Building a simple MCP server (conceptually)
Declare tools (name, schema, handler), expose over stdio.
Difficulty 2/5
Short
Plain English
Declare tools (name, schema, handler), expose over stdio. Picture it like this: Wiring a USB device's buttons to functions. In the apps you ship (Agentify, wedding portals, CRM), you will bump into this on almost every screen — name it clearly when you prompt your coding agent.

Common mistakes
- Letting the AI rename this concept three different ways in one PR.
- Building UI before you can say what is stored and who can change it.
AI-agent trap
Agents may invent jargon here. Ask them to explain the concept in plain English first, then map it to your schema and one real screen.
Summary
Declare tools (name, schema, handler), expose over stdio. Wiring a USB device's buttons to functions. Ask yourself: where does this live in the database, which function changes it, and which screen shows it?
