mcp-sequentialthinking-tools

An adaptation of the MCP Sequential Thinking Server designed to guide tool usage in problem-solving. This server helps break down complex problems into manageable steps and provides recommendations for which MCP tools would be most effective at each stage.

A Model Context Protocol (MCP) server that combines sequential thinking with intelligent tool suggestions. For each step in the problem-solving process, it provides confidence-scored recommendations for which tools to use, along with rationale for why each tool would be appropriate.

Features

🤔 Dynamic and reflective problem-solving through sequential thoughts
🔄 Flexible thinking process that adapts and evolves
🌳 Support for branching and revision of thoughts
🛠️ Intelligent tool recommendations for each step
📊 Confidence scoring for tool suggestions
🔍 Detailed rationale for tool recommendations
📝 Step tracking with expected outcomes
🔄 Progress monitoring with previous and remaining steps
🎯 Alternative tool suggestions for each step

How It Works

This server analyses each step of your thought process and recommends appropriate MCP tools to help accomplish the task. Each recommendation includes:

A confidence score (0-1) indicating how well the tool matches the current need
A clear rationale explaining why the tool would be helpful
A priority level to suggest tool execution order
Alternative tools that could also be used

The server works with any MCP tools available in your environment. It provides recommendations based on the current step's requirements, but the actual tool execution is handled by the consumer (like Claude).

Example Usage

Here's an example of how the server guides tool usage:

{
	"thought": "Initial research step to understand what universal reactivity means in Svelte 5",
	"current_step": {
		"step_description": "Gather initial information about Svelte 5's universal reactivity",
		"expected_outcome": "Clear understanding of universal reactivity concept",
		"recommended_tools": [
			{
				"tool_name": "search_docs",
				"confidence": 0.9,
				"rationale": "Search Svelte documentation for official information",
				"priority": 1
			},
			{
				"tool_name": "tavily_search",
				"confidence": 0.8,
				"rationale": "Get additional context from reliable sources",
				"priority": 2
			}
		],
		"next_step_conditions": [
			"Verify information accuracy",
			"Look for implementation details"
		]
	},
	"thought_number": 1,
	"total_thoughts": 5,
	"next_thought_needed": true
}

The server tracks your progress and supports:

Creating branches to explore different approaches
Revising previous thoughts with new information
Maintaining context across multiple steps
Suggesting next steps based on current findings

Configuration

This server requires configuration through your MCP client. Here are examples for different environments:

Cline Configuration

Add this to your Cline MCP settings:

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

Claude Desktop with WSL Configuration

For WSL environments, add this to your Claude Desktop configuration:

{
	"mcpServers": {
		"mcp-sequentialthinking-tools": {
			"command": "wsl.exe",
			"args": [
				"bash",
				"-c",
				"source ~/.nvm/nvm.sh && /home/username/.nvm/versions/node/v20.12.1/bin/npx mcp-sequentialthinking-tools"
			]
		}
	}
}

API

The server implements a single MCP tool with configurable parameters:

sequentialthinking_tools

A tool for dynamic and reflective problem-solving through thoughts, with intelligent tool recommendations.

Parameters:

thought (string, required): Your current thinking step

thought_number (integer, required): Current thought number
total_thoughts (integer, required): Estimated total thoughts needed
is_revision (boolean, optional): Whether this revises previous thinking
revises_thought (integer, optional): Which thought is being reconsidered
branch_from_thought (integer, optional): Branching point thought number
branch_id (string, optional): Branch identifier
needs_more_thoughts (boolean, optional): If more thoughts are needed
current_step (object, optional): Current step recommendation with:
- step_description: What needs to be done
- recommended_tools: Array of tool recommendations with confidence scores
- expected_outcome: What to expect from this step
- next_step_conditions: Conditions for next step
previous_steps (array, optional): Steps already recommended
remaining_steps (array, optional): High-level descriptions of upcoming steps
