You can use the Sequential Thinking MCP Server to guide problem solving by breaking complex tasks into manageable steps and receiving confidence-rated tool recommendations for each stage. This server helps you plan, execute, and track your approach, adapting as you revise thoughts and explore branches.

How to use

You interact with the Sequential Thinking MCP Server through your MCP client. Each thinking step you submit returns a recommended set of tools for the current task, along with a rationale, a confidence score, and a suggested execution order. Use the results to structure your approach, verify information, and decide which tools to run next. You can create branches to explore alternate strategies and revise earlier thoughts as new information comes in. The server tracks progress, expected outcomes, and remaining steps to help you stay on a productive path.

How to install

Prerequisites: ensure you have Node.js and a package manager available on your system. You will use a client to interact with the MCP server and run the included commands.

# Install prerequisites if needed (example for Node.js via your system's package manager)
# Node.js should be available as node and npm or pnpm

# Install the MCP client tooling if required by your setup (example)
pnpm install -g pnpm

# Run the server in development mode if you are using a local setup (example placeholder)
pnpm install
pnpm build
pnpm dev

Configuration and starting points

You can run the MCP server locally using standard command patterns shown in supported environments. The following configurations demonstrate both a direct local execution via npx and a WSL-based approach for Windows environments.

{
  "mcpServers": {
    "sequentialthinking": {
      "command": "npx",
      "args": ["-y", "mcp-sequentialthinking-tools"]
    }
  }
}

Tools and API access

The server exposes a single MCP tool named sequentialthinking_tools that orchestrates dynamic problem-solving steps. It accepts a set of parameters describing your current thought, whether you need more thoughts, and context about the current and upcoming steps. The tool provides a structured response with recommended tools, confidence scores, and next-step guidance.

Additional usage notes

If you are using a Windows Subsystem for Linux (WSL) setup, you can run the MCP server through a WSL command chain that invokes npx inside the Linux environment. This lets you access the same MCP functionality from your Windows machine via the WSL shell.

Troubleshooting tips

- Ensure your MCP client is correctly configured to point to the local or remote MCP server as shown in the configuration examples. - Check that Node and the chosen package manager are installed and accessible in your environment. - If tool recommendations seem misaligned, verify the current step’s description and expected outcome, then consider revising previous thoughts or branching to an alternative approach.

Notes

The MCP server described here provides tools with configurable parameters and supports progress tracking, branching, and revision of thoughts to adapt to evolving problem-solving needs.

Security and best practices

Operate the MCP server in a secure environment. Do not expose internal tool endpoints to untrusted networks. Validate tool outputs before acting on recommendations, especially when executing code or altering system configurations.

Development and contribution

Development and contribution instructions are available for contributors who want to extend the server capabilities, add tools, or improve the reasoning workflow.
