# MCP Server 改進分析報告
## 執行摘要
本文檔分析了當前 MCP 伺服器的架構,並提出了全面的改進建議。這些改進按優先級和類別組織,旨在提升性能、可靠性、可擴展性和用戶體驗。
---
## 1. 性能優化 (Performance)
### 1.1 高優先級
#### 1.1.1 查詢結果緩存
**當前問題:** 每次搜索記憶都需要重新計算關鍵詞相關性和向量相似度
**影響:** 對於相似查詢重複計算,浪費 CPU 資源
**建議方案:**
```javascript
// src/utils/query-cache.js
export class QueryCache extends LRUCache {
constructor() {
super(50, 5 * 60 * 1000); // 緩存 50 個查詢,5分鐘過期
}
generateKey(keywords, conversationId, options) {
return `${conversationId}:${JSON.stringify(keywords)}:${JSON.stringify(options)}`;
}
}
```
**預期收益:** 減少 30-50% 的查詢計算時間
#### 1.1.2 關鍵詞提取批處理
**當前問題:** `extractKeywords` 每次處理單個文本,無法利用批處理優化
**影響:** 處理大量消息時效率低下
**建議方案:**
```javascript
// src/nlp/jieba.js
export function extractKeywordsBatch(texts, num) {
// 批量提取,減少函數調用開銷
return texts.map(text => extractKeywords(text, num));
}
```
#### 1.1.3 向量相似度計算優化
**當前問題:** 每次都重新計算向量的模(magnitude)
**影響:** 對於大向量(如 CLIP 的 512 維),計算開銷大
**建議方案:**
```javascript
// 在 modality 對象中預先計算並緩存向量模
function getModalityEmbedding(modality) {
// ...現有代碼
if (embedding && !modality._cachedMagnitude) {
modality._cachedMagnitude = Math.sqrt(
embedding.reduce((sum, val) => sum + val * val, 0)
);
}
return embedding;
}
```
**預期收益:** 向量比較速度提升 40-60%
### 1.2 中優先級
#### 1.2.1 內存池管理
**建議:** 為頻繁創建的對象實現對象池
```javascript
// src/utils/object-pool.js
export class KeywordPool {
constructor(initialSize = 1000) {
this.pool = [];
this.expand(initialSize);
}
acquire() {
return this.pool.pop() || { word: '', weight: 0 };
}
release(obj) {
obj.word = '';
obj.weight = 0;
this.pool.push(obj);
}
}
```
#### 1.2.2 懶加載長期記憶
**建議:** 僅在實際使用時才加載長期記憶觸發器
```javascript
async function getLongTermManager(conversationId) {
// 延遲加載策略
manager.lazyLoadTriggers = true;
}
```
#### 1.2.3 索引優化
**建議:** 為記憶添加索引結構
```javascript
// src/memory/index.js
export class MemoryIndex {
constructor() {
this.byKeyword = new Map(); // keyword -> memory IDs
this.byConversation = new Map(); // conversationId -> memory IDs
this.byTimeRange = new IntervalTree(); // 時間範圍索引
}
addMemory(memory, id) {
// 建立索引...
