+### Testing NLWeb Features
 
-Once the core library is implemented, you'll be able to test:
+The demo application at `http://localhost:5037` provides comprehensive testing of all NLWeb protocol features:
 
-**Interactive Demo (`/nlweb`):**
+**Interactive Demo Pages:**
 
-- Natural language queries like "What are the latest updates?" or "Find documentation about API endpoints"
-- **List Mode**: See ranked search results
-- **Summarize Mode**: Get AI-generated summaries with supporting results
+- **Home Page (`/`)**: Project overview and navigation to demo features
+- **NLWeb Demo (`/nlweb`)**: Advanced query interface with tabbed sections:
+  - **Query Tab**: Interactive form with all NLWeb parameters (query, mode, site, etc.)
+  - **Streaming Tab**: Real-time streaming response demonstration
+  - **API Test Tab**: Raw HTTP request/response testing
+- **API Test (`/api-test`)**: Comprehensive API testing interface with request configuration
+- **MCP Demo (`/mcp-demo`)**: Model Context Protocol demonstration with tools and prompts
+
+**Query Modes Supported:**
+
+- **List Mode**: Returns ranked search results with relevance scoring
+- **Summarize Mode**: AI-generated summaries with supporting results  
 - **Generate Mode**: Full RAG responses with context-aware answers
-- Real-time streaming responses for immediate feedback
+- **Streaming**: Real-time response delivery with Server-Sent Events
 
 **API Testing:**
 
 - Direct HTTP calls to `/ask` endpoint with various parameters
-- MCP protocol testing via `/mcp` endpoint
-- OpenAPI specification for automated testing and integration
+- MCP protocol testing via `/mcp` endpoint with tool and prompt support
+- OpenAPI specification available at `/openapi/v1.json`
+- Comprehensive manual testing guides in `/doc/manual-testing-guide.md`
 
 **Example API Usage:**
 
 ```bash
 # List mode query
 curl -X GET "http://localhost:5037/ask?query=find+recent+updates&mode=list"
 
-# POST request equivalent
+# POST request with full parameters
 curl -X POST "http://localhost:5037/ask" \
   -H "Content-Type: application/json" \
-  -d '{"query": "find recent updates", "mode": "list"}'
+  -d '{"query": "find recent updates", "mode": "list", "site": "docs", "streaming": false}'
 
 # Streaming summarize query  
 curl -X POST "http://localhost:5037/ask" \
   -H "Content-Type: application/json" \
   -d '{"query": "what are the main features?", "mode": "summarize", "streaming": true}'
+
+# MCP tool listing
+curl -X POST "http://localhost:5037/mcp" \
+  -H "Content-Type: application/json" \
