🔒 Security Auditing

This project uses audit-ci for dependency vulnerability scanning in CI/CD. To manage security vulnerabilities:

  • Configuration: Edit audit-ci.jsonc to add vulnerabilities to the allowlist
  • Run audit: pnpm run audit:ci (fails on moderate+ vulnerabilities not in allowlist)
  • CI/CD: Security audit runs automatically on all PRs and pushes to main

To allowlist a vulnerability, add its identifier to audit-ci.jsonc:

{
  "allowlist": [
    "GHSA-xxxx-xxxx-xxxx",  // GitHub Security Advisory
    "CVE-2024-xxxxx",       // CVE identifier
    "1234567"               // NPM advisory ID
  ]
}

📚 Documentation

Full documentation and usage examples are available in the library/ package.

🚨 Legacy OAuth Mode

For backward compatibility, the auth() middleware automatically includes legacy OAuth endpoints that allow MCP servers to act as OAuth servers. This mode is enabled by default but is deprecated.

The following endpoints are automatically exposed:

  • /.well-known/oauth-authorization-server - OAuth server metadata
  • /authorize - Authorization endpoint (proxies to Civic Auth)
  • /token - Token endpoint (proxies to Civic Auth)
  • /register - Registration endpoint (if supported)

To disable legacy mode:

app.use(await auth({
  enableLegacyOAuth: false  // Disable legacy OAuth endpoints
}));
