Overview

Prometh Cortex is a local-first, extensible system for indexing multiple datalake repositories containing Markdown files and exposing their content for retrieval-augmented generation (RAG) workflows through a local MCP (Modular Command Processor) server.

Features

• Multi-Datalake Support: Index multiple repositories of Markdown documents
• YAML Frontmatter Parsing: Rich metadata extraction with structured schema support
• Dual Vector Store Support: Choose between local FAISS or cloud-native Qdrant
• Incremental Indexing: Smart change detection for efficient updates
• MCP Server: Local server compatible with Claude, VSCode, and other tools
• CLI Interface: Easy-to-use command line tools for indexing and querying
• Performance Optimized: Target <100ms query response time on M1/M2 Mac

Installation

From PyPI (Recommended)

pip install prometh-cortex

From Source (Development)

git clone https://github.com/ivannagy/prometh-cortex.git
cd prometh-cortex
pip install -e ".[dev]"

Quick Start

1. Install via pip:

pip install prometh-cortex

2. Initialize configuration (creates ~/.config/prometh-cortex/config.toml):

pcortex config --init

3. Edit your config file:

# macOS/Linux
nano ~/.config/prometh-cortex/config.toml

# Or use your preferred editor
# Update the [datalake] repos with your document paths

4. Build index:

pcortex build

5. Query locally:

pcortex query "search for something"

6. Start servers:

# For Claude Desktop (MCP protocol)
pcortex mcp

# For Perplexity/VSCode/HTTP integrations
pcortex serve

Configuration File Locations

Prometh-cortex follows the XDG Base Directory Specification. Config files are searched in this order:

1. ./config.toml - Current directory (highest priority)
2. ~/.config/prometh-cortex/config.toml - XDG config directory (recommended)
3. ~/.prometh-cortex/config.toml - Fallback location

Useful commands:

# Initialize config in XDG directory (recommended for system-wide use)
pcortex config --init

# Create sample config in current directory (for project-specific config)
pcortex config --sample

# Show all config search paths
pcortex config --show-paths

Configuration

Create a config.toml file with your settings:

cp config.toml.sample config.toml
# Edit config.toml with your specific paths and settings

Configuration Format (TOML)

[datalake]
# Add your document directories here
repos = [
    "/path/to/your/notes",
    "/path/to/your/documents", 
    "/path/to/your/projects"
]

[storage]
rag_index_dir = "/path/to/index/storage"

[server]
port = 8080
host = "localhost"
auth_token = "your-secure-token"

[embedding]
model = "sentence-transformers/all-MiniLM-L6-v2"
max_query_results = 10
chunk_size = 512
chunk_overlap = 50

[vector_store]
type = "faiss"  # or "qdrant"

# Qdrant configuration (when type = "qdrant")
[vector_store.qdrant]
host = "localhost"
port = 6333
collection_name = "prometh_cortex"

Vector Store Configuration

Prometh Cortex supports two vector store backends:

Option 1: FAISS (Default - Local Storage)

Best for: Local development, private deployments, no external dependencies

[vector_store]
type = "faiss"

[storage]
rag_index_dir = ".rag_index"

Advantages:

• ✅ No external dependencies
• ✅ Fast local queries
• ✅ Works offline
• ✅ Simple setup

Disadvantages:

• ❌ Limited to single machine
• ❌ No concurrent write access
• ❌ Manual backup required

Option 2: Qdrant (Cloud-native Vector Database)

Best for: Production deployments, team collaboration, scalable solutions

Local Qdrant with Docker

# Start Qdrant container with persistent storage
docker run -d \
  --name qdrant \
  -p 6333:6333 \
  -v $(pwd)/qdrant_storage:/qdrant/storage \
  qdrant/qdrant

[vector_store]
type = "qdrant"

[vector_store.qdrant]
host = "localhost"
port = 6333
collection_name = "prometh_cortex"

Cloud Qdrant

[vector_store]
type = "qdrant"

[vector_store.qdrant]
host = "your-cluster.qdrant.io"
port = 6333
collection_name = "prometh_cortex"
api_key = "your-api-key-here"
use_https = true

Advantages:

• ✅ Concurrent access support
• ✅ Built-in clustering and replication
• ✅ Advanced filtering capabilities
• ✅ REST API access
• ✅ Automatic backups (cloud)
• ✅ Horizontal scaling

Disadvantages:

