Find working example in tests /test/oatpp-mcp/app/ServerTest.cpp

Serve via STDIO

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

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

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

  /* Add resource */
  server.addResource(std::make_shared<resource::File>());
  
  /* Add tools */
  server.addTool(std::make_shared<tools::Logger>());

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

Serve via SSE

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

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

  /* Add resource */
  server.addResource(std::make_shared<resource::File>());
  
  /* Add tools */
  server.addTool(std::make_shared<tools::Logger>());

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