Your inbox,
now a tool call

Connect once. Use Upstream from any agent.

One MCP
Three ways to use it

Codex

Programmatic. Drop the MCP into a CI step or a cron job. Your inbox triage happens before you're even awake.

Claude

Conversational. Describe the outcome, skip the steps. "Sort my inbox by what blocks the release" and it runs.

Cursor

In-flow. The inbox lives beside your code. Resolve a thread, jump back to the line you were on.
