About OpenFGA (Fine-Grained Auth) MCP Server
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.
LlamaIndex agents combine OpenFGA (Fine-Grained Auth) tool responses with indexed documents for comprehensive, grounded answers. Connect 16 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.
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.
The OpenFGA (Fine-Grained Auth) MCP Server exposes 16 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
