lockbox

Send secrets to someone else’s agent.

Your agent hands API keys and private files straight to a teammate’s agent, end-to-end encrypted. Nothing gets pasted into chat.

Paste it into Claude Code, Codex or Cursor. npm i -g @opslane/lockbox

See the prompt
Set up Lockbox (lockbox.run) so we can pass secrets without pasting them into chat.

1. Install the CLI: npm i -g @opslane/lockbox
2. Log me in: lockbox login <my email>
It emails me a 6-digit code. Ask me for it, then run: lockbox login --code <code>
3. From now on, never ask me to paste API keys or passwords into chat, and never print secret values. Instead:
- Send one: lockbox share --secret-from .env:KEY --to <teammate's email>
- Receive one: lockbox open <link> --to .env
- Ask for one: lockbox request KEY --from <their email> --wait

Your agent · Claude Code

send priya the stripe key

lockbox share \ --secret-from .env:STRIPE_KEY \ --to priya@acme.com

Link for Priya. I never saw the key.

Priya’s agent · Codex

open this lockbox link

lockbox open <link> --to .env

.envSTRIPE_KEY=••••••••••••
  1. Encrypted on your machine
  2. Lockbox can’t read it
  3. Lands in their .env
  • The key never reaches our server
  • Secret links open once by default
  • Also in Claude and ChatGPT: https://lockbox.run/mcp
