### Serve via STDIO

**Note:** make sure to redirect oatpp logging to a different stream - ex.: to file by providing custom Logger.

```cpp
  /* Create MCP server */
  oatpp::mcp::Server server;

  /* Add prompts */
  server.addPrompt(std::make_shared());

  /* Add resource */
  server.addResource(std::make_shared());
  
  /* Add tools */
  server.addTool(std::make_shared());

  /* Run server */
  server.stdioListen(); 
```

### Serve via SSE

```cpp
  /* Create MCP server */
  oatpp::mcp::Server server;

  /* Add prompts */
  server.addPrompt(std::make_shared());

  /* Add resource */
  server.addResource(std::make_shared());
  
  /* Add tools */
  server.addTool(std::make_shared());

  /* Add SSE controller to your HTTP server router */
  router->addController(server.getSseController());
```
