MCP
also Model Context Protocol
An open standard from Anthropic that defines how AI applications connect to external tools, data, and context through a consistent client-server protocol.
Analogy
Like a USB-C port for AI: one standard plug so any model can connect to any compliant tool or data source.
Why it matters
It lets Claude connect to systems like GoHighLevel or databases through a reusable interface instead of custom one-off integrations.
In practice
Connecting Claude to a GitHub MCP server so it can read issues and open pull requests.
