Quiz: Your MCP Stack

1. What does 'one server per domain' mean?

Each internet domain needs its own server Don't install two different servers for the same functional area — replace rather than supplement Each server should only connect to one API You can only run one server at a time

2. When is MCP the wrong choice?

When you need to access external services When you already have a good CLI tool, when a direct API call is simpler, or when latency matters When the data source requires authentication When you need database queries

3. Why should tools do one thing?

Claude Code has a complexity limit per tool Single-purpose tools are faster Composition belongs at Claude's level — give it primitives and let it combine them Testing is easier with single-purpose tools
