What is the Cerbos MCP Server?
Connect your Cerbos instance to any AI agent to manage complex authorization policies through natural language conversation.
What you can do
- Permission Evaluation — Use
check_resourcesto instantly verify if a principal can perform specific actions on resources based on your policies. - Query Planning — Generate AST-based query plans with
plan_resourcesto filter database results according to user permissions. - AuthZEN Compliance — Leverage standardized access requests using
authzen_evaluationandauthzen_evaluationstools. - System Monitoring — Check instance health and build metadata using
get_server_infoandget_authzen_config.
How it works
- Subscribe to this server
- Provide your Cerbos instance base URL (e.g.,
http://localhost:3592) - Start auditing and testing your access control logic directly from your chat interface
Who is this for?
- Software Engineers — debug complex RBAC/ABAC policies without manual API calls
- Security Auditors — verify permission logic across different roles and resource attributes
- DevOps Teams — monitor Cerbos instance metadata and configuration status
Built-in capabilities (6)
Single action evaluation using the AuthZEN entity model
Supports execute_all, deny_on_first_deny, and permit_on_first_permit semantics. Batch evaluation of multiple access requests using AuthZEN
This is a read-only evaluation. Evaluates permissions for a principal on a set of resources
Returns endpoint URLs for the AuthZEN APIs
Returns the version and build details of the Cerbos instance
Produces a query plan for obtaining a list of resources a principal is allowed to access
Why AutoGen?
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use Cerbos tools. Connect 6 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 tools to solve complex tasks
- —
Role-based architecture lets you assign Cerbos 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 tool calls
- —
Code execution sandbox: AutoGen agents can write and run code that processes Cerbos tool responses in an isolated environment
Cerbos in AutoGen
Cerbos and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Cerbos to AutoGen through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for Cerbos in AutoGen
The Cerbos MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 6 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in AutoGen only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Cerbos for AutoGen
Every tool call from AutoGen to the Cerbos MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I check if a specific user has permission to access a resource?
Yes. Use the check_resources tool by providing the principal (user) details and the resource information. The agent will return an evaluation of allowed or denied actions.
How do I generate a filter for my database based on user permissions?
Use the plan_resources tool. It produces a query plan (AST) that you can use to construct database queries, ensuring users only see records they are authorized to access.
Is it possible to verify the Cerbos server version via AI?
Yes, the get_server_info tool retrieves the version, build date, and commit hash of your connected Cerbos instance.
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 tools during their conversation turns.
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.
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.
