Features

DAG-Based Thought Graph — Thoughts form a directed acyclic graph with branching, merging, and cross-edges (not just a linear chain)
10 Reasoning Strategies — Sequential, Dialectic (thesis→antithesis→synthesis), Parallel, Analogical, Abductive, First Principles (deconstruct to fundamentals), Counterfactual (what-if with ripple effects), Systems Thinking (feedback loops & leverage points), MCTS (Monte Carlo optimization), Auto (intelligent auto-selection based on content and graph state)
Node Aliases — Use "last", "best", "root" instead of cryptic node IDs for any nodeId parameter
Structured Responses — All tool responses return consistent MCPResponse JSON with status, summary, confidence, nextSuggested action
Session Persistence — Auto-saves thought graph to ~/.deep-thinker/sessions/; resume across MCP restarts with reset({ resume: "name" })
Friendly Error Messages — Zod validation errors translated to human-readable hints (e.g., "confidence 0 ile 1 arasında...")
Confidence Scoring — Multi-factor confidence evaluation with support/contradiction analysis, depth penalties, and knowledge integration boosts
Self-Critique — Automatic critique generation with severity levels and confidence adjustments
Metacognitive Engine — Detects stuck states, stagnation, declining confidence; suggests strategy switches and corrective actions
Knowledge Integration — Attach external knowledge to thoughts, detect gaps, validate consistency across sources
Thought Pruning — Dead-end detection, redundancy removal, deep unproductive branch elimination, path optimization

Installation

Global

npm install -g deep-thinker

npx (no install)

npx deep-thinker

MCP Configuration

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "deep-thinker": {
      "command": "npx",
      "args": ["-y", "deep-thinker"]
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "deep-thinker": {
      "command": "deep-thinker"
    }
  }
}

Other MCP Clients

The server communicates over stdio. Point your MCP client to the deep-thinker command or node path/to/dist/index.js.

Response Format

All tool responses follow the MCPResponse structure:

{
  "status": "ok | error | warning",
  "nodeId": "thought_3",
  "summary": "sequential stratejisiyle \"Should we use microservices?...\" eklendi",
  "confidence": 0.75,
  "data": { "...": "tool-specific data" },
  "nextSuggested": {
    "tool": "evaluate",
    "params": { "critique": true },
    "reason": "Düşük confidence — değerlendirme önerilir"
  },
  "warnings": ["Stuck detected: ..."]
}

The nextSuggested field always recommends the next logical step, making it easy to chain tool calls without guessing.

Node Aliases

Instead of looking up cryptic node IDs, use aliases for any nodeId, parentId, or targetId parameter:

Alias	Resolves To
`"last"`	Most recently added node (insertion order)
`"best"`	Node with highest confidence score
`"root"`	First node with no incoming edges

evaluate({ nodeId: "last" })                              → evaluates the latest thought
simulate_devils_advocate({ nodeId: "best", depth: 2 })    → challenges the strongest thought
graph({ action: "path", nodeId: "root", targetId: "best" }) → traces from root to best conclusion

Session Persistence

Thought graphs are automatically saved after every think call. Sessions are stored in ~/.deep-thinker/sessions/.

// Save current session explicitly
reset({ save: true, saveName: "my-analysis" })

// List saved sessions
reset({ listSessions: true })

// Resume a saved session after MCP restart
reset({ resume: "my-analysis" })

Strategy details:

Strategy	Description	Best For
Sequential	Linear chain: each thought derives from the previous	Step-by-step reasoning
Dialectic	Thesis → Antithesis → Synthesis pattern to resolve contradictions	Resolving conflicts
Parallel	Explore multiple independent branches simultaneously	Brainstorming options
Analogical	Map patterns from a known domain to the current problem	Cross-domain insights
Abductive	Generate hypotheses and infer the best explanation	Root cause analysis
First Principles	Deconstruct to fundamental truths, challenge assumptions	Breaking conventions
Counterfactual	"What-if" scenarios with multi-stage ripple effects	Risk/impact analysis
Systems Thinking	Feedback loops, leverage points, emergent properties	Complex systems
MCTS	Monte Carlo Tree Search for optimal decision selection	Optimization problems
Auto	Automatically selects strategy based on content signals and graph context	Hands-off reasoning

How auto strategy works:

The auto strategy analyzes your content for keywords and the current graph state:

Content with "why"/"neden"/"how"/"nasıl" → abductive
Content with "if"/"eğer"/"what if"/"varsayalım" → counterfactual
Content with "vs"/"veya"/"compare"/"karşılaştır" → dialectic
Content with "system"/"sistem"/"loop"/"döngü" → systems_thinking
Content with "fundamental"/"temel"/"assumption"/"varsayım" → first_principles
Low avg confidence + many nodes → parallel (break through impasse)
First thought → sequential
After 4+ sequential thoughts → dialectic (introduce opposing view)
Default → sequential

Usage Examples

Auto Strategy Selection (New!)

think: { content: "Eğer mikroservis kullansaydık ne olurdu?" }
→ Auto-selects strategy: counterfactual (detected "Eğer" = "if" signal)

think: { content: "Why is the server crashing?" }
→ Auto-selects strategy: abductive (detected "why" signal)

think: { content: "Monolith vs microservices?" }
→ Auto-selects strategy: dialectic (detected "vs" comparison signal)

