Connects Claude to your FusionAuth instance via API, exposing 300+ endpoints for managing users, applications, tenants, and auth configuration. You can restrict operations by prefix (create, delete, update, retrieve, search) to stay read-only or fit within context windows. Built from OpenAPI specs, so you get the full FusionAuth API surface. The team emphasizes this is preview software and recommends pointing it only at dev instances since you're handing your API key to the LLM. Lock down permissions on that key, limit tool prefixes to what you need, and you've got an assistant that can query user counts or provision new applications without leaving your chat.
