UpstreamUpstream MCP

Workflows

The Upstream MCP server includes prompt workflows – pre-built multi-step instructions that guide your AI assistant through common email tasks. These are registered as MCP prompts and can be triggered as slash commands in clients that support them (e.g., /inbox-zero in Cursor).

You can also trigger them by asking your AI assistant directly, e.g., “Help me reach inbox zero.”

Inbox Zero

Section titled “Inbox Zero”

Prompt name: inbox-zero

Processes your inbox towards zero unread. The assistant will:

  1. Find your Primary inbox tab
  2. Get unread threads
  3. Summarize each thread
  4. Present a triage table with suggested actions (done, snooze, reply, star)
  5. Group threads by urgency: needs-reply, FYI-only, can-archive
  6. Wait for your confirmation before executing any actions

Example: “Help me reach inbox zero” or use /inbox-zero
