Generated Code Patterns

Server Setup (src/server.ts)

import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
import { registerTools } from './tools';
import { registerResources } from './resources';

export async function createServer() {
  const server = new McpServer({
    name: '<serverName>',
    version: '1.0.0',
  });

  // Register capabilities
  registerTools(server);
  registerResources(server);

  return server;
}

export async function startServer() {
  const server = await createServer();
  const transport = new StdioServerTransport();

  await server.connect(transport);

  console.error('[MCP] Server started on stdio');
}

Tool Handler (src/tools/.ts)

import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';
import { z } from 'zod';
import { McpError, ErrorCode } from '@modelcontextprotocol/sdk/types.js';

const inputSchema = z.object({
  path: z.string().describe('File path to read'),
});

export function registerReadFileTool(server: McpServer) {
  server.tool(
    'read_file',
    'Read contents of a file',
    inputSchema.shape,
    async (args) => {
      const { path } = inputSchema.parse(args);

      try {
        // Implementation
        const content = await readFile(path, 'utf-8');
        return {
          content: [{ type: 'text', text: content }],
        };
      } catch (error) {
        throw new McpError(
          ErrorCode.InternalError,
          `Failed to read file: `
        );
      }
    }
  );
}

Resource Provider (src/resources/.ts)

import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';

export function registerFileResource(server: McpServer) {
  server.resource(
    'file:///{path}',
    'File Resource',
    'Access file contents by path',
    async (uri) => {
      const path = uri.pathname;

      const content = await readFile(path, 'utf-8');

      return {
        contents: [{
          uri: uri.href,
          mimeType: 'text/plain',
          text: content,
        }],
      };
    }
  );
}

Dependencies

{
  "dependencies": {
    "@modelcontextprotocol/sdk": "^1.0.0",
    "zod": "^3.22.0"
  },
  "devDependencies": {
    "@types/node": "^20.0.0",
    "typescript": "^5.0.0",
    "vitest": "^1.0.0"
  }
}

Transport Configurations

Stdio (Default)

import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
const transport = new StdioServerTransport();

SSE (HTTP Server-Sent Events)

import { SSEServerTransport } from '@modelcontextprotocol/sdk/server/sse.js';
import express from 'express';

const app = express();
app.get('/sse', (req, res) => {
  const transport = new SSEServerTransport('/message', res);
  server.connect(transport);
});

WebSocket

import { WebSocketServerTransport } from '@modelcontextprotocol/sdk/server/websocket.js';
import { WebSocketServer } from 'ws';

const wss = new WebSocketServer({ port: 3000 });
wss.on('connection', (ws) => {
  const transport = new WebSocketServerTransport(ws);
  server.connect(transport);
});

Workflow

1. Validate inputs - Check server name, tool/resource definitions
2. Create project structure - Set up folders and base files
3. Generate package.json - Configure dependencies
4. Generate tsconfig.json - TypeScript configuration
5. Create server entry - Main server setup
6. Generate transport layer - Selected transport implementation
7. Scaffold tools - Tool handlers with schemas
8. Scaffold resources - Resource providers
9. Create utilities - Validation, errors, logging
10. Set up tests - Test structure for tools/resources

Best Practices Applied

• Zod schema validation for all inputs
• Proper MCP error codes and messages
• Structured logging to stderr
• Clean separation of tools/resources
• TypeScript strict mode
• Comprehensive error handling
• Input sanitization
