Step 1 of 3 — The bridge between chat and action
What MCP Is
Right now, Claude can answer questions. With MCP (Model Context Protocol), Claude can DO things — read your calendar, update your database, post to social media, check your inventory. It's the difference between an advisor and an employee.
What happens
- MCP = standard protocol for AI-to-tool communication
- A "server" wraps your existing APIs/databases in a format Claude understands
- Tools define: name, description, inputs, outputs — Claude figures out when to use them
- Resources let Claude read data (like a database view or config file)
- Works with Claude Code, Claude Desktop, and any MCP-compatible client
- Your data stays on your machine — nothing sent to Anthropic except the tool results
Real example
QUERY
What can an MCP server do?
FINDING
Real examples running today: read/write Airtable tasks, query Shopify orders, send emails via Resend, read Google Calendar, post to Buffer, search a knowledge brain, manage DNS records, send Telegram messages
THE FIX
Each of these is a 50-100 line TypeScript function. Not complex. Just a wrapper around an API you already use.
Try it yourself
Think of one tool you use daily that you wish Claude could access. Your calendar? Your task list? Your CRM? That's your first MCP server.
