RAG Information Retriever

A powerful MCP server that implements Retrieval-Augmented Generation (RAG) to efficiently retrieve and process important information from various sources. This server combines the strengths of retrieval-based and generation-based approaches to provide accurate and contextually relevant information.

Features

Intelligent Information Retrieval
- Semantic search capabilities
- Context-aware information extraction
- Relevance scoring and ranking
- Multi-source data integration
RAG Implementation
- Document embedding and indexing
- Query understanding and processing
- Context-aware response generation
- Knowledge base integration
Advanced Processing
- Text chunking and processing
- Semantic similarity matching
- Context window management
- Response synthesis

Setup

Environment Configuration Create a .env file with the following variables:
OPENAI_API_KEY=your_openai_api_key VECTOR_DB_PATH=path_to_vector_database
Dependencies
pip install langchain openai chromadb sentence-transformers

Usage

Basic Information Retrieval

# Example: Simple query
query = "What are the key features of the system?"

# Example: Context-specific query
query = "How does the authentication system work?"

Advanced Retrieval

# Example: Multi-context query
query = {
    "question": "What are the system requirements?",
    "context": ["installation", "deployment", "configuration"]
}

# Example: Filtered retrieval
query = {
    "question": "Show me the API documentation",
    "filters": {
        "category": "api",
        "version": "2.0"
    }
}

How It Works

Query Processing
- Input query is received and preprocessed
- Query intent is analyzed
- Relevant context is identified
Information Retrieval
- Vector similarity search is performed
- Relevant documents are retrieved
- Context is assembled and ranked
Response Generation
- Retrieved information is processed
- Response is generated with context
- Results are formatted and returned

Performance Features

Error Handling

The system provides comprehensive error handling for:

Invalid queries
Missing context
Database connection issues
API rate limits
Processing errors

Best Practices

Query Formulation
- Be specific in your queries
- Provide relevant context
- Use appropriate filters
Context Management
- Keep context windows focused
- Update knowledge base regularly
- Monitor relevance scores
