OpenFGA (Fine-Grained Auth)

What is the 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.

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.

Why AutoGen?

AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use OpenFGA (Fine-Grained Auth) tools. Connect 16 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.

  • Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use OpenFGA (Fine-Grained Auth) tools to solve complex tasks

  • Role-based architecture lets you assign OpenFGA (Fine-Grained Auth) tool access to specific agents. a data analyst queries while a reviewer validates

  • Human-in-the-loop support: agents can pause for human approval before executing sensitive OpenFGA (Fine-Grained Auth) tool calls

  • Code execution sandbox: AutoGen agents can write and run code that processes OpenFGA (Fine-Grained Auth) tool responses in an isolated environment

FAQ

Frequently asked questions

01

How can I check if a specific user has access to a resource?

You can use the check_relation tool. Provide the store ID and the relationship details (user, relation, and object) to get an immediate boolean response on whether the access is permitted.

02

Can I see the history of changes made to relationship tuples?

Yes, the read_changes tool allows you to retrieve the changelog of relationship tuples for a specific store, optionally filtered by object type.

03

How do I define a new authorization model?

Use the write_authorization_model tool. You will need to provide the store ID, the schema version, and a JSON array of type definitions that describe your relations.

04

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call OpenFGA (Fine-Grained Auth) tools during their conversation turns.

05

Can different agents have different MCP tool access?

Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.

06

Does AutoGen support human approval for tool calls?

Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
