# 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/mcp). 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" ] } } } ``` ## Building Docker: ```bash docker build -t mcp/sequentialthinking -f src/sequentialthinking/Dockerfile . ``` ## License This MCP server is licensed under the MIT License.

sequentialthinking

Description: A detailed tool for dynamic and reflective problem-solving through thoughts. This tool helps analyze problems through a flexible thinking process that can adapt and evolve. Each thought can build on, question, or revise previous insights as understanding deepens. When to use this tool: - 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 - Problems that require a multi-step solution - Tasks that need to maintain context over multiple steps - Situations where irrelevant information needs to be filtered out Key features: - You can adjust total_thoughts up or down as you progress - You can question or revise previous thoughts - You can add more thoughts even after reaching what seemed like the end - You can express uncertainty and explore alternative approaches - Not every thought needs to build linearly - you can branch or backtrack - Generates a solution hypothesis - Verifies the hypothesis based on the Chain of Thought steps - Repeats the process until satisfied - Provides a correct answer Parameters explained: - thought: Your current thinking step, which can include: * Regular analytical steps * Revisions of previous thoughts * Questions about previous decisions * Realizations about needing more analysis * Changes in approach * Hypothesis generation * Hypothesis verification - next_thought_needed: True if you need more thinking, even if at what seemed like the end - thought_number: Current number in sequence (can go beyond initial total if needed) - total_thoughts: Current estimate of thoughts needed (can be adjusted up/down) - is_revision: A boolean indicating if this thought revises previous thinking - revises_thought: If is_revision is true, which thought number is being reconsidered - branch_from_thought: If branching, which thought number is the branching point - branch_id: Identifier for the current branch (if any) - needs_more_thoughts: If reaching end but realizing more thoughts needed You should: 1. Start with an initial estimate of needed thoughts, but be ready to adjust 2. Feel free to question or revise previous thoughts 3. Don't hesitate to add more thoughts if needed, even at the "end" 4. Express uncertainty when present 5. Mark thoughts that revise previous thinking or branch into new paths 6. Ignore information that is irrelevant to the current step 7. Generate a solution hypothesis when appropriate 8. Verify the hypothesis based on the Chain of Thought steps 9. Repeat the process until satisfied with the solution 10. Provide a single, ideally correct answer as the final output 11. Only set next_thought_needed to false when truly done and a satisfactory answer is reached
