The short answer
A model context protocol is a shared interface for connecting models to external tools, data, and actions with clearer discovery and contracts.
A protocol gives an ecosystem a common language. For AI applications, that language can describe what tools exist, what resources are available, and how a model can use them.
Without a shared contract, every integration invents its own discovery and invocation patterns. Protocols reduce that repeated work.
A protocol does not make a tool safe or a workflow correct. Teams still need permissions, validation, monitoring, and careful product design.
