MCP lets AI agents connect to your tools, but its built-in auth is limited. There's no fine-grained authorization, no governance, and no connection to your existing IdP infrastructure. Permit MCP Gateway is a zero-trust proxy that adds what's missing to any MCP server without touching its code. Swap one URL and every tool call gets OAuth authentication, Zanzibar-style authorization, consent screens, and full decision logging. No SDK to install. No agents to rewrite. Works with any MCP server.

Every application requires managing permissions, and complexity is constantly on the rise. Permit.io provides permissions as a service (ReBAC, Policy as Code, APIs, and customer-facing UI), so developers can check this as done and focus on their core product.

“Permit Share-If” is a suite of prebuilt, embeddable UI components that make access sharing in applications a breeze. Designed to provide fully functional access control, they make delegating permission management to your users simple and safe.

Permit.io AI Access Control brings fine-grained authorization (FGA) to AI workflows, ensuring AI models interact safely with sensitive data, external APIs, and users - all without developers having to build this from scratch
