Prerequisites

- Choose your workspace and approve the requested scopes.
Using with AI clients
- Dedicated endpoint:
POST /mcp/slack - Private gateway:

Troubleshooting
- Missing channels — the bot/user token may not have access to private channels; invite the app or adjust scopes.
- Reconnect required — revoke and reconnect if the workspace admin changed app permissions.
