Mcp Sequentialthinking Tools

mcp-sequentialthinking-tools

[](https://viteplus.dev) [](https://vitest.dev)

A lightweight MCP server for recording sequential reasoning steps. It is a scratchpad with history, branching, revision metadata, and optional validation for model-authored tool plans.

It does **not** discover your other MCP tools and it does **not** choose tools for the model. If you pass `available_tools` and `recommended_tools`, the server validates that the recommended names exist and stores the step.

Why use it?

Use this when a task benefits from explicit, inspectable reasoning:

• breaking a messy problem into steps;
• revising or branching a plan;
• keeping a small reasoning history by session;
• validating tool-plan names against a supplied tool list;
• clearing or inspecting reasoning history during a long agent run.

Do not use it for trivial requests. It adds overhead.

Tools

`sequentialthinking_tools`

Records one thought.

Required parameters:

• thought — current reasoning step
• thought_number — current step number
• total_thoughts — current estimate; automatically raised if lower than thought_number
• next_thought_needed — whether another thought is needed

Optional parameters:

• session_id — history bucket; defaults to default
• is_revision, revises_thought
• branch_from_thought, branch_id
• needs_more_thoughts
• available_tools — array of tool names or { name, description } objects
• recommended_tools — model-authored recommendations to validate/store
• remaining_steps — short list of upcoming steps

Example:

{
	"session_id": "svelte-debug",
	"thought": "First in
