SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Building a Model Context Protocol server from scratch requires understanding JSON-RPC transports, capability declarations, tool schemas, and Claude Desktop configuration, which is error-prone without a structured reference. ## Core Features & Use Cases - Complete Server Scaffolding: Provides TypeScript project setup, server initialization, and stdio or HTTP/SSE transport configuration using the official MCP SDK. - Tools, Resources, and Prompts: Includes patterns for defining tool schemas with Zod validation, static and dynamic resources, and reusable prompt templates. - Testing and Deployment: Covers MCP Inspector testing, unit tests with Vitest, error handling with MCP error codes, and Claude Desktop configuration. - Use Case: When you need Claude to query your internal database or call the GitHub API, use this Skill to generate a working MCP server with validated tool handlers and a ready-to-use Claude Desktop config entry. ## Quick Start Use the mcp-server-builder skill to create a TypeScript MCP server that exposes a tool for listing GitHub issues and configure it for Claude Desktop.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create an MCP server for Claude?▼

Create a TypeScript project, install @modelcontextprotocol/sdk and zod, then instantiate a Server with declared capabilities and register handlers for tools, resources, or prompts. Connect it via StdioServerTransport and add it to the Claude Desktop config file.

How to test an MCP server locally before deployment?▼

Run your server with the MCP Inspector using npx @modelcontextprotocol/inspector node dist/index.js. The inspector lets you invoke tools, read resources, and verify responses interactively before configuring Claude Desktop.

What is the difference between stdio and HTTP/SSE transport in MCP?▼

Stdio transport runs the server as a local subprocess communicating over standard input and output, suited for Claude Desktop. HTTP/SSE transport exposes the server over a network endpoint, suited for remote or multi-client deployments.

Does MCP server support input validation for tools?▼

Yes, tool inputs can be validated with Zod schemas before handler execution. Invalid parameters should throw an McpError with the InvalidParams error code so Claude receives a clear, actionable error message.

Why is my MCP server output not reaching Claude?▼

MCP communicates over stdout, so any console.log statements corrupt the protocol stream. Write logs to stderr using console.error instead, and ensure tool responses return content arrays with typed text entries.
