Quick Start

Prerequisites

• Neo4j: Running locally or remote instance (for structured knowledge graphs)

• Qdrant: Vector database for semantic search and embeddings (for hybrid reasoning)

• Python 3.10+: For running the MCP server

• uv: The Python package manager for MCP servers

• Claude Desktop: For using with Claude AI

• MCP-Desktop-Commander: Invaluable for CLI and filesystem operations

• For the Lotka-Volterra Ecosystem and generally enhanced abilities-

• wolframalpha-llm-mcp: really nice!

• mcp-server-qdrant-enhanced: My qdrant-enhanced mcp server

• Optional for more utility

• arxiv-mcp-server

This incarnation is still being developed

• For Code Analysis Incarnation: AST/ASG: Currently needs development and an incarnation re-write

• Get a free API key from WolframAlpha:

To get a free API key (AppID) for Wolfram|Alpha, you need to sign up for a Wolfram ID and then register an application on the Wolfram|Alpha Developer Portal.

Create a Wolfram ID: If you don't already have one, create a Wolfram ID at https://account.wolfram.com/login/create

Navigate to the Developer Portal: Once you have a Wolfram ID, sign in to the Wolfram|Alpha Developer Portal https://developer.wolframalpha.com/portal/myapps

Sign up for your first AppID: Click on the "Sign up to get your first AppID" button.

Fill out the AppID creation dialog: Provide a name and a simple description for your application.

Receive your AppID: After filling out the necessary information, you will be presented with your API key, also referred to as an AppID.

The Wolfram|Alpha API is free for non-commercial usage, and you get up to 2,000 requests per month.

Each application requires its own unique AppID.

The MCP server runs the Python code, bridging the gap between the Neo4j graph and the AI assistant ( e.g. Claude)

Installation

1. Clone the repository

2. Set up Python and the virtual environment

Make sure you have pyenv and uv installed.

3. Install dependencies

4. Start Neo4j and Qdrant

• Neo4j: Start your Neo4j server (locally or remote). Default connection: bolt://localhost:7687

Neo4j connection parameters:

• URL: bolt://localhost:7687 (default)

• Username: neo4j (default)

• Password: Your Neo4j database password

• Database: neo4j (default)

  Set credentials via environment variables if needed:

  • NEO4J_URL

  • NEO4J_USERNAME

  • NEO4J_PASSWORD

  • NEO4J_DATABASE

• Qdrant: For persistent Qdrant storage, use this Docker command (recommended):

  docker run -p 6333:6333 -p 6334:6334 \ -v "$(pwd)/qdrant_storage:/qdrant/storage:z" \ qdrant/qdrant

  This will store Qdrant data in a qdrant_storage folder in your project directory.

5. (Optional) VS Code users

• Open the Command Palette (Ctrl+Shift+P), select Python: Select Interpreter, and choose .venv/bin/python.

1. It should auto-install when using the config- not sure anymore haven't tried that and some dependencies are rather large.

Potential Quickstart- lol sorry

Recommended: Claude Desktop Integration:

Configure Claude Desktop by adding the following to your claude-app-config.json:

Important: The password in this configuration must match your Neo4j database password.

Otherwise- Install dependencies: Quick Troubleshooting:

• If you see errors about missing packages, double-check that your .venv is activated and you are using the correct Python version.

• If you need to reset your environment, you can remove .venv and repeat the steps above.

• Can't conect to DB? Install neo4j Desktop and QDRANT. Make sure they are running. NEO4J requires a password set.

You are now ready to use NeoCoder with full Neo4j and Qdrant hybrid Lotka-Volterra Ecosystem reasoning!

Suggested system prompt

Multiple Incarnations

NeoCoder supports multiple "incarnations" - different operational modes that adapt the system for specialized use cases while preserving the core Neo4j graph structure. In a graph-native stack, the same Neo4j core can manifest as very different "brains" simply by swapping templates and execution policies.

