About MCP API Server

What is MCP API Server: Seamless API Integration & Enterprise Scalability?

MCP API Server is a robust enterprise-grade microservices framework designed to simplify API integration and scaling. Built with Node.js 18+ and TypeScript 5.0+, it leverages the MCP protocol to dynamically expose API endpoints as modular tools. The server automatically discovers and registers APIs via OpenAPI specifications, enabling secure, scalable access to backend systems without manual configuration. Key to its design are enterprise-ready features like parameter filtering, error resilience, and performance-optimized caching.

How to Use MCP API Server: Seamless API Integration & Enterprise Scalability?

Get started by cloning the repository and installing dependencies. Configure allowed APIs through the MCP server JSON schema, specifying endpoint white lists and security parameters. The server auto-generates tool definitions from your OpenAPI specs, handling HTTP method routing transparently. For production, build the TypeScript codebase and run using node. Advanced users can customize tool behavior by modifying the apiEndpoints.ts logic or extending the tools/index.ts registration handlers.

MCP API Server Features

Key Features of MCP API Server: Seamless API Integration & Enterprise Scalability?

  • Auto Discovery: Instantly surface new APIs via OpenAPI v3 specs without code changes
  • Security Filters: Smart parameter masking and access controls prevent exposure of internal fields
  • Dynamic Tooling: MCP protocol support enables real-time API evolution in connected ecosystems
  • Enterprise-Grade: Built-in rate limiting, TLS validation, and tenant isolation through TENANT_ID
  • Developer Friendly: TypeScript type safety combined with auto-generated tool schemas

Use Cases of MCP API Server: Seamless API Integration & Enterprise Scalability?

Common applications include:

  • Centralized API gateway for multi-tenant SaaS platforms
  • Backend-for-Frontend patterns in decoupled architecture
  • API as a service integration in enterprise toolchains
  • Legacy system exposure without modifying existing APIs
  • Dynamic API catalog for AI/automation tool consumption

MCP API Server FAQ

FAQ from MCP API Server: Seamless API Integration & Enterprise Scalability?

Q: How does MCP handle API versioning?
A: Versioning is managed via OpenAPI spec URLs - simply update the spec path in config to switch versions

Q: Can I customize error responses?
A: Yes, override the default error handler in src/error-handler.ts to implement organization-specific logging

Q: What's the performance overhead?
A: Benchmark shows <1ms overhead per request thanks to in-memory API spec caching and HTTP method routing optimizations

Q: Does it support gRPC?
A: Current implementation focuses on REST APIs, but gRPC support is planned for v2.0 milestone

动态API工具系统

MCP-Server 实现了基于 OpenAPI 规范的动态工具发现和注册机制,无需手动配置即可自动生成 MCP 工具。

apiEndpoints.ts 功能说明

// 从OpenAPI规范自动获取API端点信息
const openApiData = await fetchOpenApiData();

// 根据配置的允许列表过滤API
const API_ENDPOINTS = Object.entries(openApiData.paths)
    .filter(([path]) => config.ALLOWED_APIS.includes(path))
    .map(([path, methods]) => {
        // 转换为标准工具格式
        return Object.entries(methods).map(([method, details]) => ({
            name: details.operationId,
            description: details.summary,
            inputSchema: details.parameters ? {
                type: 'object',
                properties: Object.fromEntries(details.parameters
                    .filter(isExposableParameter)
                    .map(transformParameterToProperty)
                )
            } : {},
            path: path,
            method: method.toUpperCase()
        }));
    }).flat();

tools/index.ts 工具注册机制

export function registerTools(server: Server) {
  // 注册可用工具列表
  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: tools,
  }));

  // 处理工具调用请求
  server.setRequestHandler(CallToolRequestSchema, async (request) => {
    const endpoint = apiMap[request.params.name];
    
    // 根据HTTP方法类型动态处理请求
    if(endpoint.method === 'GET') {
      const response = await apiClient.get(endpoint.path, { params: request.params.arguments });
      return { content: [{ type: 'text', text: JSON.stringify(response.data, null, 2) }] };
    } else if(endpoint.method === 'POST') {
      const response = await apiClient.post(endpoint.path, request.params.arguments);
      return { content: [{ type: 'text', text: JSON.stringify(response.data, null, 2) }] };
    } else if(endpoint.method === 'PUT') {
      const response = await apiClient.put(endpoint.path, request.params.arguments);
      return { content: [{ type: 'text', text: JSON.stringify(response.data, null, 2) }] };
    }
  });
}
