TL;DR

The most likely fix is to stop the running browser instance or use a different userDataDir to resolve the McpToolCallError caused by a browser already running.

Guidance

• Stop the running browser instance before attempting to run multiple browser instances.
• Use the --isolated flag to run multiple browser instances.
• Check the userDataDir configuration to ensure it is not being used by another process.
• Verify that the userDataDir path is correct and has the necessary permissions.

Example

No code snippet is provided as the issue is related to configuration and process management.

Notes

The issue seems to be related to the McpToolCallError exception, which is caused by a browser already running. The error messages suggest using a different userDataDir or stopping the running browser instance. However, the content was truncated, and some details might be missing.

Recommendation

Apply workaround: Stop the running browser instance or use a different userDataDir to resolve the issue, as the error messages suggest that this is the root cause of the problem.
