How Vinkius protects your data

Can I set different limits for each virtual assistant on my team?

Absolutely. You have full control in our command center. You can create an AI agent that only "reads" data so the support team can answer questions, and another superpowered agent that can "edit" and "create" information exclusively for your operations team. Each AI gets exactly the level of access you allow.

Is there a risk of the AI "going crazy" and deleting important company data?

No. With Vinkius, the AI operates on "rails". It can only make the exact moves you authorized in the tool's settings. It cannot invent routes, access other networks in your company, or decide to delete random files. If the action isn't in the approved catalog, the attempt is blocked instantly.

Can I audit what my AI agents are doing with this integration?

Yes, Vinkius provides an immutable, HMAC-chained audit log. Every tool execution, payload, and response is tracked in real-time on your dashboard, giving you complete visibility into your agent's actions.

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.

Cerbos (Access Control) Capabilities for AI Assistants

Connect your AI agents and chatbots (Claude, ChatGPT, Cursor) with the Cerbos (Access Control) MCP server to manage operations across the following domains.

Cursor Copilot for authorization

Add authorization functionality to your custom chatbots. The Cerbos (Access Control) MCP handles the payload formatting required for ChatGPT and Claude to interface with developer tools endpoints.

Connecting rbac with Cursor

Connect the Cerbos (Access Control) server to enable rbac workflows. The integration provides structured schemas for Claude to mutate developer tools data.
