feat(debug-server): add interactive debug server example#321
Merged
Conversation
A comprehensive debug/development server for testing MCP Apps SDK features: - Vanilla TypeScript UI with collapsible panels - Message visualization (sent, received, errors) - Server tool calling interface - Multiple tool endpoints for testing
- Replace vanilla TypeScript with React components - Add comprehensive Host Styles panel showing all CSS variables grouped by category - Use React hooks (useApp, useHostStyles, useAutoResize) - Cleaner state management with useReducer for event log - Collapsible sections for better organization - CSS modules for scoped styling
This reverts commit 5d22d2d.
- serve script now runs main.ts instead of server.ts - Updated server name to 'Debug Server' - Fixed npx command in comment
- basic-host: Increase maxHeight from 600 to 6000px - debug-server: Add tools capability to enable oncalltool/onlisttools handlers
Event types now match callback names (ontoolinput, ontoolresult, etc.) so the Callback Status panel shows correct counts and payloads.
- Click on any event log row to expand/collapse - Arrow indicator rotates when expanded - Full JSON payload shown indented in pre block - Max height with scroll for large payloads
