🏗️ Architecture & Design Patterns

Serverless MCP Implementation

export class MyMCP extends McpAgent {
  server = new McpServer({
    name: "BlockchainHB Remote MCP Server",
    version: "1.0.0",
  });

  async init() {
    // Tool definitions with Zod validation
    this.server.tool(
      "scrape_linkedin_jobs",
      {
        jobTitle: z.string().describe("Job title to search for"),
        location: z.string().optional().describe("Location filter"),
        maxResults: z.number().min(1).max(100).default(10),
        // ... additional parameters
      },
      async (params) => {
        // Implementation with error handling
      }
    );
  }
}

Key Technical Implementations

1. Type-Safe API Design
  • Zod schema validation for all tool parameters
  • TypeScript interfaces for consistent data structures
  • Runtime type checking with descriptive error messages
2. Enterprise-Grade Error Handling
try {
  const response = await fetch(apiUrl, config);
  if (!response.ok) {
    throw new Error(`API failed: ${response.status} ${response.statusText}`);
  }
  return processResults(await response.json());
} catch (error) {
  return formatErrorResponse(error);
}
3. Optimized Data Processing
  • JSON streaming for large datasets
  • Memory-efficient result processing
  • Intelligent proxy rotation and retry logic

💡 Use Cases & Applications
