 ## Running the Container
 
-### Basic Usage
+### HTTP Mode (Default)
 
-Run the container with your API key:
+The Docker container runs in HTTP mode by default, making it accessible via HTTP requests:
 
 ```bash
-docker run --rm -e PERPLEXITY_API_KEY=your_key_here perplexity-mcp-server

 ```
 
+The server will be accessible at `http://localhost:8080/mcp`
+
 ### With Custom Timeout
 
 Set a custom timeout for requests (default is 5 minutes):

 ## Integration with MCP Clients
 
-When using Docker with MCP clients, configure them to run the Docker container. For example, in Cursor/VS Code's `mcp.json`:
+When using the HTTP Docker server, configure your MCP client to connect to the HTTP endpoint:
 
 ```json
 {
   "mcpServers": {
     "perplexity": {
-      "command": "docker",
-      "args": [
-        "run",
-        "--rm",
-        "-i",
-        "-e", "PERPLEXITY_API_KEY=your_key_here",
-        "perplexity-mcp-server"
-      ]
+      "url": "http://localhost:8080/mcp"
     }
   }
 }
 ```
 
-> **Note**: Docker-based MCP server configuration may have limitations compared to direct `npx` usage. For most use cases, the `npx` method documented in the main README is recommended.
+## STDIO Mode (Local Development)
+
+For local development with STDIO transport, you can still run the server locally without Docker:
+
+```bash
+npm install
+npm run build
+PERPLEXITY_API_KEY=your_key_here npm start
+```
+
+> **Note**: The Docker image is optimized for HTTP mode deployment. For local STDIO usage, the `npx` method documented in the main README is recommended.

 > The server checks proxy settings in this order: `PERPLEXITY_PROXY` → `HTTPS_PROXY` → `HTTP_PROXY`. If none are set, it connects directly to the internet.

+### HTTP Server Deployment
+
+For cloud or shared deployments, you can run the server in HTTP mode:
+
+#### Environment Variables
+
+The HTTP server supports these configuration options:
+
+- **`PORT`** - HTTP server port (default: `8080`)
+- **`BIND_ADDRESS`** - Network interface to bind to (default: `127.0.0.1` for local, use `0.0.0.0` for hosted)
+- **`ALLOWED_ORIGINS`** - Comma-separated list of allowed CORS origins (default: `http://localhost:3000,http://127.0.0.1:3000`, use `*` for public service)
+- **`PERPLEXITY_API_KEY`** - Your Perplexity API key (required)
+
+#### Using Docker
+
+```bash
+docker build -t perplexity-mcp-server .
+docker run -p 8080:8080 -e PERPLEXITY_API_KEY=your_key_here perplexity-mcp-server
+```
+
+The server will be accessible at `http://localhost:8080/mcp`
+
+#### Using Node.js Directly
+
+```bash
+npm install
+npm run build
+npm run start:http
+```
+
+Connect your MCP client to: `http://localhost:8080/mcp`
+
+
 ## Troubleshooting
 
 - **API Key Issues**: Ensure `PERPLEXITY_API_KEY` is set correctly
