What is Model Context Protocol?

A plain-English guide to MCP, connected AI tools, servers, clients, and external data sources.

Model Context Protocol, usually shortened to MCP, is a way for AI tools to connect with external information and services in a more structured way. Instead of every AI tool needing a custom integration for every file, database, or application, MCP gives developers a shared pattern for connecting tools and data sources.

For most beginners, the best next step is not to chase every advanced feature. It is to learn one practical workflow, understand what each step does, and repeat that process until the tool makes sense.
