For Developers

Development Commands

  • pnpm install - Install dependencies

  • pnpm run build - Build the project for HTTP streaming (default)

  • pnpm run dev - Run in development mode with hot reloading

  • pnpm run inspector - Launch MCP inspector for testing (stdio mode)

  • pnpm run test - Run tests

Deployment Options

HTTP Streaming (Recommended)

pnpm run build:http pnpm run start:http

Traditional stdio (Legacy)

pnpm run build:stdio pnpm run start:stdio

The HTTP streaming interface offers better performance and simplified deployment without requiring Docker, while maintaining full backwards compatibility with the traditional stdio interface.
