Implementation Reference
- src/server.js:218-253 (handler)Handler for flip_coin tool in stdio MCP server switch statement: validates input count, performs multiple coin flips using Math.random() < 0.5 for '正面'(heads) or '反面'(tails), tallies results, formats output text.
case 'flip_coin': { // 抛硬币工具：模拟抛硬币 const { count = 1 } = args; // 参数验证 if (count < 1) { throw new Error('抛硬币次数至少为1'); } // 执行抛硬币逻辑 const results = []; let heads = 0; // 正面次数 let tails = 0; // 反面次数 for (let i = 0; i < count; i++) { // 50% 概率生成正面或反面 const result = Math.random() < 0.5 ? '正面' : '反面'; results.push(result); if (result === '正面') heads++; else tails++; } // 根据抛硬币次数格式化输出 const resultText = count === 1 ? `🪙 抛硬币结果：${results[0]}` : `🪙 抛硬币结果：${results.join(', ')}\n📊 统计：正面 ${heads} 次，反面 ${tails} 次`; return { content: [ { type: 'text', text: resultText, }, ], }; } - src/server-http.js:143-173 (handler)Handler for flip_coin tool in HTTP server's handleToolCall function: identical implementation to stdio server version.
