MCP RAG Development Status - TerrenceMcGuinness-NOAA/global-workflow GitHub Wiki

TerrenceMcGuinness-NOAA: We have serveral MCP servies running for global-workflow: enahced-rag, rag, simle, and wsl. Let's go through all the tools for each and check which ones are operable and not templated. Check the code for each and see what steps need to be taken. It appears we still not have the database connection configured and working to finish some of the tools development. Let's create a table for each of these MCP servers each with paragraph for each table with a breif discription and how the relate to others along with the list of each tool for every table with a column for wihich ones are trurly operable and which onees needs furrther development or implementation.

GitHub Copilot: I'll help you analyze the MCP services for global-workflow. Let me first search for the MCP server implementations and their tools to understand the current state. Let me search more specifically for MCP server implementations and check the WSL server as well: Now let me check for WSL-specific files: Let me look at the main MCP server files to understand the current structure: Now let me check the RAG-enhanced server: Let me check the enhanced RAG server: Let me check the simple RAG server: Now let me check if there's a WSL-specific server or if it's in Python: Now let me examine the tools defined in each server. Let me get the complete tool lists: Let me read the complete tool definitions for each server to create the comparison tables: Now let me get the complete tool definitions for the RAG server: Now let me get the tool definitions for the Enhanced RAG server: Let me get the simple RAG server tools: Now let me check the Python server tools: Now let me check if there are any database initialization or configuration files to understand the current state: Perfect! Now I have enough information to create comprehensive comparison tables for each MCP server. Let me create a comprehensive analysis:

Based on my analysis of the MCP servers, here are the detailed comparison tables for each of the four MCP services for global-workflow:

1. Simple MCP Server (mcp-server.js)

Description: This is the basic Node.js MCP server that provides core global-workflow functionality without RAG enhancements. It serves as the foundation for the other servers and offers straightforward workflow information access. This server focuses on basic repository navigation and documentation without advanced search capabilities.

Tool Name Description Status Implementation Notes
get_workflow_structure Get structure/overview of global workflow system Operational Fully implemented with hardcoded responses
list_job_scripts List all available job scripts in workflow Operational Working directory traversal implementation
get_system_configs Get HPC system configuration information Operational Hardcoded system info, functional
explain_component Explain specific workflow components Operational Basic component explanations available

2. RAG-Enhanced MCP Server (mcp-server-rag.js)

Description: This server extends the basic server with Retrieval-Augmented Generation capabilities using ChromaDB and local embeddings. It includes all tools from the simple server plus advanced RAG features. The server has fallback mechanisms when vector database connections fail, ensuring basic functionality remains available.

Tool Name Description Status Implementation Notes
get_workflow_structure Basic workflow structure info Operational Inherited from simple server
list_job_scripts List workflow job scripts Operational Inherited from simple server
get_system_configs HPC system configurations Operational Inherited from simple server
explain_component Basic component explanations Operational Inherited from simple server
search_documentation Semantic search with RAG ⚠️ Partially Operational Works with local embeddings when ChromaDB fails
explain_with_context RAG-enhanced explanations ⚠️ Partially Operational Requires vector database for full functionality
find_similar_code Vector similarity code search ⚠️ Partially Operational Has local fallback but limited without DB
get_operational_guidance HPC operational procedures ⚠️ Partially Operational Template responses when RAG unavailable
analyze_dependencies Workflow dependency analysis ⚠️ Partially Operational Basic analysis without graph database

3. Enhanced RAG MCP Server (mcp-server-enhanced-rag.js)

Description: This advanced server integrates Hugging Face models and APIs with local RAG capabilities. It's designed to leverage external ML models for documentation enhancement, code analysis, and automated content generation. This server represents the most sophisticated approach but requires external API access and configuration.

Tool Name Description Status Implementation Notes
search_documentation Enhanced semantic search with HF integration ⚠️ Needs Development Requires HF API configuration
enhance_documentation_with_hf HF papers/datasets integration Template Only Requires HuggingFace API setup
find_similar_implementations HF code model integration Template Only Needs HF code model configuration
generate_documentation HF text generation for docs Template Only Requires HF text generation API
get_workflow_structure Basic workflow info Operational Basic functionality works
list_job_scripts Job script listing Operational Basic functionality works
explain_workflow_component Component explanations Operational Basic functionality works
analyze_workflow_dependencies Dependency analysis ⚠️ Partially Operational Limited without full HF integration

4. Simple RAG Server (simple-rag-server.js)

Description: This is a testing/demonstration server that uses basic keyword matching instead of vector embeddings. It's designed for environments where machine learning models aren't available but some RAG-like functionality is needed. It loads pre-processed knowledge bases and provides search capabilities using simple text matching algorithms.

Tool Name Description Status Implementation Notes
search_documentation Keyword-based document search Operational Uses simple keyword matching, works well
explain_component Component explanations with examples Operational Functional with knowledge base loaded
list_workflow_jobs List workflow jobs with filtering Operational Good filtering and categorization
get_knowledge_stats Knowledge base statistics Operational Shows loaded chunks and documents
get_documentation_references External documentation links Operational Provides structured reference links

5. Python MCP Server (mcp-server.py)

Description: This is a Python-based implementation that focuses on basic workflow information without RAG capabilities. It's designed for environments where Python is preferred over Node.js and provides a clean, simple interface to workflow information. This server could serve as the foundation for Python-based RAG implementations.

Tool Name Description Status Implementation Notes
get_workflow_info General workflow information Operational Comprehensive workflow documentation
list_job_scripts List available job scripts Operational File system traversal working
get_config_info System configuration info Operational Basic system information available

Database and Infrastructure Status

Current State Analysis:

  • ChromaDB: Local database exists with 978 chunks processed
  • Embeddings: Pre-computed embeddings available (all-MiniLM-L6-v2, 384 dimensions)
  • Knowledge Base: JSON files with chunks and documents are present
  • ⚠️ Database Connection: ChromaDB server may not be running (connection issues noted in logs)
  • HuggingFace Integration: Configuration files missing, API access not configured
  • ⚠️ Vector Search: Working in fallback mode with local embeddings

Required Steps for Full Functionality

Immediate Actions Needed:

  1. Start ChromaDB Server:

    cd /path/to/mcp_server_node/knowledge-base
    chroma run --host localhost --port 8000 --path ./chroma_db
    
  2. Configure HuggingFace Integration:

    • Create hf_integration/config/huggingface.json with API credentials
    • Set up HF API token in environment variables
  3. Test Database Connections:

    • Verify ChromaDB connectivity
    • Test embedding model loading
    • Validate knowledge base integrity

Development Priorities:

  1. High Priority: Fix ChromaDB connection for RAG server
  2. Medium Priority: Complete HuggingFace integration implementation
  3. Low Priority: Add WSL-specific server if needed for Windows development

The Simple RAG Server is currently the most reliable for demonstration purposes, while the RAG-Enhanced Server offers the best functionality when properly configured.
