Backend SDK for validating MonoCloud-issued access tokens in Fastify APIs. Same engine as the Express adapter — handles JWT signature verification (via JWKS) and opaque-token introspection automatically based on token format.
Monocloud Auth Fastify is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/monocloud-auth-fastify/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when integrating MonoCloud access-token validation into a Fastify API — installing or configuring `@monocloud/backend-node/fastify`, wiring the `protectApi()` `onRequest` hook factory, validating JWT or opaque (introspection) bearer tokens, enforcing scopes/groups, attaching `claims` to `request` via `AuthenticatedFastifyRequest`, or troubleshooting `MONOCLOUD_BACKEND_*` env vars / audience / JWKS / mTLS certificate binding.
The Monocloud Auth Fastify Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
