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.
