Use when customizing, branding, or replacing the built-in FrontMCP OAuth pages (the login, consent, federated-select, incremental-authorization, and error pages) with your own React components.

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
# FrontMCP Custom Authorization UI (`auth.ui`) Entry point for replacing FrontMCP's built-in OAuth pages (login, consent, federated, incremental, error) with your own React components. Custom UI is a simple **slot→file map** (`auth.ui`) plus an extras **name→handler map** (`auth.extras`) on the auth config — there is no decorator and no class. The `references/custom-auth-ui.md` reference has the full API; the `examples/` show a single login slot and a multi-step extras form. ## When to Use This Skill ### Must Use - Branding or fully replacing the `local`/`remote` mode **login** page with a custom React component - Building a custom **consent** screen, **federated** provider picker, **incremental** authorization, or **error** page - Adding a server-validated multi-step field to an authorization page (e.g. "add another item") via `auth.extras` ### Recommended - Understanding which half is the server (`auth.ui` / `auth.extras` in `@frontmcp/sdk`) and which is the client (`@frontmcp/ui/auth`) - Looking up the `AuthFlowState` fields a slot component receives, or the `/oauth/ui/extra` route - Confirming that the framework (not your component) owns CSRF + CSP ### Skip When …

mdr add agentfront/frontmcp/frontmcp-auth-ui@sha256:e6f5a3c3d1a9c398The line at the top of this page pins the label git:20261011.3484b44, 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.
