🔧 Configuration

Configuration File

Create a ruvector.toml configuration file for default settings:

[database]
storage_path = "./ruvector.db"
dimensions = 384
distance_metric = "Cosine"  # Cosine, Euclidean, DotProduct, Manhattan

[database.hnsw]
m = 16
ef_construction = 200
ef_search = 100

[database.quantization]
type = "Scalar"  # Scalar, Product, or None

[cli]
progress = true
colors = true
batch_size = 1000

[mcp]
host = "127.0.0.1"
port = 3000
cors = true

Configuration Locations

The CLI searches for configuration files in this order:

Path specified via --config flag
./ruvector.toml (current directory)
./.ruvector.toml (current directory, hidden)
~/.config/ruvector/config.toml (user config)
/etc/ruvector/config.toml (system config)

Environment Variables

Override configuration with environment variables:

# Database settings
export RUVECTOR_STORAGE_PATH="./my-db.db"
export RUVECTOR_DIMENSIONS=384
export RUVECTOR_DISTANCE_METRIC="cosine"

# MCP server settings
export RUVECTOR_MCP_HOST="0.0.0.0"
export RUVECTOR_MCP_PORT=3000

# Run with environment overrides
ruvector info

🔌 MCP Server

The Ruvector CLI includes a Model Context Protocol (MCP) server for AI agent integration.

Start MCP Server

STDIO Transport (for local AI tools):

ruvector-mcp --transport stdio

SSE Transport (for web-based AI tools):

ruvector-mcp --transport sse --host 0.0.0.0 --port 3000

With Configuration:

ruvector-mcp --config ./ruvector.toml --transport sse --debug

MCP Integration Examples

Claude Desktop Integration (claude_desktop_config.json):

{
  "mcpServers": {
    "ruvector": {
      "command": "ruvector-mcp",
      "args": ["--transport", "stdio"],
      "env": {
        "RUVECTOR_STORAGE_PATH": "/path/to/vectors.db"
      }
    }
  }
}

HTTP/SSE Client:

const evtSource = new EventSource('http://localhost:3000/sse');

evtSource.addEventListener('message', (event) => {
  const data = JSON.parse(event.data);
  console.log('MCP Response:', data);
});

// Send search request
fetch('http://localhost:3000/mcp', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    method: 'search',
    params: {
      query: [0.1, 0.2, 0.3],
      k: 10
    }
  })
});

📊 Common Workflows

RAG System Setup

Build a retrieval-augmented generation (RAG) system:

# 1. Create database for your embedding model
ruvector create --dimensions 384 --path ./rag-embeddings.db

# 2. Generate embeddings and save to JSON
# (Use your preferred embedding model)

# 3. Insert embeddings
ruvector insert --db ./rag-embeddings.db --input embeddings.json

# 4. Query for relevant context
ruvector search --db ./rag-embeddings.db \
  --query "[0.123, 0.456, ...]" \
  --top-k 5

# 5. Start MCP server for AI agent access
ruvector-mcp --transport stdio

Semantic Search Engine

Build a semantic search system:

# Create database
ruvector create --dimensions 768 --path ./search-engine.db

# Batch insert documents
ruvector insert \
  --db ./search-engine.db \
  --input documents.json \
  --format json

# Benchmark performance
ruvector benchmark --db ./search-engine.db --queries 10000

# Search interface via MCP
ruvector-mcp --transport sse --port 8080

Migration from Other Databases

Migrate from existing vector databases:

# 1. Export from source database
# (Use source database's export tools)

# 2. Create Ruvector database
ruvector create --dimensions 1536 --path ./migrated.db

# 3. Import data (planned feature)
ruvector import \
  --db ./migrated.db \
  --source pinecone \
  --source-path ./pinecone-export.json

# 4. Verify migration
ruvector info --db ./migrated.db
ruvector benchmark --db ./migrated.db

Performance Testing

Test vector database performance:

# Create test database
ruvector create --dimensions 384 --path ./benchmark.db

# Generate synthetic test data
python generate_test_vectors.py --count 100000 --dims 384 --output test.npy

# Insert test data
ruvector insert --db ./benchmark.db --input test.npy --format npy

# Run comprehensive benchmark
ruvector benchmark --db ./benchmark.db --queries 10000

# Test search performance
time ruvector search --db ./benchmark.db --query "[0.1, 0.2, ...]" -k 100

🎯 Shell Completion

Generate shell completion scripts for faster command entry:

Bash

# Generate completion script
ruvector --help > /dev/null  # Trigger clap completion
complete -C ruvector ruvector

# Or add to ~/.bashrc
echo 'complete -C ruvector ruvector' >> ~/.bashrc

Zsh

# Add to ~/.zshrc
autoload -U compinit && compinit
complete -o nospace -C ruvector ruvector

Fish

# Generate and save completion
ruvector --help > /dev/null
complete -c ruvector -f

⚙️ Performance Tips

Optimize Insertion

# Use larger batch sizes for bulk inserts (set in config)
[cli]
batch_size = 10000

# Disable progress bar for maximum speed
ruvector insert --input large-file.json --no-progress

Optimize Search

Configure HNSW parameters for your use case:

[database.hnsw]
# Higher M = better recall, more memory
m = 32

# Higher ef_construction = better index quality, slower builds
ef_construction = 400

# Higher ef_search = better recall, slower queries
ef_search = 200

Memory Optimization

Enable quantization to reduce memory usage:

[database.quantization]
type = "Product"  # 4-8x memory reduction

Benchmarking Tips

# Run warm-up queries first
ruvector search --query "[...]" -k 10
ruvector search --query "[...]" -k 10

# Then benchmark
ruvector benchmark --queries 10000

# Test different k values
for k in 10 50 100; do
  time ruvector search --query "[...]" -k $k
done

🐛 Troubleshooting

Common Issues

Database file not found:

# Ensure database exists
ruvector info --db ./ruvector.db

# Or create it first
ruvector create --dimensions 384 --path ./ruvector.db

Dimension mismatch:

# Error: "Vector dimension mismatch"
# Solution: Ensure all vectors match database dimensions

# Check database dimensions
ruvector info --db ./ruvector.db

Invalid query format:

# Use proper JSON or comma-separated format
ruvector search --query "[0.1, 0.2, 0.3]"  # JSON
ruvector search --query "0.1, 0.2, 0.3"    # CSV

MCP server connection issues:

# Check if port is available
lsof -i :3000

# Try different port
ruvector-mcp --transport sse --port 8080

# Enable debug logging
ruvector-mcp --transport sse --debug
