# Tool Connections

> Connect external accounts so your agents can act on your behalf.

Many tools — like email, messaging, or CRM integrations — need access to one of your accounts on that service. A **tool connection** is that authorized link. This page walks through connecting one.

## What a connection is

When you connect a tool, you authorize the platform to act on your behalf in that external service — for example, to send messages from your account or read data you have access to. The authorization is stored securely, and you can revoke it at any time.

## Connecting an account

<Steps>
  <Step title="Find the integration">
    On the [Tools](/agents-models-tools/tools) page, locate the integration under **Available Tools to Add** and click **Connect**.
  </Step>

  <Step title="Sign in to the service">
    You're taken to the external service's own sign-in page. Log in with the account you want to connect.
  </Step>

  <Step title="Review and authorize">
    The service shows what access is being requested. Review it and approve.
  </Step>

  <Step title="Return to the platform">
    You're brought back automatically. The tool now appears under **My Tools** with a connected status.
  </Step>
</Steps>

<Note>
  You sign in on the external service's own page — the platform never sees your password for that service.
</Note>

## Using a connected tool

Once connected, attach the tool to an agent like any other. The agent uses your connection when it calls that tool during a run. See [Configuring agents](/building-workflows/configuring-agents#tools).

## Managing connections

From the tool's card under **My Tools**, you can **Disconnect** — this revokes the link to your account, and the tool stops working.

If a connection expires or stops working, connect the integration again from **Available Tools to Add** to restore access.

<Warning>
  Disconnecting a tool that's attached to a deployed workflow will cause that workflow's runs to fail when they try to use it. Check where a tool is used before disconnecting.
</Warning>
