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. Executor runs tool calls in a sandbox, so the agent can never access the credentials.
