Configuration

Environment Variables

All configuration is done through environment variables. Set these in your MCP server configuration.

Authentication

The MCP server uses JWT authentication with automatic token renewal:

1. Initial Authentication: On startup, the server authenticates using username/password

2. Token Storage: Access token is stored in memory

3. Automatic Renewal: Token is automatically renewed every 25 minutes (tokens expire after 30 minutes)

4. Manual Renewal: Use zerodb_renew_token to manually renew if needed

Security Best Practices

1. Store credentials securely: Use environment variables, never hardcode

2. Use project-specific credentials: Create separate projects for different applications

3. Rotate passwords regularly: Change passwords every 90 days

4. Monitor API usage: Check for unusual activity in project stats

5. Limit token scope: Use project-specific tokens when possible

Examples

Example 1: Building a Knowledge Base

// 1. Create a project for your knowledge base
const project = await zerodb_create_project({
  project_name: "Product Documentation KB",
  description: "Searchable product documentation"
});

// 2. Upload documentation files
const file = await zerodb_upload_file({
  file_name: "user_guide.pdf",
  file_data: "base64data...",
  content_type: "application/pdf"
});

// 3. Store vectors for semantic search
// (Assume you've generated embeddings from the documentation)
const vector = await zerodb_store_vector({
  vector_embedding: [...], // 1536-dimensional vector
  document: "How to reset your password: Navigate to Settings...",
  metadata: {
    source: "user_guide.pdf",
    page: 15
  }
});

// 4. Search the knowledge base
const results = await zerodb_search_vectors({
  query_vector: [...], // User query embedding
  limit: 5,
  threshold: 0.75
});

Example 2: Agent Memory with Context

// 1. Store conversation in memory
await zerodb_store_memory({
  content: "User wants to book a flight to Paris",
  role: "user",
  session_id: "session-123"
});

await zerodb_store_memory({
  content: "I'll help you book a flight to Paris. What dates?",
  role: "assistant",
  session_id: "session-123"
});

// 2. Later in the conversation, get context
const context = await zerodb_get_context({
  session_id: "session-123",
  max_tokens: 4096
});

// Context includes all previous messages, token-optimized

Example 3: RLHF Data Collection

// 1. Start RLHF collection for session
await zerodb_rlhf_start({
  session_id: "session-456",
  collection_config: {
    collect_all_interactions: true
  }
});

// 2. Collect interactions during conversation
await zerodb_rlhf_interaction({
  session_id: "session-456",
  user_input: "What's the weather like?",
  agent_response: "I don't have access to real-time weather data",
  feedback_score: 3,
  metadata: {
    model: "claude-3-sonnet",
    response_time_ms: 800
  }
});

// 3. Collect error reports
await zerodb_rlhf_error({
  session_id: "session-456",
  error_type: "capability_limitation",
  error_message: "Agent cannot access real-time data",
  user_impact: "medium"
});

// 4. Get RLHF summary
const summary = await zerodb_rlhf_summary({
  group_by: "session",
  start_date: "2025-10-14T00:00:00Z"
});

Example 4: Quantum-Enhanced Search

// 1. Store vectors with quantum compression
const compressed = await zerodb_quantum_compress({
  vector_embedding: [...], // Original 1536 dimensions
  compression_ratio: 0.5,
  algorithm: "qaoa"
});

// Store compressed version
await zerodb_store_vector({
  vector_embedding: compressed.compressed_vector,
  document: "Product description...",
  metadata: {
    compressed: true,
    original_dimensions: 1536
  }
});

// 2. Perform quantum hybrid search
const results = await zerodb_quantum_hybrid_search({
  query_vector: [...],
  quantum_weight: 0.7, // Higher weight for quantum similarity
  limit: 10
});

