OpenFGA (Fine-Grained Auth) MCP Connector for Claude

Connect your OpenFGA instance to any AI agent to manage Relationship-Based Access Control (ReBAC) through natural conversation. OpenFGA is an open-source fine-grained authorization solution inspired by Google's Zanzibar.

What you can do

• Store Management — Create, list, and delete isolated stores to manage authorization data for different environments or applications.
• Authorization Modeling — Define and retrieve complex authorization models using types and relations to represent your system's permissions.
• Tuple Management — Write, read, and track changes to relationship tuples that define which users have which relations to specific objects.
• Relationship Checks — Instantly evaluate whether a user has a specific relation to an object (e.g., 'can user:anne view document:1?').
• Health Monitoring — Quickly check the status of your OpenFGA instance to ensure high availability.

How it works

1. Subscribe to this server
2. Enter your OpenFGA API URL and API Token (if applicable)
3. Start managing your authorization logic from Claude, Cursor, or any MCP-compatible client

Who is this for?

• Security Engineers — Audit relationship tuples and verify authorization models without manual API calls.
• Backend Developers — Quickly test and iterate on authorization models during development directly from the IDE.
• DevOps & SREs — Monitor store health and manage authorization environments across different clusters.