}
searchByKeyword(keyword) {
return this.byKeyword.get(keyword) || [];
}
}
```
**預期收益:** 搜索速度提升 3-10 倍
---
## 2. 可靠性與穩定性 (Reliability)
### 2.1 高優先級
#### 2.1.1 健康檢查端點
**當前問題:** 無法監控服務器健康狀態
**建議方案:**
```javascript
// src/health/index.js
export function createHealthCheck(managers) {
return {
async getHealth() {
return {
status: 'healthy',
uptime: process.uptime(),
memory: process.memoryUsage(),
caches: {
shortTerm: managers.shortTerm.size,
longTerm: managers.longTerm.size
},
timestamp: new Date().toISOString()
};
}
};
}
```
#### 2.1.2 斷路器模式
**當前問題:** 文件系統錯誤可能導致級聯故障
**建議方案:**
```javascript
// src/utils/circuit-breaker.js
export class CircuitBreaker {
constructor(threshold = 5, timeout = 60000) {
this.failures = 0;
this.threshold = threshold;
this.timeout = timeout;
this.state = 'CLOSED'; // CLOSED, OPEN, HALF_OPEN
}
async execute(fn) {
if (this.state === 'OPEN') {
throw new Error('Circuit breaker is OPEN');
}
try {
const result = await fn();
this.onSuccess();
return result;
} catch (error) {
this.onFailure();
throw error;
}
}
}
```
#### 2.1.3 請求超時處理
**當前問題:** 長時間運行的查詢可能阻塞服務器
**建議方案:**
```javascript
// src/utils/timeout.js
export async function withTimeout(promise, timeoutMs, errorMsg) {
return Promise.race([
promise,
new Promise((_, reject) =>
setTimeout(() => reject(new Error(errorMsg)), timeoutMs)
)
]);
}
// 使用示例
const result = await withTimeout(
manager.searchRelevantMemories(messages, conversationId),
5000,
'Search timeout after 5s'
);
```
### 2.2 中優先級
#### 2.2.1 數據完整性驗證
**建議:** 加載時驗證數據結構
```javascript
// src/memory/validator.js
import { z } from 'zod';
const ShortTermMemorySchema = z.object({
timestamp: z.string().datetime(),
text: z.string(),
keywords: z.array(z.object({
word: z.string(),
weight: z.number()
})),
score: z.number(),
conversation_id: z.string(),
modalities: z.array(z.any()).optional()
});
export function validateMemories(memories) {
return memories.filter((mem, idx) => {
try {
ShortTermMemorySchema.parse(mem);
return true;
} catch (error) {
console.error(`Invalid memory at index ${idx}:`, error);
return false;
}
});
}
```
#### 2.2.2 自動故障恢復
**建議:** 損壞文件自動備份並重建
```javascript
async function loadWithRecovery(filePath) {
try {
return await loadJsonFileIfExists(filePath, []);
} catch (error) {
console.error(`Corrupted file ${filePath}, attempting recovery...`);
await fs.copyFile(filePath, `${filePath}.corrupted.${Date.now()}`);
return [];
}
}
```
#### 2.2.3 寫入驗證
**建議:** 寫入後讀取驗證數據完整性
```javascript
async function saveWithVerification(filePath, data) {
await saveJsonFile(filePath, data, true);
const loaded = await loadJsonFileIfExists(filePath, null);
if (!loaded || JSON.stringify(loaded) !== JSON.stringify(data)) {
throw new Error('Data verification failed after write');
}
}
```

// 擴展記憶結構
{
...memory,
tags: ['important', 'personal', 'work'],
categories: ['preferences', 'facts']
}
```
#### 3.2.2 記憶優先級
**建議:** 為記憶添加優先級字段
```javascript
{
...memory,
priority: 'high' | 'medium' | 'low',
pinned: boolean

constructor(maxRequests = 100, windowMs = 60000) {
this.maxRequests = maxRequests;
this.windowMs = windowMs;
this.requests = new Map(); // conversationId -> [timestamps]
}
checkLimit(conversationId) {
const now = Date.now();
const requests = this.requests.get(conversationId) || [];
// 清理過期請求
