MCP API Server

- MCP protocol integration with tool and resource support
- Dynamic API tool registration via OpenAPI specification
- Automatic parameter conversion from OpenAPI to MCP input schema
- Security filtering to expose only safe API parameters
- Built-in caching for API specification data
- Error handling for stable tool invocation

Install Node.js 18+, npm 9+, and TypeScript 5.0+. Clone the repository, run npm install, then npm run build. Configure the server by setting the required environment variables (e.g., BASE_URL, CLIENT_ID, CLIENT_SECRET, ALLOWED_APIS) in the mcpServers section of your MCP client configuration. The server automatically discovers and registers API endpoints based on an OpenAPI specification and the ALLOWED_APIS filter list.

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) }] };

    }

  });
