Channels and messaging.

OAuth 1 tools

Overview

Connect Slack workspaces so AI can read channels and send messages.

Prerequisites

  • A Slack workspace where you can install apps or authorize OAuth
  • A stackgate.ai account

Getting credentials

  1. Open Integrations → Slack in stackgate.ai.
  2. Click Activate, then Connect Slack.
  3. Choose your workspace and approve the requested scopes.

Using with AI clients

  • Dedicated endpoint: POST /mcp/slack
  • Private gateway: slack__* tools

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.

Available tools

  • list-channels-tool

    List Slack channels accessible to the connected workspace token.

MCP endpoint: https://stackgate.ai/mcp/slack (HTTP) or via the private gateway.