• ❌ Requires external service
• ❌ Network dependency
• ❌ Additional complexity

Qdrant Setup Steps

1. Local Docker Setup:

   host = "localhost"
   port = 6333
   collection_name = "prometh_cortex"</p>
   <h1>api_key = ""  # Optional for local Docker</h1>
   <h1>use_https = false  # Default for local</h1>
   <pre><code>
   3. **Build Index**:
   ```bash
   # Initial build or incremental update
   pcortex build
   
   # Force complete rebuild
   pcortex rebuild --confirm
   

   4. Verify Setup:

      # Check health and statistics
      pcortex query "test" --max-results 1

      <pre><code>
      #### Migration Between Vector Stores
      
      ```bash
      # Backup current index (if using FAISS)
      pcortex build --backup /tmp/backup_$(date +%Y%m%d_%H%M%S)
      
      # Change vector store type in config.toml
      sed -i 's/type = "faiss"/type = "qdrant"/' config.toml
      
      # Rebuild index with new vector store
      pcortex rebuild --confirm
      
      # Verify migration successful
      pcortex query "test migration" --max-results 1
      

      CLI Commands

      YAML Frontmatter Best Practices

      ⚠️ Important: When using special characters in YAML values, always quote them properly to ensure correct parsing:

      ✅ Correct Usage:

      ---
      title: "[PRJ-0119] Add New Feature"    # Quoted because of brackets
      author: "John O'Connor"                # Quoted because of apostrophe
      tags:
        - "C#"                               # Quoted because of hash symbol
        - "project-2024"                     # Safe without quotes
      category: "Work & Personal"            # Quoted because of ampersand
      ---
      

      ❌ Problematic Usage:

      ---
      title: [PRJ-0119] Add New Feature      # Brackets will cause parsing errors
      author: John O'Connor                  # Apostrophe may cause issues
      tags:
        - C#                                 # Hash symbol conflicts with YAML
      category: Work & Personal              # Ampersand may cause issues  
      ---
      

      Common Characters That Need Quoting:

      • Square brackets []: title: "[PROJECT-123] Task Name"
      • Curly braces {}: status: "{COMPLETED}"
      • Hash/Pound #: tag: "C#"
      • Colon :: note: "Time: 3:30 PM"
      • Ampersand &: title: "Sales & Marketing"
      • Asterisk *: priority: "*HIGH*"
      • Pipe |: command: "grep | sort"
      • Greater/Less than <>: comparison: "<100ms"
      • At symbol @: email: "@company.com"
      • Apostrophes ': name: "O'Connor"

      Why This Matters:

      • Metadata Parsing: Improper YAML syntax prevents frontmatter from being extracted
      • Index Quality: Missing metadata means poor search results and filtering
      • Qdrant Storage: Malformed YAML leads to incomplete document payloads
      • Search Performance: Documents without proper metadata are harder to find

      Validation:

      Test your YAML frontmatter before indexing:

      # Quick validation of a document
      python -c "
      import yaml
      import frontmatter
      
      with open('your-document.md', 'r') as f:
          post = frontmatter.load(f)
          print('✅ YAML parsed successfully')
          print(f'Title: {post.metadata.get(\"title\", \"N/A\")}')
          print(f'Fields: {list(post.metadata.keys())}')
      "
      

      Integration

      Claude Desktop Integration

      Configure Claude Desktop by editing ~/Library/Application Support/Claude/claude_desktop_config.json:

      {
        "mcpServers": {
          "prometh-cortex": {
            "command": "/path/to/your/project/.venv/bin/python",
            "args": [
              "-m", "prometh_cortex.cli.main", "mcp"
            ],
            "env": {
              "DATALAKE_REPOS": "/path/to/your/notes,/path/to/your/documents,/path/to/your/projects",
              "RAG_INDEX_DIR": "/path/to/index/storage",
              "MCP_PORT": "8080",
              "MCP_HOST": "localhost",
              "MCP_AUTH_TOKEN": "your-secure-token",
              "EMBEDDING_MODEL": "sentence-transformers/all-MiniLM-L6-v2",
              "MAX_QUERY_RESULTS": "10",
              "CHUNK_SIZE": "512",
              "CHUNK_OVERLAP": "50",
              "VECTOR_STORE_TYPE": "faiss"
            }
          }
        }
      }
      

      Setup Steps:

      1. Install in Virtual Environment:

         cd /path/to/prometh-cortex
         python -m venv .venv
         source .venv/bin/activate  # On macOS/Linux
         pip install -e .
         

      2. Configure Settings: Create and customize your configuration:

         # Create configuration file
         cp config.toml.sample config.toml
         
         # Edit config.toml with your specific paths and settings
         # Update the [datalake] repos array with your document directories
