## What it does

This skill separates three unrelated cases: app-user login through Netlify Identity, blocking access to the site itself, and SAML SSO for the Netlify dashboard. It helps select a private project, shared password, team login protection, or strict SSO access. It also covers inviting Reviewers and reading `context.user` in functions and edge functions.

Protection settings are changed in the Netlify dashboard. They have no public API, CLI command, or MCP tool, so the skill provides the UI route and a checklist instead of changing settings directly. It also explains SSO expiry: protected-site tokens last 1 hour, and `Netlify-Site-Protection-Expires-In` reports the remaining time before a request can return `401`.

This skill does not wire authentication into application code. App-login setup belongs to `netlify-identity`. On Free and Personal plans, shared password protection is unavailable, so viewers must be restricted through project visibility.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-access-control -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/netlify-access-control/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/netlify-access-control/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-access-control -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/netlify-access-control/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-access-control -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/netlify-access-control/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install netlify/context-and-tools netlify-access-control
```

2. **Manually: put the files in place**
- File: `.github/skills/netlify-access-control/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-access-control -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/netlify/context-and-tools --path skills/netlify-access-control
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/netlify-access-control/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-access-control -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/netlify/context-and-tools/tree/HEAD/skills/netlify-access-control/SKILL.md

## When to use it
- choose the correct Netlify protection layer
- keep production public while securing previews
- distinguish a private project from shared password access
- route team access through SAML SSO
- diagnose 401 responses after SSO token expiry

## Example prompts
- Tell me whether this site needs a private project, password protection, or team login protection.
- Explain the difference between Netlify Identity and SAML SSO for this internal app.
- Why does the SSO-protected site return `401` after about an hour, and how should the session refresh?

description: 'Picks the right Netlify site-protection layer and disambiguates the three unrelated "auth" concepts users conflate — app-user login (Netlify Identity), site-load gating (Password Protection / project visibility), and dashboard SAML SSO. Use it when asked to password-protect a site or Deploy Preview, make a project private/public, restrict a site to your team, require SSO to view a site, set up company-wide or internal-app SSO, invite users to a private project, or know which team member made a request to a private site. Also use it for SSO-session symptoms on protected sites: "logged out mid-session", 401s after about an hour, or token expiry/refresh questions. Not for wiring auth code — route app-login setup to netlify-identity.'

# Netlify access control — pick the protection layer

This skill routes you to the correct protection layer. It does not teach each one. **These settings have no public API, CLI command, or MCP tool.** Never curl `api.netlify.com` or read local auth tokens to inspect or change them — give the user the dashboard path and checklist. On failure, report what you tried and stop.

## First: disambiguate "auth" — three unrelated layers

Users constantly conflate these. Identify which one is meant before recommending anything.

1. **Netlify Identity** — "who is this user *inside my app*." Issues `nf_jwt`. → route to the **netlify-identity** skill; not covered here.
2. **Password Protection / project visibility** — "can this request load the site at all." Covered here.
3. **Team/Org SAML SSO** — "can you log in to the Netlify *dashboard*." Gates dashboard access; also underlies team-login site protection.

Sessions are separate. The same provider (e.g. Google) can appear twice unrelated — Identity OAuth for app users vs. SAML IdP for team members.

**Double-login footgun:** a Password-Protection/team-login perimeter session and an Identity app session have **no bridge** — no shared cookie, no header forwarding, no JWT exchange. Don't try to wire them together. For the combined layered pattern and its tradeoffs, see `references/two-layer-pattern.md`. The Netlify login itself *does* reach app code: on a private project or with team login protection, functions and edge functions receive the signed-in Netlify user as **`context.user`** — if every app user can pass that login, it is the app's identity and no second login is needed.

**Want an internal app with a single sign-in (no double login)?** First ask who uses it:
```
