MCP Auth Workflow

bkend MCP does NOT have dedicated auth tools. Use this workflow:

1. **Search docs**: `search_docs` with query "email signup" or "social login" 2. **Get examples**: `search_docs` with query "auth code examples" 3. **Generate code**: AI generates REST API code based on search results

Searchable Auth Docs

| Doc ID | Content | |--------|---------| | `3_howto_implement_auth` | Signup, login, token management guide | | `6_code_examples_auth` | Email, social, magic link code examples |

Key Pattern

User: "Add social login"
  → search_docs(query: "social login implementation")
  → Returns auth guide with REST API patterns
  → AI generates social login code

REST Auth API (Core Endpoints)

For the complete endpoint list, use `search_docs` or check Live Reference.

| Method | Endpoint | Description | |--------|----------|-------------| | POST | /v1/auth/email/signup | Sign up | | POST | /v1/auth/email/signin | Sign in | | GET | /v1/auth/me | Current user | | POST | /v1/auth/refresh | Refresh token | | POST | /v1/auth/signout | Sign out | | GET/POST | /v1/auth/:provider/callback | Social login callback | | POST | /v1/auth/password/reset/request | Password reset | | POST | /v1/auth/password/reset/confirm | Confirm reset | | POST | /v1/auth/password/change | Change password | | GET | /v1/auth/sessions | List sessions | | DELETE | /v1/auth/sessions/:sessionId | Remove session | | DELETE | /v1/auth/withdraw | Delete account |

**Additional endpoints** (MFA, invitations, user management): use `search_docs` or Live Reference.

RBAC (Role-Based Access Control)

| Group | Description | Scope | |-------|-------------|-------| | admin | Full CRUD | All data | | user | Authenticated user | Full read, own write | | self | Owner only | createdBy-based | | guest | Unauthenticated | Read only (usually) |

RLS (Row Level Security)

• Per-table row-level access control
• 4-level policies: admin/user/self/guest
• Auto-filtering based on createdBy field

Session Management

• Per-device session tracking
• `GET /v1/auth/sessions` - List sessions
• `DELETE /v1/auth/sessions/:sessionId` - Remove session
