How do I find my Slack Bot Token?

Log in to the [**Slack App Console**](https://api.slack.com/apps), select your App, go to **OAuth & Permissions**, and copy the 'Bot User OAuth Token'. Paste it below.

Can the agent check if a user is active?

Yes. Use the `get_presence` tool providing the User ID. Your agent will return the real-time presence status (active or away) for that specific user.

Is it possible to retrieve message history via the agent?

Yes. The `get_history` tool allows your agent to fetch recent messages from any channel, helping you audit conversations or monitor specific updates.
