Building Your Own MCP Server for Claude Code

This guide will walk you through creating a custom MCP (Model Context Protocol) server that integrates with Claude Code, allowing you to extend Claude's capabilities with external tools, APIs, or even other AI models.

What is MCP?

MCP (Model Context Protocol) is a protocol that allows Claude to communicate with external servers to access tools and capabilities beyond its built-in features. Think of it as a plugin system for Claude.

Introduction

The present discussion is a contribution to the understanding of what programming is. It suggests that programming properly should be regarded as an activity by which the programmers form or achieve a certain kind of insight, a theory, of the matters at hand. This suggestion is in contrast to what appears to be a more common notion, that programming should be regarded as a production of a program and certain other texts.

	# Fact: you don't want WordPress core files, or your server-specific

	# Solution: stick this file up your repository root (which it assumes is
	# also the WordPress root directory) and add exceptions for any plugins,
	# themes, and other directories that should be under version control.
