I Added 5 MCP Servers to Claude Code — Here's What Actually Worked (and What Didn't)

I connected Claude Code to Godot, Chrome, and GitHub — all at once. No switching tabs. No copy-pasting between tools. Just Claude Code calling into each service directly, mid-conversation. This is a real-world review of 5 MCP servers I've set up and tested in a live AI agent system. Not a summary of the official docs — actual field notes, including the mistakes, the WSL2 timeouts, and the server that silently breaks if you forget one line. What Is MCP (And Why It's Not Just Another Plugin System) Model Context Protocol (MCP) was announced by Anthropic in November 2024. It's now part of the Linux Foundation. The short version: MCP is a standardized protocol that lets Claude Code call external tools. Your LLM can directly access file systems, GitHub, databases, game engines — anything with an MCP server. Think of it like this: Without MCP → you copy-paste between Claude and your tools With MCP → Claude calls your tools directly, mid-conversation, with full context The underlying mechanis
