Development Commands

• pnpm install - Install all dependencies
• pnpm build - Build all servers
• pnpm start:attio - Start the Attio server locally
• pnpm start:graphql - Start the GraphQL server locally
• pnpm start:motherduck - Start the MotherDuck server locally
• pnpm start:neo4j - Start the Neo4j server locally
• pnpm clean - Clean all build artifacts and dependencies

Local Development

Each server can be developed independently:

1. Clone the repository
2. Install dependencies with pnpm install
3. Configure environment variables for the target server
4. Run the specific server using the commands above

Getting Started

Each server includes detailed setup instructions in its individual README:

• Attio: Requires Attio API key from workspace settings
• GraphQL: Supports various authentication methods per API
• MotherDuck: Requires MotherDuck access token
• Neo4j: Requires Neo4j connection details via headers

Refer to individual server documentation for complete setup guides, authentication details, and usage examples.
