Overview
The 1Password MCP Server lets MCP clients such as Codex , Cursor , and Kiro securely manage your 1Password Environments. The server can only see variable and Environment names, and never returns the secrets stored in your Environments, which stay safe in 1Password. Create, list, and rename Environments. List the names of variables stored in an Environment. Add variables to an Environment. Create locally mounted .env files that make your secrets available on demand without writing them to disk. List locally mounted .env files.
