## About

# 1Password Kiro Plugin

A Kiro plugin that connects Kiro to the 1Password desktop app's local MCP
server for [1Password Developer Environments](https://www.1password.dev/).

The plugin lets Kiro help with secure project environment setup — listing
Developer Environments, inspecting variable names, adding variables, and
creating local `.env` mounts. Secret values stay controlled by 1Password and
are never shared with Kiro.

> **Platform:** The 1Password Kiro Power is currently macOS only.