const validRequests = requests.filter(ts => now - ts < this.windowMs);
if (validRequests.length >= this.maxRequests) {
throw new Error('Rate limit exceeded');
}
validRequests.push(now);
this.requests.set(conversationId, validRequests);
}
}
```
#### 4.1.2 輸入驗證與清理
**建議方案:**
```javascript
// src/security/input-validator.js
export function sanitizeInput(text) {
if (typeof text !== 'string') {
throw new Error('Input must be a string');
}
// 限制長度
if (text.length > 100000) {
throw new Error('Input too long (max 100KB)');
}
// 移除潛在危險字符
return text.replace(/[\x00-\x08\x0B\x0C\x0E-\x1F\x7F]/g, '');
}
export function validateConversationId(id) {
if (!/^[a-zA-Z0-9_-]{1,64}$/.test(id)) {

constructor(key) {
this.key = key;
}
encrypt(data) {
const iv = crypto.randomBytes(16);
const cipher = crypto.createCipheriv('aes-256-gcm', this.key, iv);
const encrypted = Buffer.concat([
cipher.update(JSON.stringify(data), 'utf8'),
cipher.final()
]);
const tag = cipher.getAuthTag();
return {
iv: iv.toString('hex'),
tag: tag.toString('hex'),
data: encrypted.toString('hex')
};
}
}
```
#### 4.2.2 訪問控制
**建議:** 實現基於角色的訪問控制

constructor() {
this.permissions = new Map();
}
checkPermission(conversationId, action) {
const perms = this.permissions.get(conversationId) || [];
if (!perms.includes(action)) {
throw new Error(`Permission denied: ${action}`);
}
}
}
```
---
## 5. 監控與可觀測性 (Monitoring)
### 5.1 高優先級
#### 5.1.1 結構化日誌
**建議方案:**

this.context = context;
}
log(level, message, meta = {}) {
const entry = {
timestamp: new Date().toISOString(),
level,
context: this.context,
message,
...meta
};
console.error(JSON.stringify(entry));
}
info(message, meta) { this.log('INFO', message, meta); }
warn(message, meta) { this.log('WARN', message, meta); }
error(message, meta) { this.log('ERROR', message, meta); }
}
```
#### 5.1.2 性能指標收集
**建議方案:**
```javascript
// src/monitoring/metrics.js
export class MetricsCollector {
constructor() {
this.metrics = {
requestCount: 0,
errorCount: 0,
requestDuration: [],
cacheHits: 0,
cacheMisses: 0
};
}
recordRequest(duration, success) {
this.metrics.requestCount++;
if (!success) this.metrics.errorCount++;
this.metrics.requestDuration.push(duration);
// 保持最近 1000 個請求的數據
if (this.metrics.requestDuration.length > 1000) {
this.metrics.requestDuration.shift();
}
}
getMetrics() {
const durations = this.metrics.requestDuration;
return {
...this.metrics,
avgDuration: durations.reduce((a, b) => a + b, 0) / durations.length,
p95Duration: this.percentile(durations, 0.95),
p99Duration: this.percentile(durations, 0.99),
errorRate: this.metrics.errorCount / this.metrics.requestCount
};
}
percentile(arr, p) {
const sorted = [...arr].sort((a, b) => a - b);
const index = Math.ceil(sorted.length * p) - 1;
return sorted[index];
}
}
```
### 5.2 中優先級
#### 5.2.1 追蹤與分析
**建議:** 為請求添加追蹤 ID
```javascript
// src/monitoring/tracing.js
export function generateTraceId() {
return `${Date.now()}-${Math.random().toString(36).substr(2, 9)}`;
}
// 在每個請求開始時
const traceId = generateTraceId();
logger.info('Request started', { traceId, toolName });
```
#### 5.2.2 告警系統
**建議:** 實現基於閾值的告警
```javascript
// src/monitoring/alerting.js
export class AlertManager {
constructor(thresholds) {
this.thresholds = thresholds;
this.alerts = [];
}
check(metrics) {
