Implementation Reference

• src/tools.ts:161-174 (handler)

  Core handler function implementing the get_server_info tool logic. Returns a ServerInfo object containing server name, version, description, and list of available tools.

  export function getServerInfo(): ServerInfo {
    return {
      name: "my-first-mcp",
      version: "1.0.0",
      description: "MCP 서버 개발 튜토리얼 - 첫 번째 MCP 서버",
      tools: [
        "get_current_time - 현재 시간 조회",
        "calculate - 사칙연산 계산기",
        "get_random_number - 랜덤 숫자 생성",
        "reverse_string - 문자열 뒤집기",
        "get_server_info - 서버 정보 조회",
      ],
    };
  }

• src/tools.ts:154-159 (schema)

  Type definition (schema) for the ServerInfo output returned by the get_server_info handler.

  export interface ServerInfo {
    name: string;
    version: string;
    description: string;
    tools: string[];
  }

• src/index.ts:244-272 (registration)

  Registration of the get_server_info tool in the MCP server. Includes empty input schema ({}), description, and thin wrapper handler that formats the output from getServerInfo() as MCP text content response.

  server.tool(
    "get_server_info",
    "이 MCP 서버의 정보와 사용 가능한 Tool 목록을 반환합니다.",
    {},
    async () => {
      const info = getServerInfo();
  
      const infoText = `
  === ${info.name} 서버 정보 ===
  
  버전: ${info.version}
  설명: ${info.description}
  
  사용 가능한 Tool:
  ${info.tools.map((t, i) => `${i + 1}. ${t}`).join("\n")}
