What is Model Context Protocol (MCP)

Definition

Model Context Protocol (MCP) is an open protocol for connecting AI applications to tools, data sources and external context. In practical AI work, it helps teams connect a concept to data, model behavior, product choices and evaluation. The useful question is not only what the term means, but how it affects quality, cost, reliability and risk in a real workflow.

Example

A team uses Model Context Protocol (MCP) to choose a model, design an experiment, compare alternatives or check whether an AI tool fits the task.

Why it matters

Model Context Protocol (MCP) matters because infrastructure decisions shape speed, cost, reliability, security and what an AI product can do in production.

How it works

Teams define data flows, compute requirements, deployment targets and access patterns, then test reliability, cost and security under load. For Model Context Protocol (MCP), the key is to connect the definition with input data, assumptions, measurable outcomes and deployment limits.

Where it is used

• Used in model platforms, data systems, deployment pipelines, monitoring, libraries, hardware acceleration and production AI services.

Limitations

Infrastructure choices can hide cost, latency, security, reliability and maintenance tradeoffs, so they must be tested in realistic conditions.
