Anthropic Streaming Chat with MCP\n\nA mobile-optimized single page chat application that uses the Anthropic Messages API with **real-time streaming** and MCP (Model Context Protocol) server support.\n\nSource: https://www.val.town/x/c15r/Chat \n\nLive server: https://c15r--7471cb243cdd11f08caa9e149126039e.web.val.run\n\nBundles Contextual MCP server by default: https://c15r--1564b217248f4a97a4d37bfe82cb8b19.web.val.run/mcp\n\n\n\n## Features\n\n- **🚀 Real-time streaming responses** - See Claude's responses appear word-by-word as they're generated\n- **⏹️ Stream control** - Stop streaming at any time with the stop button\n- Full-screen mobile-optimized chat interface\n- Direct client-side Anthropic API integration with server-side streaming proxy\n- **Model selection** - Choose between different Claude models (3.5 Sonnet, 3.5 Haiku, 3 Opus, etc.) without clearing chat history\n- Configurable MCP servers with localStorage persistence\n- **🔍 Automatic MCP Server Status Checking** - Servers are automatically tested at startup with progressive disclosure of status, tools, prompts, and error details\n- **📊 MCP Status Dashboard** - Expandable status panel showing server connectivity, available prompts, available tools, and error details\n- **Clean footer layout** with text-based settings and clear chat links positioned alongside status text\n- **Enhanced MCP response handling** with collapsible sections for complex tool use and results\n- **Persistent chat history** - messages are saved to localStorage and restored on page load\n- **Structured display of MCP tool calls and results** to prevent truncation\n- **Frontend MCP server testing** - test button for each MCP server with visual status indicators (✅/❌)\n- **Frontend MCP prompt fetching** - prompts are fetched directly from MCP servers with caching support\n- **Frontend MCP tool fetching** - tools are fetched directly from MCP servers with caching support\n\n## Streaming Implementation\n\nThis app implements Anthropic's official streaming guide using:\n- Server-Sent Events (SSE) for real-time communication\n- Proper event parsing (`message_start`, `content_block_delta`, `message_stop`, etc.)\n- Content block reassembly for text, tool use, and thinking responses\n- Error handling and keep-alive support\n- Token usage tracking\n- Support for all delta types (text, JSON, thinking)\n\n## Project Structure\n\n```\n├── backend/\n│ └── index.ts # Hono server with static file serving\n├── frontend/\n│ ├── index.html # Main HTML template\n│ ├──

localStorage:\n- `anthropic_api_key`: Your Anthropic API key\n- `selected_model`: The chosen Claude model (defaults to claude-3-5-sonnet-20241022)\n- `mcp_servers`: Array of configured MCP servers\n- `chat_messages`: Complete chat history (persists between page loads)\n\n## API Endpoints\n\n- `GET /` - Main application (serves frontend)\n- `GET /frontend/*` - Frontend static files\n- `GET /shared/*` - Shared utility files\n\n**Note**: MCP server testing and prompt fetching are now handled directly on the frontend for improved performance and reduced server load.\n\n## Usage\n\n1. Open the app at the provided URL\n2. Click \"Settings\" in the footer to configure your Anthropic API key and select your preferred Claude model\n3. Add/remove/toggle MCP servers as needed\n4. Use the \"Test\" button next to each MCP server to verify connectivity (shows ✅ for success, ❌ for errors)\n5. Start chatting with Claude and watch responses stream in real-time!\n6. Use the stop button (⏹️) to interrupt streaming at any time\n6. Switch models anytime in settings without losing your chat history\n7. Your chat history and settings will be automatically saved and restored when you return\n\n## Default MCP Server\n\nThe app comes pre-configured with the Val Town MCP server:\n- **Name**: Val Town MCP\n- **URL**: `https://c15r--81c497c63c0a11f081e29e149126039e.web.val.run/mcp`\n- **Status**: Enabled by default (you'll need to add your authorization token)\n\n## Features in Detail\n\n- **Mobile-First Design**: Optimized for mobile devices with touch-friendly controls\n- **Real-time Streaming**: Watch Claude's responses appear word-by-word as they're generated\n- **Stream Control**: Stop streaming responses at any time with the stop button\n- **MCP Integration**: Support for multiple Model Context Protocol servers\n- **Enhanced MCP Display**: Collapsible sections for tool calls and results with proper JSON formatting\n- **Unobtrusive Footer Controls**: Settings (⚙️) and clear chat (🗑️) buttons positioned in the footer alongside the input\n- **Persistent Chat History**: All messages automatically saved to localStorage and restored on page load\n- **Persistent Settings**: All configuration stored in browser localStorage\n- **Auto-scroll**: Messages automatically scroll to bottom during streaming\n- **Auto-resize**: Input field grows with content\n- **Error Handling**: Clear error messages for API issues with stream recovery\n- **Loading States**: Visual feedback during
