# What can a connector see and do?

A connector is a service run by someone other than Bluedeer, so check what you connect, what the assistant sends to it, and what it can change without asking.

A connector is a third-party service. Bluedeer checks the address and the tools, but it does not control what the service does with the information it receives.

## What a connector receives

- **Custom connectors.** When the assistant uses one of its tools, it sends that tool the arguments for the call. The service's answer comes back into your chat.
- **Built-in services.** The assistant can read what your sign-in allows. For Gmail, that means your mail. For Google Drive, your files. For Notion, only the pages and databases you shared with the Bluedeer integration. For Slack, the channels and people your Slack account can see.

Before you approve a sign-in, the card lists the permissions it asks for. Read that list before you continue.

## Whose sign-in is used

- **Built-in services** use your own sign-in. Other members cannot use it, and it is not used in other workspaces.
- **Custom connectors** that use a shared sign-in, or an API token, are used by everyone in the workspace. An admin who signs in to a custom connector sets up the connection for the whole workspace.

## Actions that run without asking

Some actions run as soon as the assistant calls them, with no approval card:

- Google Calendar: creating, changing and deleting events.
- Google Drive: moving a file to the trash, and sharing a file with an email address.
- Google Sheets: updating cells, appending rows, sorting and renaming.
- Google Docs: inserting text.
- Slack: sending a text message.
- Google Apps Script: replacing a project's code, which overwrites all of its files.

The **Action confirmations** setting does not apply to the actions above. For a custom connector, you can set its tools to **Asks first**. Read [How do I approve, allow or stop an action from a connector?](https://support.bluedeer.ai/connectors/general/approve-connector-actions.md).

## Good habits

- Connect only the services you trust and need.
- Turn off or remove a connector you no longer use.
- Look at the tool list of a custom connector, and turn off tools you do not need.
- Keep **Asks first** on tools that change data.
