MCP Skills Update Summary — February 3, 2026

What Was Done

Based on learnings from building 30+ MCP servers and 11 GHL MCP Apps, I've created 3 new skills and updated 1 existing skill to capture production patterns and get it right on attempt 1 in the future.

New Skills Created

1. mcp-server-development ⭐

Location: ~/.clawdbot/skills/mcp-server-development/SKILL.md

Covers:

  • Complete TypeScript MCP server template (one-file pattern)
  • Tool naming conventions (verb_noun)
  • Input schema best practices
  • Tool metadata with labels (categorization, visibility, complexity)
  • Lazy-loaded resources (on-demand data fetching)
  • Resource templates (dynamic URIs with parameters)
  • Progress notifications (long-running operations)
  • Structured logging (debug, info, warning, error levels)
  • Prompts (predefined prompt templates)
  • Roots listing (for file system-like structures)
  • API client patterns (OAuth, API key, token management)
  • Error handling patterns
  • Pagination handling
  • Environment variable management
  • Build & deployment workflow
  • When to split into multiple files (500+ lines)

Extracted from: 30 production servers (ServiceTitan, Gusto, Mailchimp, Calendly, Toast, Zendesk, Trello, Pipedrive, etc.)

BONUS: 2026-BLUEPRINT.md — Definitive build checklist for Feb 2026-optimized MCP servers

  • 11-phase build process (planning → deployment)
  • Production checklist with all modern features
  • Anti-patterns to avoid
  • Golden rules (10 commandments for MCP servers)

Key patterns documented:

  • One-file approach for most servers
  • Switch statement tool handler
  • Consistent error wrapping
  • Page/pageSize pagination with max caps
  • ISO 8601 date handling
  • Environment validation on startup

2. mcp-apps-integration ⭐

Location: ~/.clawdbot/skills/mcp-apps-integration/SKILL.md

Covers:

  • When to use apps vs regular tools
  • MCPAppsManager class pattern
  • Server integration (resources + tools)
  • HTML UI component templates
  • Build configuration (copy UI files to dist/)
  • Common UI patterns (grids, cards, dashboards, timelines)
  • Testing apps in Claude Desktop
  • App tool naming convention (view_/show_ prefix)

Extracted from: 11 GHL MCP Apps (Contact Grid, Pipeline Board, Calendar View, Opportunity Card, Invoice Preview, Campaign Stats, Agent Stats, Contact Timeline, Workflow Status, Quick Book, Dashboard)

Key patterns documented:

  • Resource handler registration
  • structuredContent return format
  • UI file path resolution (ESM __dirname equivalent)
  • Fallback HTML generation
  • window.addEventListener('message') pattern

3. mcp-deployment ⭐

Location: ~/.clawdbot/skills/mcp-deployment/SKILL.md

Covers:

  • Local deployment (Claude Desktop config)
  • Docker containerization (multi-stage build)
  • Railway deployment (railway.json)
  • npm publishing (package.json setup, .npmignore)
  • GitHub repository structure
  • CI/CD with GitHub Actions
  • README templates
  • Version management (semantic versioning)
  • Distribution checklist

Extracted from: Deployment configs across all 30 servers + marketing repos

Key patterns documented:

  • Multi-stage Dockerfile
  • Railway.json with environment variables
  • npm publish workflow
  • GitHub Actions build + publish automation
  • .env.example templates
  • README structure with installation options

Existing Skills Updated

4. mcp-apps-official

Location: ~/.clawdbot/workspace/skills/mcp-apps-official/SKILL.md

Added section: "Real-World Examples from Production Apps"

What was added:

  • All 11 GHL app examples with tool definitions
  • Pattern breakdown (static display, client-side interactivity, drag-drop, form submission, dashboards)
  • Common patterns across apps
  • Lessons learned (send all data upfront, use updateModelContext for silent tracking, avoid premature callServerTool, etc.)
  • Reference implementations with file paths

Why: The skill was already comprehensive on SDK patterns, but lacked concrete production examples. Now it has 11 real apps as reference.

  • /Users/jakeshore/.clawdbot/workspace/skill-updates/summary.md — This file

What This Enables

Before (Pain Points)

  • Had to remember TypeScript MCP server structure every time
  • No documentation of patterns used across 30 servers
  • App integration required reading old code to remember approach
  • Deployment configs rebuilt from scratch each time
  • No concrete examples of production apps

After (Benefits)

  • MCP server template → Copy/paste and start building
  • Tool patterns documented → Naming, schemas, pagination, errors
  • App integration guide → MCPAppsManager class + UI pattern
  • Deployment templates → Dockerfile, railway.json, package.json configs
  • 11 real app examples → Reference for any UI pattern needed
  • Get it right on attempt 1 → No more "clean it up later" cycles

Next Steps (Recommendations)

  1. Test new skills — Try building a new MCP server using the templates to verify completeness
  2. Update mcporter skill — Add examples from our 30 servers (low priority)
  3. Create skill index — Searchable index of all skills with when-to-use guidance
  4. Skill versioning — Track when skills were last updated based on new learnings

Metrics

  • New skills created: 3
  • Existing skills updated: 1
  • Total MCP knowledge captured: 30 servers + 11 apps + deployment workflows
  • Lines of documentation: ~20K lines across 3 new skills
  • Production patterns documented: 50+ (tool naming, pagination, auth, UI components, deployment configs, etc.)

Summary: We've now captured ALL the MCP knowledge from building 30+ servers and 11 apps into reusable skills. Next MCP server or app should be significantly faster to build and get right the first time.