// Results include both classical and quantum similarity scores

Example 5: NoSQL Data Management

// 1. Create a table for user profiles
const table = await zerodb_create_table({
  table_name: "user_profiles",
  schema: {
    user_id: "uuid",
    name: "string",
    email: "string",
    preferences: "json",
    created_at: "timestamp"
  }
});

// 2. Insert user data
await zerodb_insert_rows({
  table_id: table.table_id,
  rows: [
    {
      user_id: "user-1",
      name: "Alice Smith",
      email: "alice@example.com",
      preferences: { theme: "dark", language: "en" }
    }
  ]
});

// 3. Query users
const users = await zerodb_query_rows({
  table_id: table.table_id,
  filters: {
    email: { $contains: "@example.com" }
  }
});

// 4. Update preferences
await zerodb_update_rows({
  table_id: table.table_id,
  filters: { user_id: "user-1" },
  updates: {
    preferences: { theme: "light", language: "en" }
  }
});

Example 6: Error Handling

// All operations return structured responses with error handling
try {
  const result = await zerodb_store_vector({
    vector_embedding: [...],
    document: "Sample text"
  });

  if (result.isError) {
    console.error("Operation failed:", result.content[0].text);
    // Handle error appropriately
  } else {
    console.log("Success:", result.content[0].text);
  }
} catch (error) {
  // Handle unexpected errors
  console.error("Unexpected error:", error.message);
}

Migration Guide

Migrating from v1.x to v2.0.0

Breaking Changes

1. API Endpoint Consolidation

   • v1.x: Direct API calls to various endpoints

   • v2.0: All operations go through unified MCP execute endpoint

   Impact: No code changes needed if using MCP tools

2. Tool Naming Convention

   • v1.x: Some tools lacked zerodb_ prefix

   • v2.0: All tools prefixed with zerodb_

   Migration:

   // Old (v1.x)
   store_memory(...) → zerodb_store_memory(...)
   search_memory(...) → zerodb_search_memory(...)
   
   // New (v2.0)
   zerodb_store_memory(...) // Consistent prefix

3. Parameter Changes

   • Memory operations: memory_metadata → metadata

   • Vector operations: vector_metadata → metadata

   Migration:

   // Old (v1.x)
   {
     content: "...",
     memory_metadata: { key: "value" }
   }
   
   // New (v2.0)
   {
     content: "...",
     metadata: { key: "value" }
   }

4. New Required Environment Variables

   • ZERODB_PROJECT_ID is now required (was optional in v1.x)

   Migration: Add to your config:

   {
     "env": {
       "ZERODB_PROJECT_ID": "your-project-id"
     }
   }

Troubleshooting

Common Issues

1. Authentication Failed

Error: Authentication failed: Invalid credentials

Solutions:

• Verify ZERODB_USERNAME and ZERODB_PASSWORD are correct

• Check that your account is active

• Try manual token renewal: zerodb_renew_token

2. Project Not Found

Error: Project not found: [project-id]

Solutions:

• Verify ZERODB_PROJECT_ID is correct

• List your projects: zerodb_list_projects

• Create a new project: zerodb_create_project

3. Vector Dimension Mismatch

Error: vector must have exactly 1536 dimensions, got 768

Solutions:

• Ensure you're using OpenAI's text-embedding-3-small (1536 dimensions)

• Or use text-embedding-ada-002 (1536 dimensions)

• Do not use text-embedding-3-large (3072 dimensions)

4. Token Expired

Error: Token expired or invalid

Solutions:

• The server should auto-renew tokens every 25 minutes

• Manually renew: zerodb_renew_token

• Check server logs for renewal errors

5. Rate Limiting

Error: Rate limit exceeded

Solutions:

• Reduce request frequency

• Use batch operations where available

• Contact support for rate limit increases

Debug Logging

Enable verbose logging by checking stderr output:

# The MCP server logs to stderr
# In Claude Desktop, check: ~/Library/Logs/Claude/mcp*.log

Log messages include:

• Token renewal attempts and status

• API call details (operation, params)

• Error messages with full context
