Extracts reusable MCP client logic into a separate package that can be shared across web UI, CLI, and TUI implementations. Includes: - MCP client lifecycle (createMcpClient, connectClient, disconnectClient) - HTTP transport creation (createHttpTransport, createAuthenticatedTransport) - Sampling/elicitation request handlers - Data layer interfaces (repositories, services) with memory stubs - Shared type definitions
- test-core.js: Unit tests for memory implementations (repositories, services, type helpers) - test-real-server.js: Integration tests with Everything MCP server Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
