Unable to connect to Atlassian MCP server on macOS machine

Cause

This issue occurs when Katalon Studio (KS) is upgraded from an older version to a newer version, causing the application signature to change and preventing access to data stored in the OS secure storage.

Remedy

You need to delete the file containing the MCP token, then set up the connection to the MCP server again.

1. Locate the .katalon folder on your machine: /Users/<user_name>/.katalon.

Tip: Since .katalon is a hidden folder, use Command+Shift+. to view the folder.

1. In the studioassist folder, delete the session.properties file.
2. Go to Katalon Studio and add the MCP server again.
