Overview

This package provides pure type definitions with no side effects. All implementations should depend on these core types.

Dependency Direction

The dependency flow must be strictly maintained:

core → runtime → transport → server → mcp-hub

Contents

• Types: Core type definitions for connections, sessions, and registries
• Errors: Error codes and severity levels
• Events: Event contracts for server lifecycle, discovery, and sessions
• Protocol: MCP protocol definitions and constants

Usage

import { ErrorCode, ConnectionType, EventName } from '@himorishige/hatago-core';

// Use types in your implementation
const connectionType: ConnectionType = 'local';
