Permit.io MCP Gateway

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.
