MCP Server Architecture Upgrade Summary

Date: 2025-02-14 Task: Upgrade 5 MCP servers from simple index.ts to proper main.ts + server.ts architecture with lazy loading

Servers Upgraded

1. ✅ Trello

• Location: /mcpengine-repo/servers/trello/
• Tool Files: 14 (boards, lists, cards, checklists, members, organizations, labels, actions, custom-fields, notifications, search, webhooks, power-ups, tokens)
• Changes:
  • Created src/main.ts with env validation (TRELLO_API_KEY, TRELLO_TOKEN) + graceful shutdown
  • Created src/server.ts with TrelloMCPServer class + lazy-loaded tool modules
  • Renamed src/index.ts → src/index.ts.bak
  • Updated package.json: main and bin now point to dist/main.js
• Verification: npx tsc --noEmit ✅ 0 errors

2. ✅ TouchBistro

• Location: /mcpengine-repo/servers/touchbistro/
• Tool Files: 8 (orders, menu, tables, staff, customers, reservations, inventory, payments)
• Changes:
  • Created src/main.ts with env validation (TOUCHBISTRO_API_KEY, TOUCHBISTRO_RESTAURANT_ID) + graceful shutdown
  • Created src/server.ts with TouchBistroMCPServer class + lazy-loaded tool modules
  • Renamed src/index.ts → src/index.ts.bak
  • Updated package.json: main and bin now point to dist/main.js
• Verification: npx tsc --noEmit ✅ 0 errors

3. ✅ CloseBot

• Location: /mcpengine-repo/servers/closebot/
• Tool Files: 8 (bot-management, source-management, lead-management, analytics, bot-testing, library, agency-billing, configuration)
• Changes:
  • Created src/main.ts with env validation (CLOSEBOT_API_KEY) + graceful shutdown
  • Created src/server.ts with CloseBotMCPServer class + lazy-loaded tool modules
  • Renamed src/index.ts → src/index.ts.bak
  • Updated package.json: main and bin now point to dist/main.js
• Verification: npx tsc --noEmit ✅ 0 errors

4. ✅ Close

• Location: /mcpengine-repo/servers/close/
• Tool Files: 12 (leads, contacts, opportunities, activities, tasks, smart-views, users, custom-fields, sequences, reporting, pipelines, bulk)
• Changes:
  • Created src/main.ts with env validation (CLOSE_API_KEY) + graceful shutdown
  • Created src/server.ts with CloseMCPServer class + lazy-loaded tool modules
  • Renamed src/index.ts → src/index.ts.bak
  • Updated package.json: main and bin now point to dist/main.js
• Verification: npx tsc --noEmit ✅ 0 errors

5. ✅ Google Console

• Location: /mcpengine-repo/servers/google-console/
• Tool Files: 6 (discovery, analytics, intelligence, indexing, management, sitemaps)
• Changes:
  • Created src/main.ts with auth initialization + cache/rate limiter setup + graceful shutdown
  • Kept existing src/server.ts (already had GSCServer class with lazy loading)
  • Renamed src/index.ts → src/index.ts.bak
  • Updated package.json: main and bin now point to dist/main.js
• Verification: npx tsc --noEmit ✅ 0 errors

Architecture Pattern (Gold Standard)

main.ts

• ✅ #!/usr/bin/env node shebang
• ✅ Environment variable validation with clear error messages
• ✅ Instructions for where to get API keys
• ✅ Graceful shutdown handlers (SIGINT/SIGTERM)
• ✅ Creates API client → creates server → starts transport
• ✅ Stdio transport (default)

server.ts

• ✅ SERVER CLASS pattern (e.g., TrelloMCPServer, TouchBistroMCPServer)
• ✅ toolModules: Map<string, () => Promise<ToolModule>> for lazy loading
• ✅ setupToolModules() registers each tool file via dynamic import
• ✅ setupHandlers() registers ListToolsRequestSchema + CallToolRequestSchema
• ✅ loadAllTools() resolves all lazy modules on first request
• ✅ Capabilities: { tools: {}, resources: {} } (where applicable)

Files Preserved

All original index.ts files renamed to index.ts.bak for safety. No tool files or client files were modified.

Next Steps

• Build each server: npm run build
• Test each server with MCP inspector
• Deploy to production

Notes

• All servers compile with 0 TypeScript errors
• All servers follow the exact same architectural pattern
• Environment validation provides helpful setup instructions
• Graceful shutdown ensures clean process termination
• Lazy loading improves startup performance
