Slack

Lets an agent read from and write to channels in a Slack workspace you control. Connect your Slack workspace once via OAuth - no token to paste.

What it can do​

  • List channels and users
  • Read recent messages in a channel or thread
  • Post messages and thread replies
  • Add and remove reactions

How to get credentials​

Slack uses OAuth - there's no token to copy or custom app to build.

  1. In FlyMyAI, open the Slack MCP and click Connect Slack to start the setup flow.
  2. A Slack authorization screen opens. Pick the target workspace, sign in, and click Allow to approve the requested scopes.
  3. You're redirected back to FlyMyAI; the tool flips to Configured.

The agent posts as the FlyMyAI Slack app. For any channel the agent should read or post in that it isn't already in, invite it with /invite @FlyMyAI in that channel.

Fields to fill in FlyMyAI​

No fields - the Connect Slack OAuth flow stores the workspace token automatically. To switch workspaces, remove the tool and reconnect.

Troubleshooting​

  • not_in_channel - invite the app to the channel with /invite @FlyMyAI.
  • OAuth denied - approve the FlyMyAI app on the Slack consent screen; a workspace admin may need to allow third-party apps or approve the install.
  • Need more access - reconnect via Connect Slack to re-run the OAuth flow with the current scopes.