if (metrics.errorRate > this.thresholds.errorRate) {
this.alert({
severity: 'HIGH',
message: `Error rate ${metrics.errorRate} exceeds threshold ${this.thresholds.errorRate}`
});
}
if (metrics.p99Duration > this.thresholds.maxDuration) {
this.alert({
severity: 'MEDIUM',
message: `P99 duration ${metrics.p99Duration}ms exceeds threshold`
});
}
}
alert(alert) {
this.alerts.push({ ...alert, timestamp: new Date().toISOString() });
console.error('[ALERT]', alert);
}
}
```
---
## 6. 可擴展性 (Scalability)
### 6.1 中優先級
#### 6.1.1 分片存儲

export class ShardedStorage {
constructor(conversationId, shardCount = 4) {
this.conversationId = conversationId;
this.shardCount = shardCount;
}
getShardIndex(memoryId) {
// 基於記憶 ID 的哈希分片
let hash = 0;
for (let i = 0; i < memoryId.length; i++) {
hash = ((hash << 5) - hash) + memoryId.charCodeAt(i);
}
return Math.abs(hash) % this.shardCount;
}
async loadShard(shardIndex) {
const filePath = `${this.conversationDir}/shard-${shardIndex}.json`;
return await loadJsonFileIfExists(filePath, []);
}
}
```
#### 6.1.2 異步批處理
**建議:** 批量處理多個記憶操作
```javascript
// src/utils/batch-processor.js
export class BatchProcessor {
constructor(batchSize = 10, flushInterval = 1000) {
this.batchSize = batchSize;
this.flushInterval = flushInterval;
this.queue = [];
this.timer = null;
}
add(operation) {
this.queue.push(operation);
if (this.queue.length >= this.batchSize) {
this.flush();
} else if (!this.timer) {
this.timer = setTimeout(() => this.flush(), this.flushInterval);
}
}
async flush() {
if (this.timer) {
clearTimeout(this.timer);
this.timer = null;
}
const batch = this.queue.splice(0);
if (batch.length > 0) {
await this.processBatch(batch);
}
}
}
```
### 6.2 低優先級
#### 6.2.1 多進程支持
**建議:** 使用 Worker Threads 處理計算密集型任務
```javascript
// src/workers/keyword-worker.js
import { parentPort } from 'worker_threads';
parentPort.on('message', ({ texts, num }) => {
const results = texts.map(text => extractKeywords(text, num));
parentPort.postMessage(results);
});
```
---
## 7. 開發者體驗 (Developer Experience)
### 7.1 高優先級
#### 7.1.1 TypeScript 遷移
**建議:** 逐步遷移到 TypeScript
```typescript
// src/types.ts
export interface Memory {
timestamp: string;
text: string;
keywords: Keyword[];
score: number;
conversation_id: string;
modalities?: Modality[];
}
export interface Keyword {
word: string;
weight: number;
}
```
#### 7.1.2 單元測試
**建議:** 為核心功能添加測試
```javascript
// tests/short-term-memory.test.js
import { describe, it, expect } from 'vitest';
import { ShortTermMemoryManager } from '../src/memory/short-term.js';
describe('ShortTermMemoryManager', () => {
it('should calculate relevance correctly', async () => {
const manager = new ShortTermMemoryManager();
// 測試用例...
});
it('should handle time decay properly', async () => {
// 測試用例...
});
});
```
#### 7.1.3 API 文檔
**建議:** 使用 JSDoc 生成完整文檔
```javascript
/**
* 搜索相關記憶
* @param {Message[]} recentMessages - 最近的消息
* @param {string} conversationId - 當前對話 ID
* @param {SearchOptions} [options] - 搜索選項
* @param {number} [options.modalityVectorWeight=10] - 模態向量權重
* @param {Modality[]} [options.queryModalities] - 查詢模態
* @returns {Promise<SearchResult>} 搜索結果
* @throws {Error} 當 conversationId 無效時
*/
async searchRelevantMemories(recentMessages, conversationId, options = {}) {
// ...
