README
Cloudflare Worker 與 Docker 雙運行環境的 Model Context Protocol (MCP) 服務,內建 MCP Skills 知識庫 與 Redis 提問快取加速 機制。
Live Demo
🌟 核心特色
- 雙重運行環境 (Dual Runtime):
- ⛅ Cloudflare Workers:支援 Edge 邊緣全球部署,極速冷啟動與低延遲。
- 🐳 Docker & Node.js:提供
docker-compose.yml,一鍵啟動 MCP 服務與 Redis 容器。
- MCP Skills 知識庫:
- 完整介紹什麼是 MCP、什麼是 MCP Skill。
- 詳細比較 Tools (工具)、Resources (資源)、Prompts (提示詞) 的差異與組合模式。
- 提供各大客戶端 (Claude Desktop, Cursor, Zed, Cloudflare) 的配置指南。
- Redis 重複提問秒級直答 (Smart Caching):
- 當使用者提問時,系統會自動標準化問題並計算快取鍵。
- Cache HIT (命中):直接從 Redis 毫秒級回傳歷史快取結果,大幅節省 Token 與延遲。
- Cache MISS (未命中):檢索知識庫生成完整回答,自動快取至 Redis。
- 支援 Redis 斷線自動降級為記憶體快取 (Memory Fallback),確保高可用性。

🚀 快速開始
方式一:使用 Docker 啟動 (包含 Redis)
# 啟動 MCP 服務與 Redis 容器
docker compose up --build -d
# 查看運行日誌
docker compose logs -f
# 停止服務
docker compose down
服務啟動後:
- 服務首頁 / 儀表板:
http://localhost:3000/ - MCP 串流通訊端點:
http://localhost:3000/mcp或http://localhost:3000/sse - 健康檢查端點:
http://localhost:3000/health - REST 問答 API:
POST http://localhost:3000/api/ask
方式二:本機開發模式 (Node.js)
# 安裝依賴
npm install
# 執行單元測試 (驗證 MCP Tools & 快取機制)
npm test
# 啟動本機開發伺服器
npm run dev:node
方式三:部署至 Cloudflare Workers
1. 登入 Cloudflare
在終端機中執行:
npx wrangler login
瀏覽器會自動開啟進行 Cloudflare 帳號授權。
若使用 CI/CD 或 API Token 登入:
export CLOUDFLARE_API_TOKEN="你的 Cloudflare API Token" export CLOUDFLARE_ACCOUNT_ID="你的 Cloudflare Account ID"
2. 測試 Worker 本機模擬
npm run dev:worker
3. 部署到 Cloudflare 全球邊緣網路
npm run deploy
部署成功後,即可獲得專屬的 Worker 網址(例如 https://cf-mcp-playground.<your-subdomain>.workers.dev/mcp)。
🔌 在 AI 客戶端中使用
1. Claude Desktop 配置
編輯 claude_desktop_config.json:
- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"cf-mcp-remote": {
"url": "https://<your-worker>.workers.dev/sse"
},
"cf-mcp-docker": {
"command": "docker",
"args": ["exec", "-i", "cf-mcp-service", "node", "dist/node-server.js"]
}
}
}
2. Cursor 配置
在 Cursor 介面中進入 Settings -> Features -> MCP Servers -> Add New MCP Server:
- Name:
cf-mcp-service - Type:
sse - URL:
http://localhost:3000/sse(本地 Docker) 或https://<your-worker>.workers.dev/sse(遠端 Worker)
🧪 測試驗證範例
1. 測試 REST API 提問 (首次提問 - Cache MISS)
curl -X POST http://localhost:3000/api/ask \
-H "Content-Type: application/json" \
-d '{"question": "什麼是 MCP Skill?"}'
2. 測試相同提問 (重複提問 - Cache HIT ⚡)
curl -X POST http://localhost:3000/api/ask \
-H "Content-Type: application/json" \
-d '{"question": "什麼是 MCP Skill?"}'
3. 查看快取統計
curl http://localhost:3000/api/cache/stats
