MostlyID

One sign-in for every Mostly Tiny product. Authorize once; your CLI, MCP, and agents are authenticated across the whole portfolio — no per-product API keys.

From an agent or terminal:

npx mostlytiny login

That opens a browser to approve the device, then stores a token your MCP and the Claude/Codex plugins read automatically.

Authorizing a device? You'll land on /device from the link in your terminal.
