About Sequential Thinking MCP Server - Forked to Support SSE

An MCP server that exposes a structured, revisable thinking tool for step-by-step problem solving. Its process supports branching and changing the expected number of steps as analysis develops.

Key features

  1. 01Break problems into steps
  2. 02Revise earlier thoughts
  3. 03Branch into reasoning paths
  4. 04Adjust thought count dynamically
  5. 05Form and verify hypotheses

Use cases

  1. 01Analyze problems with unclear scope
  2. 02Plan designs with room for revision
  3. 03Explore alternative reasoning paths

MCP support

Exposes the sequential_thinking tool to MCP clients, with inputs for thought steps, revisions, branching, and whether more steps are needed.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "sequentialthinking": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "build"
      ]
    }
  }
}
Run commanddocker run -i --rm build

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Tools

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Sequential Thinking MCP Server - Forked to Support SSE

Forked from https://github.com/modelcontextprotocol/servers/tree/main/src/sequentialthinking

Sequential Thinking MCP Server

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process.

Features

  • Break down complex problems into manageable steps
  • Revise and refine thoughts as understanding deepens
  • Branch into alternative paths of reasoning
  • Adjust the total number of thoughts dynamically
  • Generate and verify solution hypotheses

Tool

sequential_thinking

Facilitates a detailed, step-by-step thinking process for problem-solving and analysis.

Inputs:

  • thought (string): The current thinking step
  • nextThoughtNeeded (boolean): Whether another thought step is needed
  • thoughtNumber (integer): Current thought number
  • totalThoughts (integer): Estimated total thoughts needed
  • isRevision (boolean, optional): Whether this revises previous thinking
  • revisesThought (integer, optional): Which thought is being reconsidered
  • branchFromThought (integer, optional): Branching point thought number
  • branchId (string, optional): Branch identifier
  • needsMoreThoughts (boolean, optional): If more thoughts are needed

Usage

The Sequential Thinking tool is designed for:

  • Breaking down complex problems into steps
  • Planning and design with room for revision
  • Analysis that might need course correction
  • Problems where the full scope might not be clear initially
  • Tasks that need to maintain context over multiple steps
  • Situations where irrelevant information needs to be filtered out

Configuration

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

npx

        "-y",
        "@modelcontextprotocol/server-sequential-thinking"
      ]
    }
  }
}
docker
{
  "mcpServers": {
    "sequentialthinking": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "mcp/sequentialthinking"
      ]
    }
  }
}

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
