## What is Slack MCP?

Slack MCP is a **remote Model Context Protocol server** hosted by InsightfulPipe. Access channels, messages, users, conversations, and search across your Slack workspace.

## Installation

### Claude

1. Copy the MCP Server URL: `https://slack.insightfulmcp.com/`
2. Open [Claude Connectors Settings](https://claude.ai/settings/connectors)
3. Scroll to the bottom and click **Add custom connector**
4. Paste the URL and click **Add**
5. Click **Connect** and sign in to InsightfulPipe if asked. Claude then lists the connector as connected.

### ChatGPT

Custom MCP servers are added through ChatGPT's **Developer mode**. Availability depends on your ChatGPT plan, and workspace admins may need to allow it.

1. Turn on **Developer mode** in ChatGPT settings
2. Create a new app for a remote MCP server and paste the URL: `https://slack.insightfulmcp.com/`
3. Sign in to InsightfulPipe if asked. The connection finishes as soon as you are signed in.

See OpenAI's guide: [Developer mode and MCP apps in ChatGPT](https://help.openai.com/en/articles/12584461-developer-mode-and-mcp-apps-in-chatgpt)

    }

## Control What Your AI Can Do

You decide what AI agents can do with each connected account:

- **Turn individual actions on or off** for every connected account, so agents only see the actions you allow.
- **Connect as Read-only or Read & Write.** A read-only connection can only enable read actions.
- **Destructive actions stay off by default.** Actions such as deletes are disabled until an admin enables them.
- **Team access per account.** Restricted team members only use the accounts they are granted, with the read actions enabled on them.

## Usage Examples

```
"Summarize the last day of messages in #marketing"
```

```
"Post the weekly report to #general"
```

```
"Remind me tomorrow at 9am to review campaigns"
```