Key Architectural Principles

The NeoCoder split is highly adaptable because:

• Neo4j stores facts as first-class graph objects

• Workflows live in template nodes

• Execution engines simply walk the graph

Because these three tiers are orthogonal, you can freeze one layer while morphing the others—turning a code-debugger today into a lab notebook or a learning management system tomorrow. This design echoes Neo4j's own "from graph to knowledge-graph" maturation path where schema, semantics, and operations are deliberately decoupled.

Common Graph Schema Motifs

All incarnations share these core elements:

Available Incarnations:

• base_incarnation (default) - Original NeoCoder, Tool, Templates and Incarnations Workflow management

• research_incarnation - Scientific research platform for hypothesis tracking and experiments

  • Register hypotheses, design experiments, capture runs, and publish outcomes

  • Neo4j underpins provenance pilots for lab workflows with lineage queries

• decision_incarnation - Decision analysis and evidence tracking system

  • Create decision alternatives with expected-value metrics

  • Bayesian updater agents re-compute metric posteriors when new evidence arrives

  • Transparent, explainable reasoning pipelines

• data_analysis_incarnation - Complex system modeling and simulation

  • Model components with state vectors and physical couplings

  • Simulate failure propagation using path queries

  • Optional quantum-inspired scheduler for parameter testing

• knowledge_graph_incarnation - Advanced Hybrid Reasoning System

  • Hybrid Knowledge Queries: Combine Neo4j structured data with Qdrant semantic search

  • Dynamic Knowledge Extraction: Process documents into both graph and vector representations

  • F-Contraction Synthesis: Intelligently merge similar concepts while preserving source attribution

  • Citation-Based Reasoning: Full source tracking across multiple databases

  • Research Analysis Engine: Specialized workflows for academic paper processing

  • Smart Query Routing: AI automatically determines optimal data source strategy

  • Cross-Database Navigation: Seamless linking between structured facts and semantic content

  • Conflict Detection: Identify and flag inconsistencies between sources

  • Real-Time Knowledge Synthesis: Dynamic graph construction from conversations and documents

• code_analysis_incarnation - Code analysis using Abstract Syntax Trees

  • Parse and analyze code structure using AST and ASG tools

  • Track code complexity and quality metrics

  • Compare different versions of code

  • Generate documentation from code analysis

  • Identify code smells and potential issues

Each incarnation provides its own set of specialized tools that are automatically registered when the server starts. These tools are available for use in Claude or other AI assistants that connect to the MCP server.

Implementation Roadmap

NeoCoder features an implementation roadmap that includes:

1. LevelEnv ↔ Neo4j Adapter: Maps events to graph structures and handles batch operations

2. Amplitude Register (Quantum Layer): Optional quantum-inspired layer for superposition states

3. Scheduler: Prioritizes tasks based on entropy and impact scores

4. Re-using TAG assets: Leverages existing abstractions for vertical information hiding

Starting with a Specific Incarnation

Incarnations can also be switched at runtime using the switch_incarnation() tool:

Dynamic Incarnation Loading

NeoCoder features a fully dynamic incarnation loading system, which automatically discovers and loads incarnations from the incarnations directory. This means:

1. No hardcoded imports: New incarnations can be added without modifying server.py

2. Auto-discovery: Just add a new file with the format *_incarnation.py to the incarnations directory

3. All tools available: Tools from all incarnations are registered and available, even if that incarnation isn't active

4. Easy extension: Create new incarnations with the provided template

Creating a New Incarnation

To create a new incarnation:

1. Create a new file in the src/mcp_neocoder/incarnations/ directory with the naming pattern your_incarnation_name_incarnation.py

2. Use this template structure:

3. Add your incarnation type to the IncarnationType enum in polymorphic_adapter.py

4. Restart the server, and your new incarnation will be automatically discovered

See incarnations.md for detailed documentation on using and creating incarnations.

Available Templates

NeoCoder comes with these standard templates:

Hybrid Query Architecture

The KNOWLEDGE_QUERY template implements a sophisticated 3-step reasoning process:

Step 1: Smart Query Router

• Intent Classification: AI analyzes queries to determine optimal data source strategy

• Query Types:

  • Graph-centric: "Who works with whom?", "Show dependency chain"

  • Vector-centric: "What are opinions on X?", "Find discussions about Y"

  • Hybrid: "What did [person from graph] say about [semantic topic]?"

