📋 Understanding Composite Fields

Twenty CRM uses composite fields for related data. This server handles them automatically:

Name Composite

name: {
  firstName: "John",
  lastName: "Doe"
}

Emails Composite

emails: {
  primaryEmail: "[email protected]",
  additionalEmails: ["[email protected]"]
}

Phones Composite

phones: {
  primaryPhoneNumber: "5551234567",
  primaryPhoneCountryCode: "US",
  primaryPhoneCallingCode: "+1",
  additionalPhones: []
}

Address Composite

address: {
  addressStreet1: "123 Main St",
  addressStreet2: "Suite 100",
  addressCity: "San Francisco",
  addressPostcode: "94102",
  addressState: "CA",
  addressCountry: "United States"
}

Link Composite (LinkedIn, X, Domain)

linkedinLink: {
  primaryLinkUrl: "https://linkedin.com/in/user",
  secondaryLinks: []
}

Currency Composite (ARR)

annualRecurringRevenue: {
  amountMicros: 5000000000000,  // $5M stored as micros
  currencyCode: "USD"
}

Note: You provide simple values (e.g., email: "[email protected]"), and the server automatically structures them correctly for Twenty's API.

🏗️ Architecture

Why GraphQL?

This server uses GraphQL instead of REST because:

1. Better for nested objects - Twenty uses many composite fields
2. Type safety - GraphQL schema validation catches errors early
3. Flexible queries - Request exactly the fields you need
4. Clear error messages - Easier debugging
5. Future-proof - Easy to extend with new fields

Technical Stack

• MCP SDK - @modelcontextprotocol/sdk
• GraphQL - Direct integration with Twenty's GraphQL API
• Node.js - ES Modules, async/await
• TypeScript - Full type safety and IDE support
• Vitest - Fast unit testing with 71%+ code coverage
• Twenty CRM - Open-source CRM platform

🧪 Development & Testing

TypeScript Support

The server is written in TypeScript with comprehensive type definitions for:

• All API operations - Person and Company CRUD operations
• GraphQL requests - Full typing for queries and mutations
• Composite fields - Type-safe nested objects
• MCP protocol - Integration with the SDK's type system

Benefits:

• 🔒 Type-safe development with autocompletion
• 🐛 Catch errors at compile-time
• 📖 Self-documenting code with IntelliSense
• 🔄 Easy refactoring with confidence

Building from Source

# Build the TypeScript code
npm run build

# Start the compiled server
npm start

# Development mode with auto-reload
npm run dev

# Type-check without building
npm run type-check

Running Tests

The project includes comprehensive unit tests with 71%+ code coverage:

# Run all tests
npm test

# Watch mode for development
npm run test:watch

# Generate coverage report

• ✅ Composite field transformations (name, emails, phones, address, bodyV2)
• ✅ Currency conversion (ARR and opportunity amounts to micros)

Configuration Files

TypeScript:

• tsconfig.json - TypeScript compiler configuration
• src/index.ts - Main server implementation

Testing:

• vitest.config.ts - Test configuration
• src/index.test.ts - Comprehensive test suite

Build Output:

• dist/ - Compiled JavaScript and type definitions
• coverage/ - Test coverage reports

🐛 Troubleshooting

Connection Issues

Error: GraphQL request failed (404)

• Check TWENTY_BASE_URL is correct
• Self-hosted: Use your full domain (e.g., https://twenty.company.com)
• Cloud: Use https://api.twenty.com
• GraphQL endpoint is automatically set to ${TWENTY_BASE_URL}/graphql

Error: GraphQL request failed (401) or (403)

• Verify API key is correct
• Check API key has proper permissions in Twenty
• Generate a new API key in Settings → API & Webhooks

Field Validation Errors

Error: Field 'xyz' expected type 'ABC'

The server handles field transformations automatically. If you see validation errors:

1. Check the field name matches the API Reference
2. Ensure correct data types (string, number, boolean)
3. Review the GraphQL error message for specifics
4. Check the Examples section for correct usage

Records Not Appearing

Symptoms: No error but record doesn't appear in Twenty UI

Debug Steps:

1. Check the response - does it include an id?
2. Try fetching by ID: "Get person with ID xyz"
3. Refresh the Twenty CRM UI
4. Check Claude Desktop logs for hidden errors

🔄 Common Workflows

Onboarding New Clients

1. "Create a company called NewCo with domain newco.com"
2. "Create a person named John Smith, email [email protected], works at NewCo as CTO"
3. "Update NewCo's details: 10 employees, ARR $250k, mark as ideal customer profile"

Lead Management

1. "List all ideal customer profile companies"
2. "Find all contacts at [company name]"
3. "Update [person] with note about last call"

Data Enrichment

1. "List people without LinkedIn profiles"
2. "Update [person] LinkedIn: linkedin.com/in/username"
3. "List companies missing employee count"
