Connect an AI assistant to a Slack workspace to read and post messages on your behalf.

Lets an AI assistant read channel history and post messages in a Slack workspace — useful for having it summarize a channel's activity, draft a message for you to review, or (if you grant posting) send updates on your behalf.
```json
{
"mcpServers": {
"slack": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-slack"],
"env": {
"SLACK_BOT_TOKEN": "<YOUR_BOT_TOKEN>",
"SLACK_TEAM_ID": "<YOUR_TEAM_ID>"
}
}
}
}
```
Requires creating a Slack app and bot token with specific scopes (read history, post messages, etc.) in your workspace's app settings first — grant only the scopes you actually need, and be aware that a bot token with posting rights means the assistant can send real messages other people will see, so review anything it drafts before it's able to send unsupervised.
Check the server's current docs for the exact scopes it needs, since Slack's own API scope names change independently of this server.
