Reference MCP server with one tool for step-by-step problem solving that supports revising thoughts and branching.

The sequential_thinking tool takes the current thought, whether another is needed, the thought number and an estimated total, plus optional fields for revisions and branches. The README lists breaking down problems, revising thoughts as understanding grows, and adjusting the total number of thoughts as uses.

The npm package is @modelcontextprotocol/server-sequential-thinking.
