Claude Code gets stuck when using sequentialthinking

[j4redux]

Describe the bug
A clear and concise description of what the bug is.

This bug was first reported to the Claude Code repo where I was told this is an issue with sequentialthinking.

When using Claude Code, after using the sequentialthinking MCP server once, I'm forced to use sequentialthinking in that session going forward unless I clear the context or restart the session.

If I tell Claude Code to stop using sequentialthinking, I can't continue the session.

To Reproduce
Steps to reproduce the behavior:

1. Using sequentialthinking in Claude Code
2. Try to move forward without sequentialthinking, it will continue to use it instead of other tools (not super consistent)

Expected behavior
A clear and concise description of what you expected to happen.
After using sequentialthinking, it's not used unless prompted to do so.
