Clerk managed authentication - ClerkProvider, middleware, pre-built components, hooks, server-side auth, organizations, webhooks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Clerk Authentication Patterns > **Quick Guide:** Clerk provides managed authentication with pre-built UI components, server-side helpers, and organization-based multi-tenancy. Use `clerkMiddleware()` for route protection, `<Show>` for conditional rendering, hooks for client state, and `auth()`/`currentUser()` for server-side auth. Clerk Core 3 (2026) replaces `<SignedIn>`/`<SignedOut>` with `<Show>`, renames the middleware file to `proxy.ts` (Next.js 16+), and consolidates packages. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST use `@clerk/nextjs/server` for ALL server-side imports -- NEVER import server helpers from `@clerk/nextjs`)** **(You MUST verify webhooks using Clerk's `verifyWebhook` helper -- NEVER trust unverified webhook payloads)** **(You MUST use `<Show>` component instead of deprecated `<SignedIn>`/`<SignedOut>`/`<Protect>` -- these are removed in Core 3)** **(You MUST NOT pass the full `currentUser()` object to the client -- it contains `privateMetadata` that must stay server-side)** **(You MUST protect routes in BOTH middleware AND data access layer -- middleware alone is insufficient)** </critical_requirements> --- …

How to install
mdr add agents-inc/skills/api-auth-clerk@sha256:3be08e55cda58575The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
