sequential-thinking
0
Structures complex problem solving through stepwise reasoning, revisions, alternative approaches, and scope adjustment.
Use when complex problems require systematic step-by-step reasoning with ability to revise thoughts, branch into alternative approaches, or dynamically adjust scope. Ideal for multi-stage analysis, design planning, problem decomposition, or tasks with initially unclear scope.
Understand the trade-offs.

# Sequential Thinking
Enables structured problem-solving through iterative reasoning with revision and branching capabilities.
## Core Capabilities
- **Iterative reasoning**: Break complex problems into sequential thought steps
- **Dynamic scope**: Adjust total thought count as understanding evolves
- **Revision tracking**: Reconsider and modify previous conclusions
- **Branch exploration**: Explore alternative reasoning paths from any point
- **Maintained context**: Keep track of reasoning chain throughout analysis
## When to Use
Use `mcp__reasoning__sequentialthinking` when:
- Problem requires multiple interconnected reasoning steps
- Initial scope or approach is uncertain
- Need to filter through complexity to find core issues
- May need to backtrack or revise earlier conclusions
- Want to explore alternative solution paths
**Don't use for**: Simple queries, direct facts, or single-step tasks.
## Basic Usage
The MCP tool `mcp__reasoning__sequentialthinking` accepts these parameters:
### Required Parameters
- `thought` (string): Current reasoning step
- `nextThoughtNeeded` (boolean): Whether more reasoning is needed
- `thoughtNumber` (integer): Current step number (starts at 1)
- `totalThoughts` (integer): Estimated total steps needed
### Optional Parameters
- `isRevision` (boolean): Indicates this revises previous thinking
- `revisesThought` (integer): Which thought number is being reconsidered
- `branchFromThought` (integer): Thought number to branch from
- `branchId` (string): Identifier for this reasoning branch
## Workflow Pattern
```
1. Start with initial thought (thoughtNumber: 1)
2. For each step:
- Express current reasoning in `thought`
- Estimate remaining work via `totalThoughts` (adjust dynamically)
- Set `nextThoughtNeeded: true` to continue
3. When reaching conclusion, set `nextThoughtNeeded: false`
```
## Simple Example
```typescript
// First thought
{
thought: "Problem involves optimizing database queries. Need to identify bottlenecks first.",
thoughtNumber: 1,
totalThoughts: 5,
nextThoughtNeeded: true
}
// Second thought
{
thought: "Analyzing query patterns reveals N+1 problem in user fetches.",
thoughtNumber: 2,
totalThoughts: 6, // Adjusted scope
nextThoughtNeeded: true
}
// ... continue until done
```
## Advanced Features
For revision patterns, branching strategies, and complex workflows, see:
- [Advanced Usage](references/advanced.md) - Revision and branching patterns
- [Examples](references/examples.md) - Real-world use cases
## Tips
- Start with rough estimate for `totalThoughts`, refine as you progress
- Use revision when assumptions prove incorrect
- Branch when multiple approaches seem viable
- Express uncertainty explicitly in thoughts
- Adjust scope freely - accuracy matters less than progress visibility
