What is the Permit.io MCP Server?

Connect your Permit.io account to any AI agent to manage your application's authorization layer through natural language. This server allows you to evaluate permissions, manage your authorization schema, and handle user facts without touching code.

What you can do

Policy Evaluation — Instantly check if a user is permitted to perform specific actions on resources using the check_permission tool.
Schema Management — Create resources, define roles, and assign permissions dynamically to build RBAC or ReBAC (Relationship-Based Access Control) structures.
Fact Management — Provision users and tenants directly into your authorization environment to keep your permission data in sync.
AuthZen Compatibility — Use standardized AuthZen evaluation tools for interoperable access control checks.
ReBAC Relations — Define complex relationships between resources to handle hierarchical or ownership-based permissions.

How it works

Subscribe to this server
Enter your Permit.io API Key (and optionally your PDP URL)
Start managing your authorization policies from Claude, Cursor, or any MCP-compatible client

Who is this for?

Developers — Quickly test authorization logic or provision test users and roles without leaving the IDE.
Security Engineers — Audit and update access control policies through a conversational interface.
Product Managers — Define new feature permissions and roles as part of the product requirements workflow.

FAQ

Frequently asked questions

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

Use the check_permission tool. You need to provide the user identifier, the action (e.g., 'read'), and the resource object (including type and tenant). The agent will query your PDP and return the authorization decision.

Can I create new roles and assign permissions to them using this server?

Yes. You can use create_role to define a new role in your schema and then use assign_permissions_to_role to specify exactly what that role is allowed to do within a project and environment.

Does this integration support AuthZen standards?

Yes, it includes several tools like authzen_access_evaluation and authzen_bulk_evaluations to perform authorization checks following the AuthZen specification.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
