MCP: wire Claude into the tools you actually use

Claude with no MCP is the smartest person you know, locked in a room, with no phone.

It can reason about your business brilliantly.
It just cannot see your database,
cannot read your repo,
cannot open a browser,
cannot check what Stripe says about last month.

So you paste. Screenshots, CSV exports, half a schema, three Slack threads. Then you do it again tomorrow.

MCP is the protocol that ends that. One standard way for Claude to reach outside itself. Open, free, and already supported by GitHub, Stripe, Notion, Sentry, Linear and a few hundred others.

Most people set it up wrong. They install eleven servers, load four hundred tools, and burn half their context window before typing a word.

I wrote the guide I wanted when I started. Real commands, a full config file you can copy, the five servers worth installing first, and an honest security section about what write access actually means.

Free. No email wall.
