Jess Yan explains that Anthropic agents can be connected to third-party systems, such as internal databases, through MCP (Messaging and Communication Protocol). MCP provides a standardized way to communicate with external services and includes an authentication layer for secure access.

“MCP exposes a standardized way to communicate to external services and it includes an authentication layer in front.”
“So that allows you to safely access these internal services that you might not want just anyone to access.”
