/* 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

/* 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());
