About Sequential Thinking MCP Server

It records and organizes a thinking process through defined stages — it does not evaluate, generate, or improve the reasoning itself; that stays with whatever model is calling it.

Features

  • Structured Thinking Framework: Organizes thoughts through standard cognitive stages (Problem Definition, Research, Analysis, Synthesis, Conclusion), with warnings (or, in --strict-stages mode,…

  • Revisions & Branching: Revise earlier thoughts or fork alternative lines of reasoning, with revision- and branch-aware analysis and summaries

  • Thought Tracking: Records and manages sequential thoughts with metadata as a structured, typed audit trail (structured_content on every tool response)

  • Related Thought Analysis: Finds thoughts that are lexically similar to the current one, independent of stage, plus a separate same-tag/same-stage grouping — a categorical signal, not a claim of…

  • Progress Monitoring: Explicit mainline position, total recorded thoughts, branch count, and revision count — not a single ambiguous percentage

  • Summary Generation: Extracts the actual recorded thinking (per-stage excerpts, aggregated challenged assumptions, open branches, revision chains) alongside structural statistics — a deterministic…

  • Persistent Storage: Append-only JSONL session log with thread-safety and automatic crash recovery

  • Data Import/Export: Share and reuse thinking sessions

  • Extensible Architecture: Easily customize and extend functionality

  • Robust Error Handling: Protocol/validation errors (bad stage, duplicate thought number, path traversal) fail the call outright; execution errors the caller can adapt to come back as a normal tool…
