## 從實驗性協議到行業標準：MCP 的演進之路

Model Context Protocol (MCP) 自 2024 年底由 Anthropic 發布以來，已經從一個實驗性的整合協議快速演進為 AI 生態系統的核心基礎設施。根據 Anthropic 官方發布的 **2025H1 路線圖**，MCP 正朝著成為「AI 領域的 HTTP 協議」這一宏大目標穩步前進。

## MCP 官方路線圖解析

### 第一階段：遠程 MCP 支援 (2025 Q1-Q2)

**核心目標：突破本地部署限制**

```
當前狀態：主要為本地 STDIO 連接
目標狀態：支援企業級遠程部署
關鍵里程碑：
├─ 身份認證與授權機制
├─ 服務發現與註冊
└─ 無狀態操作支援
```

#### 身份認證革命

**OAuth 2.0 + 可插拔認證架構**

```python
class MCPAuthenticationFramework:
    def __init__(self):
        self.auth_providers = {
            'oauth2': OAuth2Provider(),
            'did_wba': DIDWebAuthnProvider(),  # W3C DID 標準
            'api_key': APIKeyProvider(),
            'mutual_tls': MutualTLSProvider()
        }
        
    async def authenticate_connection(self, auth_request: dict):
        """多方式身份認證"""
        
        auth_method = auth_request.get('method', 'oauth2')
        provider = self.auth_providers.get(auth_method)
        
        if not provider:
            raise UnsupportedAuthMethodException(f"未支援的認證方式: {auth_method}")
            
        # 執行認證流程
        auth_result = await provider.authenticate({
            'credentials': auth_request['credentials'],
            'client_info': auth_request['client_info'],
            'requested_scopes': auth_request.get('scopes', [])
        })
        
        if auth_result['authenticated']:
            # 生成 MCP 訪問憑證
            mcp_token = await self.generate_mcp_access_token({
                'identity': auth_result['identity'],
                'scopes': auth_result['granted_scopes'],
                'expiry': datetime.now() + timedelta(hours=24)
            })
            
            return {
                'status': 'authenticated',
                'access_token': mcp_token,
                'token_type': 'bearer',
                'expires_in': 86400,
                'scope': ' '.join(auth_result['granted_scopes'])
            }
        else:
            raise AuthenticationFailedException(auth_result['error_message'])
```

#### 服務發現機制

**類似 OpenAI GPTs 的 MCP 服務市場**

```python
class MCPServiceRegistry:
    def __init__(self):
        self.registry_endpoint = "https://registry.modelcontextprotocol.org"
        self.service_cache = TTLCache(maxsize=1000, ttl=300)
        
    async def discover_services(self, discovery_criteria: dict):
        """智能服務發現"""
        
        # 1. 建構查詢參數
        query_params = {
            'capabilities': discovery_criteria.get('required_capabilities', []),
            'domains': discovery_criteria.get('domains', []),
            'quality_threshold': discovery_criteria.get('min_quality', 0.8),
            'availability_zone': discovery_criteria.get('preferred_region', 'any'),
            'pricing_model': discovery_criteria.get('pricing', 'any')
        }
        
        # 2. 查詢註冊中心
        search_results = await self.query_registry(query_params)
        
        # 3. 服務品質評估
        qualified_services = []
        for service in search_results:
            quality_metrics = await self.evaluate_service_quality({
                'service_metadata': service,
                'historical_performance': await self.get_service_history(service['id']),
                'user_reviews': await self.get_service_reviews(service['id'])
            })
            
            if quality_metrics['overall_score'] >= query_params['quality_threshold']:
                qualified_services.append({
                    'service': service,
                    'quality_score': quality_metrics['overall_score'],
                    'quality_breakdown': quality_metrics['breakdown'],
                    'estimated_cost': await self.estimate_usage_cost(service, discovery_criteria)
                })
                
        # 4. 排序並返回推薦清單
        return sorted(qualified_services, 
                     key=lambda x: x['quality_score'], 
                     reverse=True)
```

        }
        
        container = await self.container_runtime.create_container(container_config)
        
        # 3. 啟動監控
        monitoring_session = await self.resource_monitor.start_monitoring({
            'container_id': container.id,
            'resource_limits': container_config['resource_limits'],

```

### 第三階段：Agent 支援 (2025 Q3-Q4)

**目標：多層 Agent 系統、互動式工作流程、串流結果**

#### 分層 Agent 架構

```python

### 第四階段：生態系統標準化 (2025 Q4-2026)

**目標：開放治理、標準化機構合作、社群驱動發展**

#### 開放治理架構

## 技術演進的三大驅動力

### 1. 企業需求驅動 (Demand-Pull Innovation)

**企業痛點推動協議演進：**
