View on GitHub ↗Sequential Thinking MCP Server
An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process.
Published on npm as @modelcontextprotocol/server-sequential-thinking.
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 stepnextThoughtNeeded(boolean): Whether another thought step is neededthoughtNumber(integer): Current thought numbertotalThoughts(integer): Estimated total thoughts neededisRevision(boolean, optional): Whether this revises previous thinkingrevisesThought(integer, optional): Which thought is being reconsideredbranchFromThought(integer, optional): Branching point thought numberbranchId(string, optional): Branch identifierneedsMoreThoughts(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
In practice, you do not call sequential_thinking directly by hand unless your client exposes raw tool calls. Instead, connect the server to an MCP-aware host and ask the model to think through a problem step by step. The host can then decide to call the tool one or more times while it works.
What it looks like in use
Example prompts that typically benefit from this tool:
Plan a database migration from PostgreSQL 14 to 16, list risks, and revise the plan if downtime exceeds 5 minutes.Debug why this deployment only fails in production and show your reasoning step by step.Compare three architecture options for a file sync engine and branch if one assumption turns out to be wrong.
