## Common questions

### Do I need to open network ports for basic local use of the Sequential Thinking MCP server?

No. It normally listens on stdin/stdout rather than a web address, so local use does not require opening network ports.

### How can I reduce memory usage during long thinking sessions?

Set the MAX_HISTORY_SIZE environment variable, for example to 1000, to limit how much thinking history the server tracks. This matters for long multi-step sessions because a large history can consume more memory.

### How do I disable logging of thought information?

Set the DISABLE_THOUGHT_LOGGING environment variable to true.
