feat(cli-auth): add @clerk/cli-auth package

[nicolas-angelo]

Summary

Adds @clerk/cli-auth to the monorepo — an SDK for adding OAuth 2.0 + PKCE localhost-callback authentication to Node.js CLIs that use Clerk.

This builds on clerk/cli-auth-example, a reference implementation for the pattern, and promotes it into an official @clerk/cli-auth package.

From the reference repo (clerk/cli-auth-example)

• ClerkCliAuth class with login(), getAccessToken(), whoami(), logout()
• PKCE + localhost callback HTTP server (S256, random port, state check, timeout)
• Three credential store backends: OS keychain (with file fallback), chmod 0600 JSON file, in-memory
• Token endpoint helpers: exchangeCodeForTokens, refreshAccessToken, fetchUserInfo

import { ClerkCliAuth } from '@clerk/cli-auth';

const auth = new ClerkCliAuth({
  clientId: process.env.CLERK_OAUTH_CLIENT_ID!,
  issuer: process.env.CLERK_ISSUER!,
  scopes: ['profile', 'email', 'openid', 'offline_access'],
  storage: 'keychain',
  keychainService: 'my-app-cli',
});

// Opens a browser, runs the localhost callback, exchanges the code, stores tokens
const { tokens, user } = await auth.login();

// Returns the cached access token; auto-refreshes when within 30s of expiry
const token = await auth.getAccessToken();

// Returns cached user info, or fetches /oauth/userinfo if not cached
const me = await auth.whoami();

// Clears stored tokens (see Token revocation below)
await auth.logout();

Additional changes

API key auth

Added support for Clerk API Key auth alongside OAuth. Verification routes through a consumer-provided backend endpoint where server-side verification (e.g. clerk.apiKeys.verify(token)) can be used.

const auth = new ClerkCliAuth({
  // ...
  apiKeys: {
    verifyEndpoint: 'https://myapp.com/api/verify-key',
    envVar: 'MYAPP_API_KEY',
  },
});

const user = await auth.verifyApiKey('ak_...');

Token resolution

resolveToken() returns { token, kind }, giving CLIs the available credential along with its type (oauth or api_key) so they can route to the right verification path. Checks, in order: (1) a token passed via CLI args, (2) the API key env var named by apiKeys.envVar in the config, (3) the cached OAuth access token. Throws if none are available.

const { token, kind } = await auth.resolveToken({ tokenFromArg: argv.token });
if (kind === 'api_key') {
  // verify via backend endpoint
} else {
  // use as OAuth bearer
}

Token revocation

logout() now hits /oauth/token/revoke at the issuer by default, so the refresh token is invalidated remotely instead of just being dropped locally. Opt out with logout({ revoke: false }).

await auth.logout(); // revokes token first, then clears local store
await auth.logout({ revoke: false }); // local cleanup only

Other

• Richer UserInfo interface
• Extended OAuthScope type literal union (user:org:read, public_metadata)
• Tests for the new revoke pathway (cascade from refresh to access token, opt-out, graceful failure when the issuer endpoint errors)

📝 Walkthrough

Walkthrough

This pull request introduces @clerk/cli-auth, a new reusable package for adding OAuth 2.0 + PKCE authentication to Node.js CLI applications. The package includes a localhost callback server for browser-based sign-in, configurable credential storage backends (OS keychain with file fallback, file, or in-memory), automatic token refresh and revocation, userinfo lookup, and optional API key verification. All public types, error codes, and helper functions are properly exported, and the implementation is comprehensively tested with Vitest.
