Enterprise AI just got a lot more secure. Anthropic launched a beta of "Enterprise Managed Auth" in Claude, so you can now connect Claude seamlessly to MCP servers through your enterprise IdP like Okta!

Now employees no longer have to connect MCP servers manually and wait for a series of OAuth and login prompts. Once you log in to Claude from Okta, all the preconfigured MCP servers are already connected! It's not every day you get to improve both usability and security!

This is an application of the Cross App Access pattern, defined in the Identity Assertion JWT Authorization Grant being standardized in the OAuth working group at the IETF.

Seeing adoption from a massive player like Claude is a huge validation of the effort! It's been fantastic to work with the folks at Anthropic over the past year on this Paul Carleton and Den Delimarsky. And of course this wouldn't be possible without the collaboration with my co-authors on the spec Karl McGuinness and Brian Campbell!