}
```
### 7.2 中優先級
#### 7.2.1 配置文件支持
**建議:** 支持從配置文件加載設置
```javascript
// config/default.json
{
"memory": {
"shortTerm": {
"relevanceThreshold": 5,
"maxTopRelevant": 2,
"timeDecayFactor": 2e-9
},
"longTerm": {
"randomCount": 2
}
},
"cache": {
"maxSize": 100,
"maxAge": 1800000
},
"storage": {
"writeDelay": 1000,
"maxRetries": 3
}
}
```
#### 7.2.2 調試模式
**建議:** 添加詳細的調試日誌
```javascript
const DEBUG = process.env.DEBUG === 'true';
if (DEBUG) {
console.error('[DEBUG] Relevance calculation:', {
keywordScore,
timePenalty,
vectorScore,
total: relevanceScore
});
}
```
#### 7.2.3 性能分析工具
**建議:** 內置性能分析
```javascript
// src/utils/profiler.js
export class Profiler {
constructor() {
this.timings = new Map();
}
start(label) {
this.timings.set(label, performance.now());
}
end(label) {
const start = this.timings.get(label);
if (start) {
const duration = performance.now() - start;
console.error(`[Profile] ${label}: ${duration.toFixed(2)}ms`);
this.timings.delete(label);
}
}
}
```
---
## 8. 代碼質量 (Code Quality)
### 8.1 高優先級
#### 8.1.1 消除重複代碼
**當前問題:** short-term 和 long-term 中有重複的模態處理邏輯
**建議方案:**
```javascript
// src/memory/shared.js
export function normalizeMemoryModalities(memory) {
return normalizeModalities(memory.modalities ?? memory.attachments ?? []);
}
export function prepareMemoryForStorage(memory, type) {
const sanitized = { ...memory };
stripEphemeralFields(sanitized);
const modalities = normalizeMemoryModalities(memory);
sanitized.modalities = deduplicateImageModalities(modalities);
delete sanitized.attachments;
if (type === 'short-term') {
return prepareShortTermSpecific(sanitized);
} else {
return prepareLongTermSpecific(sanitized);
}
}
```
#### 8.1.2 錯誤處理標準化
**建議方案:**
```javascript
// src/utils/errors.js
export class MemoryError extends Error {
constructor(message, code, details = {}) {
super(message);
this.name = 'MemoryError';
this.code = code;
this.details = details;
}
}
export class ValidationError extends MemoryError {
constructor(message, details) {
super(message, 'VALIDATION_ERROR', details);
}
}
export class StorageError extends MemoryError {
constructor(message, details) {
super(message, 'STORAGE_ERROR', details);
}
}
```
#### 8.1.3 常量集中管理
**建議方案:**
```javascript
// src/config/constants.js
export const MEMORY_CONSTANTS = {
SHORT_TERM: {
RELEVANCE_THRESHOLD: 5,
SCORE_INCREMENT_TOP: 5,
SCORE_INCREMENT_NEXT: 2,
MAX_TOP_RELEVANT: 2,
MAX_NEXT_RELEVANT: 1,
MAX_RANDOM_FLASHBACK: 2,
CLEANUP_INTERVAL_MS: 24 * 60 * 60 * 1000,
MEMORY_TTL_MS: 365 * 24 * 60 * 60 * 1000
},
LONG_TERM: {
RANDOM_COUNT: 2
},
CACHE: {
MAX_SIZE: 100,
MAX_AGE_MS: 30 * 60 * 1000
}
};
```
### 8.2 中優先級
#### 8.2.1 函數分解
**建議:** 將大函數拆分為小函數
```javascript
// src/memory/short-term.js - 重構 searchRelevantMemories
async searchRelevantMemories(recentMessages, conversationId, options = {}) {
const context = await this.prepareSearchContext(recentMessages, options);
const scoredMemories = this.scoreAllMemories(context);
const filtered = this.filterByRelevance(scoredMemories);
const selected = this.selectMemories(filtered, conversationId, context.currentTimeStamp);
this.updateMemoryScores(selected);
return this.formatSearchResults(selected);
}
```
#### 8.2.2 參數對象模式
**建議:** 使用對象參數替代多個參數
```javascript
// 之前
calculateRelevance(memory, keywords, timestamp, options)
// 之後
calculateRelevance({
memory,
keywords,
timestamp,
modalityVectorWeight,
queryModalities
})
```
