Online & Connectors is where you connect Slack so Chat and Personas can use it, and where you review recent tool actions. Click your name at the bottom of the sidebar, then **Settings**, then **Online & Connectors**.

## How tools work

A local model can answer from what you type. Tools let it also look things up or take an action outside the chat.

MCP (Model Context Protocol) is the shared format for those tools. When Slack is connected, Slack tools are available to the model. In Chat, the model can pick a tool that fits your request. webAI runs that call on this computer and logs it under **Recent tool actions**.

You do not pick the tool name yourself. You ask in Chat, and the model chooses when a tool helps. You can also assign a tool to a Persona so that Persona can use it. See [Personas](/using-webai/personas).

## Disconnect Slack

Open the connected Slack row, then disconnect it. Confirm **Disconnect**. The saved Slack connection is removed. Chat can no longer use Slack tools until you connect it again.

## Action history

**Recent tool actions** lists tool attempts on this computer. Each row shows when it ran, the tool name, whether it was a read or a write, and the result. Slack reads show as **Read**. Posts and replies show as **Write**.

Other tools can appear in this list too. For example, a web search can log here without a Slack connection.

Click **Clear** to empty the list. That does not disconnect Slack.
