Instead of implementing OAuth2 flows, token caching, and consent management in every agent, developers configure auth once at the connection level. Foundry then handles token acquisition, refresh, and isolation server-side. The feature supports multiple auth types including end-user OAuth2 delegation, agentic identity, managed identity, API keys, and anonymous access. Toolboxes also provide built-in RAI guardrails to screen tool inputs/outputs and support bring-your-own gateway for rate limiting and logging. A three-step setup covers creating a connection with auth type, building a versioned toolbox with tools, and consuming it from an agent via a single MCP endpoint. ## Full article daily.dev links to this article rather than hosting it.
