About 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.
LlamaIndex agents combine Permit.io tool responses with indexed documents for comprehensive, grounded answers. Connect 18 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.
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.
The Permit.io MCP Server exposes 18 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
