Score Breakdown
⚙ Agent Friendliness
🔒 Security
Admin key = full user DB access — protect critically. User PII. Restrict agent access. Official BetterAuth MCP.
⚡ Reliability
Best When
An agent needs to manage or debug BetterAuth authentication — for admin workflows, user management, or auth troubleshooting in applications built with BetterAuth.
Avoid When
You're using Auth0, Clerk, Supabase Auth, or other authentication providers — use their specific MCPs or management consoles.
Use Cases
- • Managing user accounts and sessions from user management agents
- • Debugging authentication issues from DevOps agents
- • Querying user authentication status from admin agents
- • Automating user provisioning and deprovisioning from HR workflow agents
- • Auditing authentication events from security monitoring agents
- • Testing authentication flows from QA agents
Not For
- • Teams not using BetterAuth for authentication (Auth0, Clerk, Supabase Auth use different MCPs)
- • Public-facing user registration flows (admin/backend operations only)
- • Teams using NextAuth.js or other auth libraries
Interface
Authentication
BetterAuth secret key required for admin API access. Same secret key used to initialize BetterAuth in your application. Provides full admin access — treat as high-privilege.
Pricing
BetterAuth and its MCP server are both free and open source. Official MCP from BetterAuth team.
Agent Metadata
Known Gotchas
- ⚠ Secret key provides full admin access to all users and sessions — extremely high privilege
- ⚠ BetterAuth version compatibility: MCP must match your BetterAuth version
- ⚠ Operations affect real production user accounts — test in development environment first
- ⚠ User data is sensitive PII — handle with appropriate care and access controls
- ⚠ Official BetterAuth MCP — higher quality than community alternatives but newer project
- ⚠ Database access depends on BetterAuth adapter (Prisma, Drizzle, etc.) — adapter must be configured
