## AI overview

The article explains how Connections in Managed Deep Agents stores credentials in a LangSmith workspace and retrieves them at runtime. It covers shared agent-owned secrets and per-caller credentials through OAuth, including examples for Tavily, GitHub, and Linear MCP. The setup handles authorization and missing grants, allowing agents to act with each caller's identity without implementing OAuth callback or token-management flows in the project.
