Common questions

Is API Locker safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.3) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

API Locker

One vault, three types of credentials. LLM API keys, service API keys, and OAuth credentials — all encrypted, all injectable into your code with a single command.

API Locker replaces the .env file with one encrypted vault. Store your OpenAI key, your Stripe secret, your Google OAuth client — all in one place — and inject them into any command with apilocker run -- npm start. Your raw credentials never touch disk, never live in shell history, never get committed to git.

This is the command-line interface. Website · Dashboard

Install

npm install -g apilocker

Requires Node.js 18 or newer.

Get started in three commands

# 1. Install the CLI (above)

2. Register this device — opens your browser for a one-click confirmation

apilocker register

3. Run any command with your vault secrets injected as env vars

apilocker run -- npm start

That's it. Your process.env.OPENAI_API_KEY, process.env.STRIPE_SECRET_KEY, process.env.GOOGLE_OAUTH_CLIENT_SECRET — everything you'd normally drop in a .env file — is now injected into the subprocess for exactly the duration of that command. When the command exits, the secrets are gone.

One vault, three types of credentials

🧠 LLM API Keys

OpenAI, Anthropic, Gemini, Groq, Mistral.

apilocker store --name OPENAI_API_KEY --provider openai --key sk-proj-xxxxx

apilocker run -- node my-ai-app.js

⚡ Service API Keys

Stripe, Twilio, Resend, ElevenLabs, Cloudflare, GitHub, Clerk, Sentry, PostHog, Cloudinary, Mux, SendGrid, Vercel, Upstash, LemonSqueezy — plus custom for anything else.

apilocker store --name STRIPE_SECRET_KEY --provider stripe --key sk_live_xxxxx

apilocker run -- npm start

🔗 OAuth Credentials

Google, GitHub, Slack, Microsoft, Notion, Spotify, Twitter/X, LinkedIn, Discord, Zoom, Dropbox, Salesforce, HubSpot — plus custom OAuth for anything else.

apilocker store --oauth \

--name google-oauth \ --provider google-oauth \ --client-id 856449...apps.googleusercontent.com \ --client-secret GOCSPX-xxxxx \ --scopes "openid email profile"

Injects GOOGLE_OAUTH_CLIENT_ID, GOOGLE_OAUTH_CLIENT_SECRET, etc.

apilocker run -- node oauth-app.js

The full command set

Command	What it does
`apilocker register`	Register this device via browser confirmation. No pasted tokens.
`apilocker store`	Store a credential. `--oauth` for multi-field OAuth, otherwise `--key`.
`apilocker list`	List credentials grouped into LLM / Service / OAuth buckets. Filter with `--tag`, `--provider`, `--category`, `--search`.
`apilocker run --`	Run any command with vault secrets injected as environment variables.
`apilocker get`	Print a single secret value to stdout (for scripting). `--field` for OAuth fields.
`apilocker env`	Emit shell-eval-able `export` statements. `eval "$(apilocker env)"` to load into current shell.
`apilocker init`	Pin specific keys to a project directory via a committable `.apilockerrc` file.
`apilocker import .env`	Migrate an existing `.env` file into the vault. Pattern-matches provider prefixes and offers to replace the `.env` with an `.apilockerrc`.
`apilocker rotate`	Replace a credential's value. Scoped tokens keep working; rotation is transparent to consumers.
`apilocker rename`	Rename a credential alias. Lossless — existing `.apilockerrc` files that reference the old name keep working via transparent fallback.
`apilocker pause` / `resume`	Freeze proxy access without deleting. Reveal / run / get / env still work on paused credentials.
`apilocker delete`	Permanently delete a credential.
`apilocker devices list` / `revoke`	Manage devices registered to your account.
`apilocker token create/list/pause/resume/delete`	Manage scoped access tokens for app/proxy use.
`apilocker activity`	View the audit log. Add `--follow` / `-f` to stream new events live.
`apilocker doctor`	Security health check: stale rotations, unused keys, expiring tokens, local config permissions.
`apilocker update`	Check npm for a newer version.

The `.apilockerrc` file

Pin a project to a specific set of credentials with a committable config file. apilocker init walks you through creating one:

# .apilockerrc — safe to commit to git, contains only pointers

keys:

OPENAI_API_KEY
STRIPE_SECRET_KEY
google-oauth

After apilocker init, anyone cloning your repo who runs apilocker run -- npm start gets the same env vars — assuming they have access to those aliases in their own vault. It's like a package.json for credentials: the file declares what the project needs, each developer has their own vault.

Why the CLI doesn't ask for a pasted master token

Unlike most developer tools, apilocker register doesn't want you to paste a secret from the dashboard. Instead:

You run apilocker register
Your browser opens to a single-card confirmation page
You click "Authorize"
The CLI receives a per-device master token over an authenticated polling channel — it never touches your clipboard, shell history, or screen

This is the RFC 8628 device authorization flow (the same pattern gh, vercel, wrangler, flyctl, and gcloud use). It's strictly safer than pasted tokens because the secret never appears anywhere a human can accidentally leak it.

New users? The same flow handles signup — your first OAuth click with GitHub/Google creates the account automatically. No separate visit to the web portal required.

MCP integration — connect your AI assistant

API Locker exposes a full Model Context Protocol server with 25 tools so Claude Code, Claude Desktop, Cursor, Zed, Continue, and any other MCP-compatible client can read and manage your vault directly.

Claude Code — one command

claude mcp add apilocker -- apilocker mcp

Verify with claude mcp list. You should see apilocker: apilocker mcp - ✓ Connected. The server is available in your next Claude Code session automatically.

Claude Desktop, Cursor, Zed, Continue

The CLI ships with apilocker mcp — a stdio bridge that handles the connection automatically. Configure any MCP client with:

"mcpServers": { "apilocker": { "command": "apilocker", "args": ["mcp"] } } }

The bridge reads your master token from ~/.apilocker/config.json automatically. No credentials go in the client config itself.

Print client-specific config with the built-in helper:

apilocker mcp config --client claude-desktop   # or claude-code, cursor, continue, zed, generic

Full docs: https://www.apilocker.app/docs/mcp — includes config file locations for each client, troubleshooting, and the full 25-tool catalog.

Visual status: the dashboard has a dedicated MCP panel at https://www.apilocker.app/dashboard#mcp showing server status, a test-connection button, copy-pasteable config for every major client, and a live feed of recent MCP activity.

Security posture

AES-256-GCM encryption on every stored credential. Keys never leave the vault in plaintext except when revealed to an authenticated master-token holder (you).
Per-device tokens with independent revocation. Stolen a laptop? Revoke that one device; every other device keeps working.
OAuth CSRF protection with state tokens bound to a 10-minute KV window.
Strict file permissions (0600) on ~/.apilocker/config.json.
Audit-logged everywhere: every reveal, every proxy call, every rename, every rotation. Watch them live with apilocker activity --follow.
Lossless rename with previous_names fallback: renaming a credential never breaks existing code. Old aliases transparently resolve to the current credential with a gentle nudge to update configs.
Pause/resume to freeze proxy access during incident response without losing the credential itself.

Configuration

Config lives at ~/.apilocker/config.json (mode 0600). Don't check it in.

Override the API endpoint for self-hosted deployments:

apilocker register --url https://api.your-locker.example.com

Status

API Locker is free to use with unlimited keys, unlimited tokens, and unlimited proxy calls. Early adopters get grandfathered into free Pro permanently when paid plans launch.
