Sequential Thinking

# 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 ```json { "mcpServers": { "sequential-thinking": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-sequential-thinking" ] } } } ``` #### docker ```json { "mcpServers": { "sequentialthinking": { "command": "docker", "args": [ "run", "--rm", "-i", "mcp/sequentialthinking" ] } } } ``` To disable logging of thought information set env var: `DISABLE_THOUGHT_LOGGING` to `true`.

Open the Command Palette (`Ctrl + Shift + P`) and run `MCP: Open User Configuration`. This will open your user `mcp.json` file where you can add the server configuration. **Method 2: Workspace Configuration** Alternatively, you can add the configuration to a file called `.vscode/mcp.json` in your workspace. This will allow you to share the configuration with others. > For more details about MCP configuration in VS Code, see the [official VS Code MCP documentation](https://code.visualstudio.com/docs/copilot/customization/mcp-servers). For NPX installation: ```json { "servers": { "sequential-thinking": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-sequential-thinking" ] } } } ``` For Docker installation: ```json { "servers": { "sequential-thinking": { "command": "docker", "args": [ "run", "--rm", "-i", "mcp/sequentialthinking" ] } } } ``` ### Usage with Codex CLI Run the following: #### npx ```bash codex mcp add sequential-thinking npx -y @modelcontextprotocol/server-sequential-thinking ``` ## Building Docker: ```bash docker build -t mcp/sequentialthinking -f src/sequentialthinking/Dockerfile . ``` ## License This MCP server is licensed under the MIT License.
