# Connect

> The ways to call a connector's actions — from an agent or directly.

To start connecting your agents, a connector needs a [connector profile](/gateway/quickstart#setup-connector-profile) and a [linked account](/gateway/quickstart#link-account). With an account linked, the actions are ready to use.

Attach them to your [agent](#attach-to-your-agent), or use one of the [protocols and SDKs](#protocols--sdks) that fits your stack. All share the same actions and authentication for simplicity.

## Attach to your agent

Pick your agent to get started — each connects over MCP:

## Test your actions

Try a connector's actions before wiring them into your product. Pick the tool that fits what you're checking:
