+## About the Weather MCP Server
+
+**Location**: \`samples/tools/weather-mcp-server.mjs\`
+**Transport**: HTTP (runs on port 3001)
+**Tools**:
+- \`get_current_weather\` - Get current weather for a city
+- \`get_weather_forecast\` - Get 3-day weather forecast  
+- \`compare_weather\` - Compare weather between two cities
+
+**Available Cities**: Paris, London, New York, Tokyo, Sydney, Berlin, Moscow, Mumbai, Cairo, Vancouver
+
+**To start the server**:
+\`\`\`bash
+node samples/tools/weather-mcp-server.mjs
+\`\`\`
+
+## MCP Configuration Types
 
 **Note**: Since our weather server uses HTTP transport, we need to use the programmatic approach instead.
 The mcpServers configuration is designed for process-based MCP servers that can be launched via command line.
 
-For HTTP-based MCP servers, see the weather-mcp-http.genai.mts example.
+For HTTP-based MCP servers like our weather example, see \`weather-mcp-http.genai.mts\`.
 
 Cities to check: ${cities.join(", ")}
 
 To use process-based MCP servers, you would configure them in the mcpServers section:
 \`\`\`typescript
 mcpServers: {
     fetch: {
-        command: "npx",
+        command: "npx", 
         args: ["@modelcontextprotocol/server-fetch"]
     }
 }
