The server exposes a single tool that the model calls once per reasoning step, numbering each thought and declaring whether another step is needed. A step can be marked as a revision of an earlier one, or as a branch that explores an alternative path, so a wrong turn is corrected instead of silently carried forward. It holds no data of its own and needs no credentials; setting DISABLE_THOUGHT_LOGGING keeps the intermediate steps out of the logs.