         # Set your preferred [storage] rag_index_dir location
         # Customize [server] auth_token for security
         

      3. Build your index:

         source .venv/bin/activate
         pcortex build --force
         

      4. Get Absolute Paths: Update the MCP configuration with your actual paths:

         # Get your virtual environment Python path
         which python  # While .venv is activated
         
         # Get your project directory
         pwd
         

      5. Update Claude Desktop Config: Use absolute paths in your claude_desktop_config.json:

         {
           "mcpServers": {
             "prometh-cortex": {
               "command": "/path/to/your/project/.venv/bin/python",
               "args": [
                 "-m", "prometh_cortex.cli.main", "mcp"
               ],
               "env": {
                 "DATALAKE_REPOS": "/path/to/your/notes,/path/to/your/documents,/path/to/your/projects",
                 "RAG_INDEX_DIR": "/path/to/index/storage",
                 "MCP_PORT": "8080",
                 "MCP_HOST": "localhost",
                 "MCP_AUTH_TOKEN": "your-secure-token",
                 "EMBEDDING_MODEL": "sentence-transformers/all-MiniLM-L6-v2",
                 "MAX_QUERY_RESULTS": "10",
                 "CHUNK_SIZE": "512",
                 "CHUNK_OVERLAP": "50"
               }
             }
           }
         }
         

      6. Verify Configuration:

         # Test MCP server manually
         source .venv/bin/activate
         pcortex mcp  # Should start without errors
         

      7. Restart Claude Desktop: Completely quit and restart Claude Desktop application.

      Troubleshooting:

      • ✅ Check Logs: Look at Claude Desktop console logs for MCP connection errors
      • ✅ Verify Paths: Ensure all paths in the config are absolute and correct
      • ✅ Test Index: Run pcortex query "test" to verify your index works
      • ✅ Environment: Make sure environment variables are accessible from the MCP context

      Usage: After restarting Claude Desktop, you'll have access to these MCP tools:

      • prometh_cortex_query: Search your indexed documents
        • Ask: "Search my notes for yesterday's meetings"
        • Ask: "Find documents about project planning"
        • Ask: "What meetings did I have last week?"
      • prometh_cortex_health: Check system status
        • Ask: "How many documents are indexed in prometh-cortex?"
        • Ask: "What's the health status of my knowledge base?"

      Claude.ai Web Integration

      Configure Claude.ai to use your MCP server by adding it as a custom integration:

      1. Start your MCP server: pcortex serve
      2. Use the webhook URL: http://localhost:8080/prometh_cortex_query
      3. Set authentication header: Authorization: Bearer your-secret-token
      4. Send queries in JSON format:

         {
           "query": "search term",
           "max_results": 10
         }
         

      Perplexity Integration

      Configure Perplexity to use your local MCP server for document search:

      Prerequisites:

      1. Start HTTP Server (not MCP protocol):

         source .venv/bin/activate
         pcortex serve --port 8001  # Use different port than MCP
         

      2. Configure for Performance (important for Perplexity timeouts):

         </code></pre>
         </li>
         </ol>
         <h1>Edit your config.toml for faster responses</h1>
         <h1>In the [embedding] section, set:</h1>
         <h1>max_query_results = 3  # Reduce from default 10 to 3</h1>
         <pre><code>
         3. **Verify Health**:
         ```bash
         curl -H "Authorization: Bearer your-secret-token" \
              http://localhost:8001/prometh_cortex_health
         

         Integration Setup:

         1. Server Configuration:

            • Protocol: HTTP
            • URL: http://localhost:8001/prometh_cortex_query
            • Method: POST
            • Headers: Authorization: Bearer your-secret-token
            • Content-Type: application/json

         2. Query Format:

            {
              "query": "your search query",
              "max_results": 3
            }
            

         3. Example Request:

            curl -X POST http://localhost:8001/prometh_cortex_query \
              -H "Authorization: Bearer your-secret-token" \
              -H "Content-Type: application/json" \
              -d '{"query": "meeting notes", "max_results": 3}'
            

         Performance Optimization:

         • ✅ Reduced Results: Use max_results: 3 instead of 10 to avoid timeouts
         • ✅ Dedicated Port: Use separate port (8001) for Perplexity vs other integrations
         • ✅ Quick Queries: Response time optimized to <400ms for timeout compatibility

         Usage in Perplexity:

         • Ask: "Search my local documents for project updates"
