 28 Release Notes

MCP

  • New connectors: added out-of-the-box Salesforce and Datadog MCP servers to the catalog.
  • Live attach: add an MCP server to a running session without restarting the VM.
  • Composer @-mentions: attach MCP servers by @-mention directly in the chat composer.
  • Reliability: clearer connection status and friendly names for failed servers, plus fewer spurious OAuth "Reconnect" prompts.

Sessions

  • Tunnels: open a port to a cloud environment to access running services, like your development server, from anywhere.
  • Usage & cost: see per-turn and per-session usage and cost, with accumulated cost badges, in the session details.
  • Session details: session creator, originating webhook, and linked environment now shown.
  • Attachments: upload SVG files as chat attachments.

Admin, Configuration, and Settings

  • Experts: view expert version history and roll back to previous version.
  • Spaces: MCP servers and secrets can be assigned to multiple spaces.
  • Settings: moved all personal and organization settings into a single settings navigation.

Application

  • Sidebar: display settings (filters, sort, density), pinned-folder controls, empty-folder tidy-up, and "Archive all sessions" for folders.
  • Mark unread: mark sessions — including active ones — as unread.
