+### Browser Context Transport
+
+For in-browser applications, use the BrowserContextTransport to enable communication between browser contexts (same window, iframes, or web workers):
+
+```typescript
+import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
+import { BrowserContextTransport } from "@modelcontextprotocol/sdk/browser-context-transport.js";
+
+// Create paired transports
+const [clientTransport, serverTransport] = BrowserContextTransport.createChannelPair();
+
+// Set up server
+const server = new McpServer({
+  name: "browser-server",
+  version: "1.0.0"
+});
+
+// Connect server to its transport
+await server.connect(serverTransport);
+
+// The clientTransport can be used with an MCP client
+```
+
 ### Testing and Debugging
 
 To test your server, you can use the [MCP Inspector](https://github.com/modelcontextprotocol/inspector). See its README for more information.
