}Tools
1A 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
Overview
What is Sequential Thinking MCP Server?
A powerful MCP server implementing the sequential thinking protocol that provides a structured approach to problem-solving. It helps break down complex problems into manageable steps while maintaining flexibility for revisions and alternative reasoning paths.
How to use Sequential Thinking MCP Server?
Install and run the server via npx -y @zengwenliang/mcp-server-sequential-thinking or by building a Docker image from the source repository. Then add it to your MCP client’s configuration (e.g., Claude Desktop or Cursor IDE) using the provided JSON settings. The server exposes the sequential_thinking tool for step-by-step analysis.
Key features of Sequential Thinking MCP Server
- Structured Analysis – break down complex problems into manageable steps.
- Iterative Refinement – revise and refine thoughts as understanding deepens.
- Alternative Pathways – branch into alternative paths of reasoning.
- Dynamic Adjustment – adjust the total number of thoughts as needed.
- Solution Validation – generate and verify solution hypotheses.
Use cases of Sequential Thinking MCP Server
- Complex problems requiring step-by-step breakdown.
- Planning and design projects needing iterative refinement.
- Analysis workflows that may require course correction.
- Situations where the full scope isn’t initially clear.
- Tasks that need to maintain context over multiple steps.
FAQ from Sequential Thinking MCP Server
What is the main tool provided by Sequential Thinking MCP Server?
The server exposes the sequential_thinking tool, which facilitates a detailed, step-by-step thinking process for problem-solving and analysis.
How can I integrate Sequential Thinking MCP Server with Claude Desktop?
Use the NPX configuration: set command to npx and args to ["-y", "@zengwenliang/mcp-server-sequential-thinking"], or use the Docker configuration with docker run --rm -i zengwenliang0416/mcp-server-sequential-thinking.
How can I integrate Sequential Thinking MCP Server with Cursor IDE?
Multiple methods are described: NPX (recommended), local build, Docker, or environment variables. The NPX method uses the same command as Claude Desktop; the local build method requires an absolute path to dist/index.js.
What input parameters does the sequential_thinking tool accept?
Required parameters: thought (string), nextThoughtNeeded (boolean), thoughtNumber (integer), totalThoughts (integer). Optional parameters: isRevision, revisesThought, branchFromThought, branchId, needsMoreThoughts.
What are the dependencies for running the server?
The server is written in TypeScript and runs on Node.js. It can be installed via npm or built from source, or used as a Docker image.
