What Auth0 for AI Agents does

Provides OAuth 2.1 and OpenID Connect authorization for MCP servers, including discovery, client registration, resource-scoped tokens, and token exchange.

Why teams reach for it: Developers use it to add the MCP spec's OAuth 2.1 authorization to their server without building an authorization server themselves.

Worth knowing

It implements OAuth 2.1, with PKCE required, and CIMD and DCR client registration. It federates with Google and holds an upstream token vault for third-party credentials.

Who can connect, and what may they do?

Authorization & identity tools control who — or which AI agent — is allowed to connect, and what they're allowed to do once connected.
