`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- `auto_execute_next_steps`: Global setting for NextSteps auto-execution (defaults to true)\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. Configure NextSteps auto-execution in settings (enabled by default)\n6. Start chatting with Claude and watch responses stream in real-time!\n7. Use the stop button (⏹️) to interrupt streaming at any time\n8. Switch models anytime in settings without losing your chat history\n9. Your chat history and settings will be automatically saved and restored when you return\n10. When MCP tools return NextSteps proposals, they'll appear as interactive pills that can auto-execute or require manual selection\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- **NextSteps Auto-Execution**: MCP tools can propose follow-up actions that execute automatically after a countdown or require manual selection. See [NextSteps-README.md](./NextSteps-README.md) for implementation details.\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 API calls and streaming\n- **Structured Responses**: MCP tool use and results are displayed in organized, collapsible sections\n- **Clean Interface**: Maximized chat area with no header, footer contains all controls\n- **Streaming Animations**: Visual cursor and highlighting for active streaming responses","label",[136],"f23a9f50-4b00-11f0-affa-76b3cceeab13","NextSteps-README.md","f23aa00e-4b00-11f0-affa-76b3cceeab13",709,["D",1750112788444],"# NextSteps Feature Documentation\n\n## Overview\n\nNextSteps is a dynamic interaction feature that allows MCP (Model Context Protocol) servers to propose follow-up actions to users after tool execution. These proposals can be automatically executed after a countdown or manually selected by the user, enabling fluid conversational workflows and guided user experiences.\n\n## User Experience\n\n### Visual Design\n- **Inline Pills**: NextSteps appear as pill-shaped buttons within assistant messages\n- **Progress Indicators**: Visual progress bars show countdown timers (auto) or priority levels (manual)\n- **Countdown Display**: Numeric countdown badge shows remaining seconds for auto-execution\n- **Cancellation**: User interaction (hover, click, typing) cancels auto-execution\n\n### Interaction Modes\n1. **Auto Execution**: Proposals with `type: \"auto\"` automatically execute after countdown\n2. **Manual Selection**: Proposals with `type: \"manual\"` require user click to execute\n3. **Priority Display**: Manual proposals show static progress bars indicating relative priority\n\n### Global Settings\n- **Auto-Execution Toggle**: Users can globally enable/disable auto-execution in settings\n- **Per-Result Override**: Individual NextSteps can specify \"auto\" or \"manual\" regardless of global setting\n- **Cancellation**: Any user interaction cancels pending auto-execution\n\n## MCP Server Implementation Spec\n\n### Response Format\n\nMCP servers should return NextSteps data in their tool result's `output.nextSteps` field:\n\n```json\n{\n \"content\": [\n {\n \"type\": \"text\", \n \"text\": \"{\\\"output\\\": {\\\"nextSteps\\\": {...}}}\"\n }\n ]\n}\n```\n\n### NextSteps Schema\n\n```typescript\ninterface NextStepsOutput {\n nextSteps: {\n type: \"auto\" | \"manual\";

Log a warning to console\n2. Fall back to displaying the raw tool result\n3. Continue normal operation\n\nServers should validate their NextSteps output to ensure:\n- Required fields are present\n- IDs are unique within the proposal set\n- Countdown values are reasonable (1-60 seconds)\n- Priority values are within 0-100 range\n\n### Integration with Existing Tools\n\nNextSteps works alongside existing MCP tool capabilities:\n- **HTML Output**: Can be combined with `output.html` for rich displays\n- **File Operations**: Suggest follow-up actions after file creation/modification\n- **API Calls**: Propose next API operations or data processing steps\n- **Database Operations**: Suggest queries, updates, or analysis steps\n\n### Client Implementation Notes\n\nThe NextSteps feature is implemented in the chat client with:\n- Global auto-execution setting in user preferences\n- Per-message override capability\n- User interaction cancellation (hover, click, typing)\n- Visual progress indicators and countdown timers\n- Persistent storage of user preferences\n- Mobile-responsive pill-based UI\n\n### Future Enhancements\n\nPlanned future capabilities:\n- **Action Types**: Support for file downloads, API calls, tool execution\n- **Conditional Logic**: Proposals based on user context or previous actions\n- **Scheduling**: Delayed execution beyond immediate countdown\n- **Branching**: Multiple workflow paths with decision points\n- **Templates**: Reusable NextSteps patterns for common workflows\n\n## Testing Your Implementation\n\n### Manual Testing\n1. Create a tool that returns NextSteps in the specified format\n2. Test both auto and manual execution modes\n3. Verify countdown timers work correctly\n4. Test user cancellation by interacting during countdown\n5. Verify priority display for manual proposals\n\n### Example Test Tool\n```python\ndef create_test_nextsteps():\n return {\n \"output\": {\n \"nextSteps\": {\n \"type\": \"auto\",\n \"countdown\": 5,\n \"proposals\": [\n {\n \"id\": \"test_action\",\n \"title\": \"Test Action\",\n \"description\": \"This is a test NextSteps proposal\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"NextSteps test completed successfully!\"\n }\n }\n ]\n }\n }\n }\n```\n\n### Validation Checklist\n- [ ] NextSteps object structure matches schema\n- [ ] All required fields are present\n- [ ] Proposal IDs are unique\n- [ ] Countdown values are reasonable (1-60s)\n- [ ] Priority values are 0-100\n- [ ] Action content is meaningful\n- [ ] Titles are concise and descriptive\n- [ ] Descriptions provide helpful context\n\n## Support and Feedback\n\nFor questions about implementing NextSteps in your MCP server:\n- Review the examples in this documentation\n- Test with the provided validation checklist\n- Check browser console for any parsing errors\n- Ensure JSON structure exactly matches the schema\n\nThe NextSteps feature enhances user experience by providing intelligent workflow guidance while maintaining user control and preventing unwanted automatic actions.",[147],"2bef5d30-4b01-11f0-95ed-76b3cceeab13","NextSteps-Examples.md","2bef5dee-4b01-11f0-95ed-76b3cceeab13",714,["D",1750112885258],"# NextSteps Implementation Examples\n\nThis document provides practical examples of how to implement NextSteps in your MCP server tools.\n\n## Example 1: File Analysis Tool with Auto-Continue\n\n```python\ndef analyze_file(file_path):\n \"\"\"Analyze a file and suggest next steps\"\"\"\n \n #
