---title: Connectionsdescription: "A connection is a configured instance of an integration. One integration can have many connections."--- A **connection** is a configured instance of an [integration](/concepts/integrations).A single integration can have many connections: the same API authenticated for twodifferent accounts, say. A connection doesn't have to be authenticated: public APIs and public MCP servers can beconnected with no credentials. When credentials are required, Executor stores them andapplies them on every tool call, so the agent never handles them directly.