         • Ask: "Find my notes about last week's meetings"
         • Ask: "What information do I have about [specific topic]?"

         VSCode with GitHub Copilot Integration

         Configure VSCode to use your MCP server with GitHub Copilot:

         Option 1: VSCode MCP Extension (Recommended)

         1. Install MCP for VSCode:

            # Install the VSCode MCP extension
            code --install-extension ms-vscode.mcp
            

         2. Configure MCP Settings: Add to your VSCode settings.json or create .vscode/mcp.json:

            {
              "mcpServers": {
                "prometh-cortex": {
                  "command": "/path/to/your/project/.venv/bin/python",
                  "args": [
                    "-m", "prometh_cortex.cli.main", "mcp"
                  ],
                  "env": {
                    "DATALAKE_REPOS": "/path/to/your/notes,/path/to/your/documents,/path/to/your/projects",
                    "RAG_INDEX_DIR": "/path/to/index/storage",
                    "MCP_PORT": "8080",
                    "MCP_HOST": "localhost",
                    "MCP_AUTH_TOKEN": "your-secure-token",
                    "EMBEDDING_MODEL": "sentence-transformers/all-MiniLM-L6-v2",
                    "MAX_QUERY_RESULTS": "10",
                    "CHUNK_SIZE": "512",
                    "CHUNK_OVERLAP": "50"
                  }
                }
              }
            }
            

         3. Update User Settings: Add to your VSCode settings.json:

            {
              "mcp.servers": {
                "prometh-cortex": {
                  "enabled": true
                }
              }
            }
            

         4. Verify Integration:

            • Open Command Palette (Cmd+Shift+P)
            • Run "MCP: List Servers"
            • You should see "prometh-cortex" listed and active

         Option 2: Direct HTTP Integration

         Add to your VSCode settings.json:

         {
           "github.copilot.advanced": {
             "debug.useElectronPrompts": true,
             "debug.useNodeUserForPrompts": true
           },
           "prometh-cortex.server.url": "http://localhost:8001",
           "prometh-cortex.server.token": "your-secret-token"
         }
         

         Start the HTTP server:

         source .venv/bin/activate
         pcortex serve --port 8001
         

         Option 3: Custom Task Integration

         Create .vscode/tasks.json for quick queries:

         {
           "version": "2.0.0",
           "tasks": [
             {
               "label": "Query Prometh-Cortex",
               "type": "shell",
               "command": "curl",
               "args": [
                 "-H", "Authorization: Bearer your-secret-token",
                 "-H", "Content-Type: application/json",
                 "-d", "{\"query\": \"${input:searchQuery}\", \"max_results\": 5}",
                 "http://localhost:8001/prometh_cortex_query"
               ],
               "group": "build",
               "presentation": {
                 "echo": true,
                 "reveal": "always",
                 "panel": "new"
               }
             }
           ],
           "inputs": [
             {
               "id": "searchQuery",
               "description": "Enter your search query",
               "default": "meeting notes",
               "type": "promptString"
             }
           ]
         }
         

         Setup Steps:

         1. Build Index: Ensure your RAG index is built and up-to-date

            source .venv/bin/activate
            pcortex build --force
            

         2. Start MCP Server (for Option 1):

            # MCP server runs automatically when VSCode starts
            # Check VSCode Output panel for MCP logs
            

         3. Start HTTP Server (for Options 2-3):

            source .venv/bin/activate
            pcortex serve --port 8001
            

         Usage:

         • Option 1: Use MCP commands directly in GitHub Copilot chat
           • Ask: "Search my documents for project planning notes"
           • Ask: "Find my meeting notes from last week"
         • Option 2: GitHub Copilot will automatically query your local documents
         • Option 3: Press Ctrl+Shift+P → "Tasks: Run Task" → "Query Prometh-Cortex"

         Troubleshooting:

         • ✅ Check MCP Output: View "Output" panel in VSCode, select "MCP" from dropdown
         • ✅ Verify Paths: Ensure all paths are absolute and accessible
         • ✅ Test Manually: Run pcortex mcp or pcortex serve to verify functionality
         • ✅ Restart VSCode: After configuration changes, restart VSCode completely "inputs": [ { "id": "searchQuery", "description": "Enter your search query", "default": "meeting notes", "type": "promptString" } ] }

         
