Sequential Thinking MCP Server

An MCP server that provides a structured, step-by-step tool for breaking down complex problems, allowing for branching, revision, and refinement of the reasoning process.

Overview

This server implements the Sequential Thinking tool via the Model Context Protocol (MCP). It's designed for dynamic problem-solving where the full scope may not be initially clear, enabling you to plan, analyze, and correct course over multiple steps while maintaining context.

Key Features

• Step-by-Step Reasoning: Breaks down complex tasks into manageable thought steps.
• Non-Linear Workflow: Supports branching from any point in the thinking process.
• Revision & Correction: Allows revising or reconsidering previous thoughts.
• Context Management: Maintains the problem's context across multiple steps.
• Scope Handling: Useful for tasks where the total number of required steps is unknown upfront.

How to Use

Connection

MCP clients connect to the server at:

https://mcp-servers--sequentialthinking-mcp-server.apify.actor/mcp

Client Configuration

Add this server configuration to your MCP client:

{
  "mcpServers": {
    "sequentialthinking": {
      "url": "https://mcp-servers--sequentialthinking-mcp-server.apify.actor/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_APIFY_TOKEN"
      }
    }
  }
}

Note: Replace YOUR_APIFY_TOKEN with your Apify API token from the Apify Console.

Input/Output

The server provides one main tool: sequential_thinking.

Tool: sequential_thinking

Facilitates a detailed, iterative thinking process.

Primary Inputs:
* thought (string): The content of the current thinking step.
* nextThoughtNeeded (boolean): Indicates if another thought step is required.
* thoughtNumber (integer): The sequential number of the current thought.
* totalThoughts (integer): The estimated total number of thoughts needed.

Optional Inputs for Advanced Control:
* isRevision (boolean): Set to true if this step revises previous thinking.
* revisesThought (integer): Specifies which thought number is being reconsidered.
* branchFromThought (integer): The thought number from which a new branch originates.
* branchId (string): An identifier for the branch.
* needsMoreThoughts (boolean): Signals that the initial estimate was insufficient and more thoughts are required.

Use Cases:
* Planning and design with room for iteration.
* Analysis that may require mid-process correction.
* Filtering out irrelevant information over a multi-step process.
* Tasks where the problem's complexity unfolds gradually.