Sequential Reasoning

think: "Should we use microservices?" → type: question, confidence: 0.9
think: "Monolith has deployment bottlenecks" → type: analysis, confidence: 0.7
think: "Team lacks DevOps capacity for microservices" → type: evidence, confidence: 0.8
evaluate: { nodeId: "last", critique: true }
→ { status: "ok", confidence: 0.73, nextSuggested: { tool: "metacog" } }

Dialectic Reasoning

think: {
  strategy: "dialectic",
  dialectic: {
    thesis: "Microservices improve scalability",
    antithesis: "But add operational complexity",
    synthesis: "Use modular monolith as middle ground"
  },
  confidence: 0.75
}

Using Node Aliases

evaluate({ nodeId: "last" })                              → evaluate latest thought
simulate_devils_advocate({ nodeId: "best", depth: 3 })    → challenge strongest thought
graph({ action: "path", nodeId: "root", targetId: "best" }) → trace reasoning path
think({ parentId: "root", content: "Alternative..." })    → branch from root

Session Save & Resume

// Work on a problem...
think({ content: "Analysis...", strategy: "auto" })
think({ content: "Another insight..." })

// Save before closing
reset({ save: true, saveName: "architecture-review" })

// ... MCP restarts ...

// Resume exactly where you left off
reset({ resume: "architecture-review" })
→ { status: "ok", summary: "architecture-review oturumu geri yüklendi — 5 node ile devam ediliyor" }

First Principles Reasoning

think: {
  strategy: "first_principles",
  firstPrinciples: {
    problem: "How to improve battery efficiency?",
    assumptions: ["Batteries must use lithium", "Charging takes hours"],
    depth: 3,
    domain: "physics"
  }
}
→ Creates: Problem → Assumptions Challenged → Fundamental Truths → Reconstructed Solution

Counterfactual (What-If) Analysis

think: {
  strategy: "counterfactual",
  counterfactual: {
    currentState: "Office-based work with 5-day commute",
    variablesToChange: [
      { variable: "work_location", currentValue: "office", hypotheticalValue: "remote", impactWeight: 0.9 },
      { variable: "commute_days", currentValue: 5, hypotheticalValue: 0, impactWeight: 0.8 }
    ],
    timeHorizon: "medium_term",
    rippleDepth: 3
  }
}
→ Creates: Baseline → Variable Changes → Stage 1/2/3 Ripple Effects → Scenarios → Risk Analysis

Systems Thinking

think: {
  strategy: "systems_thinking",
  systemsThinking: {
    systemDescription: "Software development team dynamics",
    components: [
      { name: "FeatureBacklog", type: "stock", description: "Pending work" },
      { name: "DeveloperCapacity", type: "stock", description: "Available developers" },
      { name: "CodeReviews", type: "flow", description: "Review process" },
      { name: "Quality", type: "converter", description: "Quality gates" }
    ],
    focusArea: "feedback_loops"
  }
}
→ Creates: System Overview → Components → Feedback Loops → Leverage Points → Recommendations

MCTS (Monte Carlo Tree Search)

think: {
  strategy: "mcts",
  mcts: {
    problem: "Which architecture pattern to choose?",
    possibleActions: [
      { id: "microservices", description: "Microservices architecture", estimatedReward: 0.7 },
      { id: "monolith", description: "Monolithic architecture", estimatedReward: 0.5 },
      { id: "modular", description: "Modular monolith", estimatedReward: 0.8 }
    ],
    numSimulations: 100,
    pruningThreshold: 0.2
  }
}
→ Creates: Root → Actions → Simulations → Pruning Analysis → Optimal Path

Conclude Analysis

conclude({ detailLevel: "detailed" })
→ {
  status: "ok",
  summary: "12 dusunce, 3 dal, sequential+counterfactual stratejileriyle analiz tamamlandi",
  data: {
    conclusion: { primaryFinding: "...", confidence: 0.85 },
    actionItems: [{ action: "Investigate...", priority: "high" }, ...],
    graphHealth: { totalThoughts: 12, avgConfidence: 0.72, recommendation: "Graf saglikli gorunuyor" }
  },
  nextSuggested: { tool: "reset", params: { save: true }, reason: "Analizi kaydetmeyi unutmayin" }
}

Metacognitive Guidance

metacog: { action: "auto_update" }
→ Stuck detected + suggested action in nextSuggested

metacog: { action: "switch", strategy: "parallel", reason: "Break through impasse" }
→ Strategy switched + next step recommended

Pruning

prune: { action: "analyze" }
→ Dead Ends, Redundant Branches, Total prunable count

prune: { action: "prune" }
→ Nodes pruned + metacog updated + nextSuggested

Getting Help

help()                    → all tools, all categories, all workflows
help({ category: "core" })     → 7 core tools with quick-start examples
help({ category: "advanced" }) → 9 advanced tools
help({ category: "workflow" }) → 3 recommended workflows

Friendly Error Messages

When validation fails, you get human-readable errors instead of raw Zod output:

think({ confidence: 1.5 })
→ {
  status: "error",
  error: "VALIDATION_ERROR",
  message: "\"confidence\" parametresinde hata: ...",
  field: "confidence",
  hint: "confidence 0 ile 1 arasında bir sayı olmalı. Örnek: confidence: 0.7"
}

evaluate({ nodeId: "nonexistent" })
→ {
  status: "error",
  error: "NODE_NOT_FOUND",
  provided: "nonexistent",
  hint: "Geçerli alias'lar: \"last\", \"best\", \"root\" veya graph aracıyla node ID alın"
}
