Sequential Thinking Working Notes
The Sequential Thinking MCP server enables structured problem-solving by organizing thoughts through defined cognitive stages (Problem Definition, Research, Analysis, Synthesis, Conclusion) and provides tools to track thought progression, identify connections between related thoughts, monitor progress, and generate summaries. It stores thinking sessions persistently with thread-safe file access, supports data import/export, and includes robust error handling and type validation through Pydantic models. The server solves the problem of managing complex reasoning processes by breaking them into sequential, trackable steps and providing visibility into the overall thinking progression.

Readme
MCP Sequential Thinking
A local MCP server for working notes you can resume: evidence, decisions, risks and next actions for a difficult task, stored durably in SQLite and readable after any restart. It records what the caller writes; it does not generate, judge or improve reasoning, and it never asks for hidden chain-of-thought.
