What is the Deep Thinker MCP Server?

Advanced cognitive thinking MCP with DAG-based thought graph, 10 reasoning strategies, node aliases, session persistence, structured responses, auto strategy

The short version

  • DAG-Based Thought Graph — — Thoughts form a directed acyclic graph with branching, merging, and cross-edges (not just a linear chain)
  • 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

Recorded tools

  • think — Add a thought to the cognitive graph using a reasoning strategy.
  • evaluate — Evaluate the thinking process with confidence scoring, critique, and graph health analysis.
  • metacog — Metacognitive operations — monitor and control the thinking process.
  • graph — The graph tool exposed by this server.
  • prune — The prune tool exposed by this server.
  • reset — Reset the thought graph and start a fresh session, save, or resume a saved session.
  • conclude — Analyze the entire thought graph and produce a comprehensive summary-conclusion with action items and graph health report.
  • help — The help tool exposed by this server.
  • visualize_thought_graph — Generate visual representation of the thought graph as SVG or ASCII.
  • simulate_devils_advocate — Generate counterarguments and opposing viewpoints for a given thought.
  • cross_disciplinary_synthesis — Combine insights from multiple domains to generate novel perspectives.
  • temporal_projection — The temporal_projection tool exposed by this server.
  • ethical_framework_evaluation — Evaluate a thought or decision through multiple ethical frameworks.
