Each thought is validated using Pydantic models, categorized into thinking stages, and stored with relevant metadata in a thread-safe storage system. The server automatically handles data persistence, backup creation, and provides tools for analyzing relationships between thoughts. 137 | 138 | ## Usage Guide 139 | 140 | The Sequential Thinking server exposes three main tools: 141 | 142 | ### 1. `process_thought` 143 | 144 | Records and analyzes a new thought in your sequential thinking process. 145 | 146 | **Parameters:** 147 | 148 | - `thought` (string): The content of your thought 149 | - `thought_number` (integer): Position in your sequence (e.g., 1 for first thought) 150 | - `total_thoughts` (integer): Expected total thoughts in the sequence 151 | - `next_thought_needed` (boolean): Whether more thoughts are needed after this one 152 | - `stage` (string): The thinking stage - must be one of: 153 | - "Problem Definition" 154 | - "Research" 155 | - "Analysis" 156 | - "Synthesis" 157 | - "Conclusion" 158 | - `tags` (list of strings, optional): Keywords or categories for your thought 159 | - `axioms_used` (list of strings, optional): Principles or axioms applied in your thought 160 | - `assumptions_challenged` (list of strings, optional): Assumptions your thought questions or challenges 161 | 162 | **Example:** 163 | 164 | ```python 165 | # First thought in a 5-thought sequence 166 | process_thought( 167 | thought="The problem of climate change requires analysis of multiple factors including emissions, policy, and technology adoption.", 168 | thought_number=1, 169 | total_thoughts=5, 170 | next_thought_needed=True, 171 | stage="Problem Definition", 172 | tags=["climate", "global policy", "systems thinking"], 173 | axioms_used=["Complex problems require multifaceted solutions"], 174 | assumptions_challenged=["Technology alone can solve climate change"] 175 | ) 176 | ``` 177 | 178 | ### 2. `generate_summary` 179 | 180 | Generates a summary of your entire thinking process. 181 | 182 | **Example output:** 183 | 184 | ```json 185 | { 186 | "summary": { 187 | "totalThoughts": 5, 188 | "stages": { 189 | "Problem Definition": 1, 190 | "Research": 1, 191 | "Analysis": 1, 192 | "Synthesis": 1, 193 | "Conclusion": 1 194 | }, 195 | "timeline": [ 196 | {"number": 1, "stage": "Problem Definition"}, 197 | {"number": 2, "stage": "Research"}, 198 | {"number": 3, "stage": "Analysis"}, 199 | {"number": 4, "stage": "Synthesis"}, 200 | {"number": 5, "stage": "Conclusion"} 201 | ] 202 | } 203 | } 204 | ``` 205 | 206 | ### 3. `clear_history` 207 | 208 | Resets the thinking process by clearing all recorded thoughts. 209 | 210 | ## Practical Applications 211 | 212 | - **Decision Making**: Work through important decisions methodically 213 | - **Problem Solving**: Break complex problems into manageable components 214 | - **Research Planning**: Structure your research approach with clear stages 215 | - **Writing Organization**: Develop ideas progressively before writing 216 | - **Project Analysis**: Evaluate projects through defined analytical stages 217 | 218 | 219 | ## Getting Started 220 | 221 | With the proper MCP setup, simply use the `process_thought` tool to begin working through your thoughts in sequence. As you progress, you can get an overview with `generate_summary` and reset when needed with `clear_history`. 222 | 223 | 224 | 225 | # Customizing the Sequential Thinking Server 226 | 227 | For detailed examples of how to customize and extend the Sequential Thinking server, see [example.md](example.md).

