--- title: Connections description: "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 two different accounts, say. A connection doesn't have to be authenticated: public APIs and public MCP servers can be connected with no credentials. When credentials are required, Executor stores them and applies them on every tool call, so the agent never handles them directly.
