MCP lets your AI assistant use real tools — search Slack, manage GitHub repos, read files, query databases, and hundreds more. Without MCP, your AI can only talk. With MCP, it can do things.
What changes?
Without MCP
You ask Claude:
"What did my team discuss on Slack today?"
✗
Claude says: "I don't have access to your Slack. You'll need to copy-paste the messages here."
With MCP
You ask Claude:
