Slack notifications sent to incorrect or random channel

When workflows send notifications to Slack, messages are delivered to incorrect or randomly selected groups instead of the configured destination.

Steps to reproduce:

  1. Configure a workflow with Slack notification

  2. Trigger the workflow manually or automatically

  3. Check Slack channels for the notification

Expected result:
Notifications should be sent to the user-selected Slack channel or direct message.

Actual result:
Messages are sent to an unintended or random Slack group.

Impact:
Causes confusion and potential information leakage.

This is an issue with MCP. If you use HTTP mode for the Slack step, it should work perfectly fine.

In the meanwhile, we will look into the MCP integration

Thanks for the update. I’ve tested using HTTP mode for the Slack step and the notifications are now going to the correct channel.

Thanks for following up. Happy to hear it’s now working for you :+1:t3:
