More Details Connect to Claude

Connect your FusionAuth instance to any AI agent to streamline identity management and authentication workflows through natural conversation.

What you can do

  • User Management — Create, retrieve, update, and delete users. Search by ID, email, or username using the get_user and create_user tools.
  • Application Control — List all applications and drill down into specific configurations using list_applications and get_application.
  • Role Management — Define and retrieve application-specific roles for granular access control with list_application_roles.
  • Authentication Flows — Test login and MFA sequences directly through the API using login and mfa_login.
  • Flexible Updates — Perform full updates with update_user or partial modifications with patch_user to maintain clean user data.

How it works

  1. Subscribe to this server
  2. Enter your FusionAuth URL and API Key
  3. Start managing your identity stack from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • DevOps & SREs — quickly audit user accounts, check application roles, and manage permissions without leaving the terminal or IDE.
  • Backend Developers — test authentication flows and verify user metadata during integration directly from the code editor.
  • Security Teams — inspect user profiles and application access levels to ensure compliance and rapid incident response.

List all our applications in FusionAuth.

I've retrieved your applications. You have 3 active apps: 'Main Web Portal' (ID: 8a7...), 'Mobile API' (ID: 2f1...), and 'Internal Dashboard'. Which one would you like to inspect?

Find the user with email 'admin@company.com'.

I found the user: Admin User (ID: 550e...). Their account is currently 'Active' and they belong to the default tenant. Would you like to see their full profile data?

Create a user with the email 'test@example.com' and username 'test_user'.

User 'test_user' has been created successfully with ID 9b1... and email 'test@example.com'. I can now assign roles to this user if you provide an application ID.

Yes! The `get_user` tool allows you to search by `username`, `email`, or `loginId` in addition to the `userId` UUID.