         **Usage**: Press `Ctrl+Shift+P` → "Tasks: Run Task" → "Query Prometh-Cortex"
         
         ### General MCP Configuration Guide
         
         **Two Server Types Available**:
         
         1. **MCP Protocol Server** (`pcortex mcp`):
            - **Purpose**: AI assistant integration (Claude Desktop, VSCode MCP)
            - **Protocol**: stdio-based MCP
            - **Port**: No network port (stdio communication)
            - **Usage**: Direct integration with MCP-compatible clients
         
         2. **HTTP REST Server** (`pcortex serve`):
            - **Purpose**: Web applications, HTTP clients (Perplexity, custom integrations)
            - **Protocol**: HTTP REST API
            - **Port**: Configurable (default: 8080)
            - **Usage**: Traditional HTTP API access
         
         **Configuration Prerequisites**: 
         
         1. **Environment Setup**:
            ```bash
            # Create and activate virtual environment
            python -m venv .venv
            source .venv/bin/activate  # macOS/Linux
            
            # Install in development mode
            pip install -e .
         

         2. Create Configuration:

            # Create configuration from sample
            cp config.toml.sample config.toml
            # Edit config.toml with your specific settings
            

         3. Build Index:

            pcortex build --force
            

         4. Test Configuration:

            # Test MCP server
            pcortex mcp  # Should start without errors, Ctrl+C to stop
            
            # Test HTTP server
            pcortex serve  # Should show server info, Ctrl+C to stop
            
            # Test query functionality
            pcortex query "test search"
            

         Common Integration Pattern:

         For HTTP integrations (Perplexity, web apps):

         # Start HTTP server
         pcortex serve --port 8001
         
         # Query endpoint
         POST http://localhost:8001/prometh_cortex_query
         Authorization: Bearer your-secret-token
         Content-Type: application/json
         
         {
           "query": "your search query",
           "max_results": 10,
           "filters": {
             "datalake": "notes",
             "tags": ["work"]
           }
         }
         
         # Health check
         GET http://localhost:8001/prometh_cortex_health
         Authorization: Bearer your-secret-token
         

         For MCP integrations (Claude Desktop, VSCode):

         {
           "mcpServers": {
             "prometh-cortex": {
               "command": "/path/to/your/project/.venv/bin/python",
               "args": [
                 "-m", "prometh_cortex.cli.main", "mcp"
               ],
               "env": {
                 "DATALAKE_REPOS": "/path/to/your/notes,/path/to/your/documents,/path/to/your/projects",
                 "RAG_INDEX_DIR": "/path/to/index/storage",
                 "MCP_PORT": "8080",
                 "MCP_HOST": "localhost",
                 "MCP_AUTH_TOKEN": "your-secure-token",
                 "EMBEDDING_MODEL": "sentence-transformers/all-MiniLM-L6-v2",
                 "MAX_QUERY_RESULTS": "10",
                 "CHUNK_SIZE": "512",
                 "CHUNK_OVERLAP": "50",
                 "VECTOR_STORE_TYPE": "faiss"
               }
             }
           }
         }
         

         Performance Tuning:

         • For Perplexity: Set max_query_results = 3 in config.toml to avoid timeouts
         • For Development: Use --reload flag with pcortex serve
         • For Production: Use production WSGI server instead of development server

         Auto-start Script: Create start_servers.sh for easy management:

         #!/bin/bash
         # Kill existing servers
         pkill -f "pcortex serve" 2>/dev/null || true
         pkill -f "pcortex mcp" 2>/dev/null || true
         
         # Activate virtual environment
         source .venv/bin/activate
         
         # Start HTTP server in background
         nohup pcortex serve --port 8001 > /tmp/prometh-cortex-http.log 2>&1 &
         
         echo "Prometh-Cortex servers started"
         echo "HTTP Server: http://localhost:8001"
         echo "MCP Server: Available for stdio connections"
         echo "Logs: /tmp/prometh-cortex-http.log"
         

         Troubleshooting Checklist:

         • ✅ Virtual Environment: Always use absolute paths to .venv/bin/python
         • ✅ Configuration: Set datalake.repos and storage.rag_index_dir in config.toml
         • ✅ Index Built: Run pcortex build before using servers
         • ✅ Ports Available: Check port conflicts with lsof -i :8080
         • ✅ Logs Check: Monitor server logs for configuration errors
         • ✅ Path Permissions: Ensure read access to datalake and write access to index directory
