It provides a complete implementation for template CRUD operations, block manipulation, HTML rendering, persistent storage, and resource previews. The changes include new documentation, configuration, and a fully structured codebase for the server.

• Added @usewaypoint/mcp-server package with full MCP server setup, tool registration for template and block operations, and resource handling for HTML previews. (packages/mcp-server/src/server.ts, packages/mcp-server/src/index.ts) [1] [2]

Persistent Template Storage

• Implemented file-based template storage with in-memory caching, supporting creation, update, deletion, and listing of templates in the user's home directory. (packages/mcp-server/src/services/template-storage.ts)

HTML Rendering and Resource Previews

• Added server-side HTML rendering for templates and resource endpoints to preview templates via a resource URI. (packages/mcp-server/src/services/renderer.ts, packages/mcp-server/src/resources/template-preview.ts, packages/mcp-server/src/resources/index.ts) [1] [2] [3]

Documentation and Configuration:

Comprehensive Documentation

• Added detailed README.md for the MCP server package, covering usage, architecture, available tools/resources, and development workflow. (packages/mcp-server/README.md)
• Added CLAUDE.md to guide usage with Claude Code, including build/test commands, architecture overview, and code style.

Package Setup
