Hey Product Hunt — Qasim from Nylas here.
We built Nylas CLI because every AI agent demo I saw was hitting a wall the same way: "your agent can read your inbox" turned into 200 lines of OAuth code, a Gmail-only integration, and a token refresh bug three days later.
So we shipped one binary that solves it for 6 providers Gmail, Outlook, Exchange, Yahoo, iCloud, IMAP through a single auth flow. Run `nylas mcp install` and Claude/Cursor/your agent of choice gets 16 tools: send mail, search threads, create events, look up contacts, the lot.
A few things we got obsessed with:
- One auth flow: OAuth for Google/Microsoft, app passwords for Yahoo/iCloud, server config for Exchange all hidden behind `nylas auth`. You never write provider-specific code.
- MCP native: The CLI is the MCP server. No second binary, no daemon. Tools are typed, errors are structured, agents handle them well.
- Open source.: MIT, written in Go, single static binary. No telemetry, no signup wall.
Would love feedback especially from anyone building agents that need email/calendar access. What's the workflow we should optimize for next?