Modifying Thinking Stages 20 | 21 | You can customize the thinking stages by modifying the `ThoughtStage` enum in `models.py`: 22 | 23 | ```python 24 | class ThoughtStage(Enum): 25 | """Custom thinking stages for your specific workflow.""" 26 | OBSERVE = "Observe" 27 | HYPOTHESIZE = "Hypothesize" 28 | EXPERIMENT = "Experiment" 29 | ANALYZE = "Analyze" 30 | CONCLUDE = "Conclude" 31 | ``` 32 | 33 | ## 2. Enhancing Thought Data Structure 34 | 35 | Extend the `ThoughtData` class to include additional fields: 36 | 37 | ```python 38 | from pydantic import Field, field_validator 39 | class EnhancedThoughtData(ThoughtData): 40 | """Enhanced thought data with additional fields.""" 41 | confidence_level: float = 0.0 42 | supporting_evidence: List[str] = Field(default_factory=list) 43 | counter_arguments: List[str] = Field(default_factory=list) 44 | 45 | @field_validator('confidence_level') 46 | def validate_confidence_level(cls, value): 47 | """Validate confidence level.""" 48 | if not 0.0 <= value <= 1.0: 49 | raise ValueError("Confidence level must be between 0.0 and 1.0") 50 | return value 51 | ``` 52 | 53 | ## 3. Adding Persistence with a Database 54 | 55 | Implement a database-backed storage solution: 56 | 57 | ```python 58 | from sqlalchemy import create_engine, Column, Integer, String, Float, Boolean, ForeignKey 59 | from sqlalchemy.ext.declarative import declarative_base 60 | from sqlalchemy.orm import sessionmaker, relationship 61 | 62 | Base = declarative_base() 63 | 64 | class ThoughtModel(Base): 65 | """SQLAlchemy model for thought data.""" 66 | __tablename__ = "thoughts" 67 | 68 | id = Column(Integer, primary_key=True) 69 | thought = Column(String, nullable=False) 70 | thought_number = Column(Integer, nullable=False) 71 | total_thoughts = Column(Integer, nullable=False) 72 | next_thought_needed = Column(Boolean, nullable=False) 73 | stage = Column(String, nullable=False) 74 | timestamp = Column(String, nullable=False) 75 | 76 | tags = relationship("TagModel", back_populates="thought") 77 | axioms = relationship("AxiomModel", back_populates="thought") 78 | assumptions = relationship("AssumptionModel", back_populates="thought") 79 | 80 | class DatabaseStorage: 81 | """Database-backed storage for thought data.""" 82 | 83 | def __init__(self, db_url: str = "sqlite:///thoughts.db"): 84 | """Initialize database connection.""" 85 | self.engine = create_engine(db_url) 86 | Base.metadata.create_all(self.engine) 87 | self.Session = sessionmaker(bind=self.engine) 88 | 89 | def add_thought(self, thought: ThoughtData) -> None: 90 | """Add a thought to the database.""" 91 | with self.Session() as session: 92 | # Convert ThoughtData to ThoughtModel 93 | thought_model = ThoughtModel( 94 | thought=thought.thought, 95 | thought_number=thought.thought_number, 96 | total_thoughts=thought.total_thoughts, 97 | next_thought_needed=thought.next_thought_needed, 98 | stage=thought.stage.value, 99 | timestamp=thought.timestamp 100 | ) 101 | 102 | session.add(thought_model) 103 | session.commit() 104 | ``` 105 | 106 | ## 4. Implementing Enhanced Analysis 107 | 108 | Add more sophisticated analysis capabilities: 109 | 110 | ```python 111 | from sklearn.feature_extraction.text import TfidfVectorizer 112 | from sklearn.metrics.pairwise import cosine_similarity 113 | import numpy as np 114 | 115 | class AdvancedAnalyzer: 116 | """Advanced thought analysis using NLP techniques.""" 117 | 118 | def __init__(self): 119 | """Initialize the analyzer.""" 120 | self.vectorizer = TfidfVectorizer() 121 | self.thought_vectors = None 122 | self.thoughts = [] 123 | 124 | def add_thought(self, thought: ThoughtData) -> None: 125 | """Add a thought to the analyzer.""" 126 | self.thoughts.append(thought) 127 | # Recompute vectors 128 | self._compute_vectors() 129 | 130 | def _compute_vectors(self) -> None: 131 | """Compute TF-IDF vectors for all thoughts.""" 132 | if not self.thoughts: 133 | return 134 | 135 | thought_texts = [t.thought for t in self.thoughts] 136 | self.thought_vectors = self.vectorizer.fit_transform(thought_texts) 137 | 138 | def find_similar_thoughts(self, thought: ThoughtData, top_n: int = 3) -> List[Tuple[ThoughtData, float]]: 139 | """Find thoughts similar to the given thought using cosine similarity.""" 140 | if thought not in self.thoughts: 141 | self.add_thought(thought) 142 | 143 | thought_idx = self.thoughts.index(thought) 144 | thought_vector = self.thought_vectors[thought_idx] 145 | 146 | # Compute similarities 147 | similarities = cosine_similarity(thought_vector, self.thought_vectors).flatten() 148 | 149 | # Get top N similar thoughts (excluding self) 150 | similar_indices = np.argsort(similarities)[::-1][1:top_n+1] 151 | 152 | return [(self.thoughts[idx], similarities[idx]) for idx in similar_indices] 153 | ``` 154 | 155 | ## 5. Creating Custom Prompts 156 | 157 | Add custom prompts to guide the thinking process: 158 | 159 | ```python 160 | from mcp.server.fastmcp.prompts import base 161 | 162 | @mcp.prompt() 163 | def problem_definition_prompt(problem_statement: str) -> list[base.Message]: 164 | """Create a prompt for the Problem Definition stage.""" 165 | return [ 166 | base.SystemMessage( 167 | "You are a structured thinking assistant helping to define a problem clearly." 168 | ), 169 | base.UserMessage(f"I need to define this problem: {problem_statement}"), 170 | base.UserMessage( 171 | "Please help me create a clear problem definition by addressing:\n" 172 | "1.