• Execution Planning: Designs multi-step plans for complex hybrid queries

Step 2: Parallelized Data Retrieval

• Neo4j Queries: Execute Cypher queries for structured facts and relationships

• Qdrant Searches: Perform semantic searches across document collections

• Sequential Optimization: For hybrid queries, use graph results to refine vector searches

Step 3: Cross-Database Synthesizer

• Intelligent Synthesis: Combine structured facts with semantic context

• Source Prioritization: Neo4j facts as authoritative, Qdrant for nuance and opinion

• Mandatory Citations: Every claim attributed to specific sources

• Conflict Detection: Identify and flag inconsistencies between data sources

Dynamic Knowledge Extraction (F-Contraction)

The KNOWLEDGE_EXTRACT template implements dynamic knowledge synthesis inspired by graph contraction principles:

Core F-Contraction Concepts:

• Vertices as Concepts: Each distinct concept becomes a graph entity

• Edges as Relationships: Track co-occurrence and explicit connections

• Source Preservation: Maintain pointers to all original sources after merging

Knowledge Processing Pipeline:

1. Document Ingestion: Parse PDFs, text, code, conversations

2. Dual Storage: Chunk text for Qdrant, extract entities for Neo4j

3. Entity Extraction: Identify Papers, Authors, Concepts, Methods, etc.

4. Relationship Discovery: Find citations, dependencies, semantic connections

5. F-Contraction Merging: Intelligently consolidate similar entities

6. Cross-Reference Mapping: Link graph entities to vector document chunks

7. Quality Validation: Ensure consistency and completeness

Research Analysis Engine

Specialized capabilities for academic and technical document processing:

• Citation Graph Construction: Build networks of paper relationships

• Multi-Hop Reasoning: "Trace evolution of transformer architecture through citation links"

• Conflict Analysis: "How does definition of X in Paper A differ from Paper B?"

• Temporal Synthesis: Track concept evolution across time and sources

• Cross-Domain Integration: Combine findings from multiple research domains

Benefits of Hybrid Reasoning

1. Unprecedented Synthesis: Answers impossible with single data sources

2. Source Transparency: Complete audit trail from raw data to conclusions

3. Conflict Awareness: Explicit handling of contradictory information

4. Semantic Enrichment: Structured facts enhanced with contextual understanding

5. Dynamic Learning: Knowledge base improves through F-Contraction merging

Customizing Templates

Templates are stored in the templates directory as .cypher files. You can edit existing templates or create new ones.

To add a new template:

1. Create a new file in the templates directory (e.g., custom_template.cypher)

2. Follow the format of existing templates

3. Initialize the database to load the template into Neo4j

The 'Cypher Snippet Toolkit' tools operate on the graph structure defined below

Below is a consolidated, Neo4j 5-series–ready toolkit you can paste straight into Neo4j Browser, Cypher shell, or any driver. It creates a mini-documentation graph where every (:CypherSnippet) node stores a piece of Cypher syntax, an example, and metadata; text and (optionally) vector indexes make the snippets instantly searchable from plain keywords or embeddings.

1 · Schema & safety constraints

2 · Indexes that power search

If your build is ≤5.14, call

3 · Template to store a snippet

Parameter maps keep code reusable and prevent query-plan recompilation.

4 · How to search

4-A Exact / prefix match via TEXT index

4-B Ranked full-text search

4-C Embedding similarity (vector search)

5 · Updating or deleting snippets

Both operations automatically maintain index consistency – no extra work required.

6 · Bulk export / import (APOC)

This writes share-ready Cypher that can be replayed with cypher-shell < cypher_snippets.cypher.

Quick-start recap

1. Run Section 1 & 2 once per database to set up constraints and indexes.

2. Use Section 3 (param-driven) to add new documentation entries.

3. Query with Section 4, and optionally add vector search if you store embeddings.

4. Backup or publish with Section 6.

With these building blocks you now have a living, searchable "Cypher cheat-sheet inside Cypher" that always stays local, versionable, and extensible. Enjoy friction-free recall as your query repertoire grows!
