v0.4.0

Breaking Changes

• Configuration system completely revamped - now uses object-based config, instead of file-based
  • Config structure is based on on emergent mcpServers config "standard" used by Claude, Claude Code, and many other MCP clients
• MultiServerMCPClient constructor now requires a connections record or complete server config, and no longer auto-loads from mcp.json
• Several methods that were sync are now async (e.g., getTools(), getClient())
• Removed multiple configuration methods (fromConfigFile, addConfigFromFile, etc.)
• Added Zod validation for configurations with improved error reporting
• Changed tool naming convention for MultiServerMCPClient with new prefix options, aligned with naming conventions used by Claude Code

New Features

• Support for rich content responses including text, images, and embedded resources
• Added debug logging with the debug package
• Improved error handling with distinct error types
• More robust type safety throughout the codebase

Documentation

• Completely restructured README with clearer examples and organization
• Added detailed sections on configuration options, error handling, and response types
• Simplified examples focused on real-world use cases
