Compatible with every major AI agent and IDE
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_permissiontool. - 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.

Why Claude Code?
Claude Code registers Permit.io as an MCP server in a single terminal command. Once connected, Claude Code discovers all 18 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Permit.io data drives decisions without human intervention.
- —
Single-command setup:
claude mcp addregisters the server instantly. no config files to edit or applications to restart - —
Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks
- —
Claude Code runs headlessly, enabling unattended batch processing using Permit.io tools in cron jobs or deployment scripts
- —
Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features

Why teams choose Vinkius for Permit.io in Claude Code
The Permit.io 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 18 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Claude Code 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.

How Vinkius secures
Permit.io for Claude Code
Every tool call from Claude Code to the Permit.io MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
