Install from
The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Clerk has an authorization bypass when combining organization, billing, or reverification checks
Nuxt: Server-Side Remote Code Execution via Runtime Template Injection in Nuxt Server Island Props
Nuxt: Unauthenticated CPU exhaustion parsing and hashing the Nuxt island endpoint body before hash validation
Nuxt: Unauthenticated out-of-memory crash via unbounded v-for expansion in island rendering
Nuxt: Route-rule middleware bypass via case-sensitivity mismatch between vue-router and the routeRules matcher
CLERK_SECRET_KEYThe server owns the Clerk secret key. Set in your .env file and all requests use that single key. No headers needed from clients.Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
14/14 tools missing one or more hints — clerk_create_invitation (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); clerk_create_organization (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); clerk_delete_organization (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tests exist
No test files found
Add tests that exercise each declared tool.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 5 high severity in production deps — @clerk/backend@2.32.0 (high), nuxt@4.3.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
