A tiny macOS utility for agents

Secrets,
without the terminal.

Fidelius lets an agent open a small native window when it needs credentials. You paste the keys. They go to macOS Keychain. The agent keeps working.

I need these to finish the scrape.

The agent asks. You paste. Fidelius disappears.

01

Agent asks

The agent runs Fidelius with the Keychain service and the secret names it needs.

02

You paste

A normal Mac app window stays available in Cmd-Tab while you provision the keys.

03

Keychain keeps them

Press Enter. Fidelius saves the values, reports only character counts, and closes.

Unix on either side

Fidelius only handles the human part.

It is not a secret manager. Once the keys are saved, agents use Apple’s familiarsecurity CLI to pipe them wherever they need to go.

Ask for keysfidelius -s scraper -m "I need these to finish the scrape." OPENAI_API_KEY STRIPE_SECRET_KEY
Read later with Keychainsecurity find-generic-password -s my-app -a OPENAI_API_KEY -w

Fidelius never prints secret values.

The CLI blocks until you save or cancel, then returns a clean status to the agent.
