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_resources to instantly verify if a principal can perform specific actions on resources based on your policies.
Query Planning — Generate AST-based query plans with plan_resources to filter database results according to user permissions.
AuthZEN Compliance — Leverage standardized access requests using authzen_evaluation and authzen_evaluations tools.
System Monitoring — Check instance health and build metadata using get_server_info and get_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)

authzen_evaluation

Single action evaluation using the AuthZEN entity model

authzen_evaluations

Supports execute_all, deny_on_first_deny, and permit_on_first_permit semantics. Batch evaluation of multiple access requests using AuthZEN

check_resources

This is a read-only evaluation. Evaluates permissions for a principal on a set of resources

get_authzen_config

Returns endpoint URLs for the AuthZEN APIs

get_server_info

Returns the version and build details of the Cerbos instance

plan_resources

Produces a query plan for obtaining a list of resources a principal is allowed to access

Why VS Code Copilot?

GitHub Copilot Agent mode brings Cerbos data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 6 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.

—
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
—
Project-scoped MCP configs (.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access
—
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
—
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

FAQ

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.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
