Cerbos (Access Control)

What is the Cerbos (Access Control) MCP Server?

Connect your Cerbos instance to any AI agent to streamline authorization management and policy auditing through natural language.

What you can do

  • Permission Checks — Use check_resources to evaluate if a principal (user) has the rights to perform specific actions on resources.
  • Query Planning — Generate AST query plans with plan_resources to filter database results based on complex authorization logic.
  • Policy Management — List, retrieve, add, or delete policies (RBAC/ABAC) using the Admin API tools like list_policies and add_policy.
  • Schema & Auditing — Inspect resource schemas and review access logs with list_auditLogs to ensure compliance.
  • Health & Metrics — Monitor your PDP (Policy Decision Point) status with get_health and get_metrics directly from the chat.

How it works

  1. Subscribe to this server
  2. Enter your Cerbos PDP URL and Admin credentials (if required for policy management)
  3. Start auditing and managing your access control logic from Claude, Cursor, or any MCP client

Who is this for?

  • Security Engineers — quickly audit existing policies and verify permission logic without manual API calls
  • Backend Developers — test authorization scenarios and generate database filter plans during development
  • Compliance Officers — retrieve audit logs and policy definitions to ensure organizational security standards

Why AutoGen?

AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use Cerbos (Access Control) tools. Connect 19 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 Cerbos (Access Control) tools to solve complex tasks

  • Role-based architecture lets you assign Cerbos (Access Control) 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 Cerbos (Access Control) tool calls

  • Code execution sandbox: AutoGen agents can write and run code that processes Cerbos (Access Control) tool responses in an isolated environment

FAQ

Frequently asked questions

01

Can I test if a specific user has access to a resource without writing code?

Yes. You can ask the agent to use the check_resources tool by providing the principal (user) details and the resource you want to check. The agent will return the allowed or denied status based on your Cerbos policies.

02

How do I view all the authorization policies currently loaded in my Cerbos server?

Simply ask the agent to 'list all policies'. It will invoke the list_policies tool (requires Admin credentials) and display the IDs of all active policies in your environment.

03

Can the AI help me generate filters for my database based on permissions?

Yes, by using the plan_resources tool. The agent will generate a query plan (AST) that describes the conditions under which a user is allowed to access resources, which you can then apply to your database queries.

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 Cerbos (Access Control) 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.
