MCP Builder

Overview

Build production-quality MCP (Model Context Protocol) servers that expose tools, resources, and prompts to AI clients. This skill covers the full development lifecycle: tool definition, resource management, prompt templates, transport configuration (stdio, SSE), error handling, security hardening, testing, and client integration.

Phase 1: Design

1. Identify capabilities to expose (tools, resources, prompts)
2. Define tool schemas with Zod/JSON Schema
3. Plan resource URI patterns
4. Design error handling strategy
5. Choose transport layer (stdio for CLI, SSE for web)

STOP — Present the capability inventory and transport choice to user for approval.
