Gateway Environment Injector

Bake secrets from 1Password into macOS LaunchAgent plists without leaving plaintext keys on disk. Uses op read to fetch secrets and /usr/libexec/PlistBuddy to inject them directly into the plist's EnvironmentVariables block.

Why This Exists

• - launchctl setenv doesn't inject into a plist's own EnvironmentVariables block
• Environment variables in .zshrc aren't available to LaunchAgents
• Plaintext key files are a security risk
• 1Password service accounts provide read-only, rotatable access

Usage

CODEBLOCK0

Reads each key from 1Password, injects into the gateway plist, then restarts the service.

What It Injects

Configurable list of op://Vault/Item/field references mapped to environment variable names. Modify the script's KEYS array for your setup.

Key Lesson

Changing the Node binary path (even to a symlink) can silently revoke macOS TCC permissions. Always keep the gateway plist locked to the Homebrew Cellar path, not an NVM symlink.
