Auth0 MCP Server: Give AI Agents Access to Identity and Auth Data

Why Give AI Access to Auth0?

Auth0 handles authentication and authorization for millions of applications. Tenants, users, roles, connections, rules, and login logs live in the Auth0 dashboard. When you need to check a user's login history, verify role assignments, or debug a connection issue, you navigate the Auth0 management console and filter through multiple sections.

An MCP server for Auth0 lets your AI agent query users, roles, connections, rules, and login events directly from Claude, Cursor, or Windsurf.

What Becomes Possible

Once your AI agent has Auth0 access:

• "How many failed login attempts has user@example.com had today?"
• "Which roles are assigned to the admin group?"
• "Is the Google social connection configured for our production tenant?"
• "Show me users who signed up in the last 24 hours"
• "What rules are active and in what order do they execute?"
• "Which applications use the Username-Password-Authentication connection?"

How It Works

1. Go to DataFaucet and enter your Auth0 dashboard URL (e.g. https://manage.auth0.com)
2. Log into your Auth0 tenant
3. Browse users, applications, connections, and logs as you normally would
4. Each management API call becomes an MCP tool your AI can invoke
5. Deploy and connect to Claude, Cursor, or Windsurf

The AI agent gets whatever access your management API token permits.

Security Best Practices

• Read-only scopes — create a Machine-to-Machine app with read:users, read:roles, read:logs only
• No write scopes — prevent AI from creating users, updating passwords, or modifying rules
• Tenant isolation — scope the token to a single tenant
• Token expiry — use short-lived access tokens with rotation
• Audit logging — Auth0 logs all management API access in the tenant logs

Use Cases by Role

Backend developers: Auth debugging. "Why is this user's login failing? What connection are they using?" without opening the dashboard.

DevOps engineers: Tenant health. "How many active users and which connections are configured?" for environment verification.

Security engineers: Suspicious activity. "Show me all logins from unusual IP ranges in the last hour" for threat monitoring.

Support teams: User lookup. "What's this user's email verification status? When did they last log in?" for ticket resolution.

Auth0 Dashboard vs AI Agent

Getting Started

Set up read-only access for your AI agent:

1. Go to Applications → Machine-to-Machine Applications → Create
2. Authorize it for the Auth0 Management API
3. Grant only read scopes: read:users, read:roles, read:connections, read:logs
4. Copy the client ID and secret

Then point DataFaucet at your Auth0 management dashboard, authenticate with the M2M credentials, and your AI agent can query identity data as MCP tools.
